|
A. Distribution or Redistribution of the Subject Software must be made
|
||||||
|
under this Agreement except for additions covered under paragraph 3H.
|
||||||
|
|
||||||
|
1. Whenever a Recipient distributes or redistributes the Subject
|
||||||
|
Software, a copy of this Agreement must be included with each copy
|
||||||
|
of the Subject Software; and
|
||||||
|
2. If Recipient distributes or redistributes the Subject Software in
|
||||||
|
any form other than source code, Recipient must also make the
|
||||||
|
source code freely available, and must provide with each copy of
|
||||||
|
the Subject Software information on how to obtain the source code
|
||||||
|
in a reasonable manner on or through a medium customarily used for
|
||||||
|
software exchange.
|
||||||
|
|
||||||
|
B. Each Recipient must ensure that the following copyright notice

|
||||||
|
|
||||||
|
C. Each Contributor must characterize its alteration of the Subject
|
||||||
|
Software as a Modification and must identify itself as the originator
|
||||||
|
of its Modification in a manner that reasonably allows subsequent
|
||||||
|
Recipients to identify the originator of the Modification. In
|
||||||
|
fulfillment of these requirements, Contributor must include a file
|
||||||
|
(e.g., a change log file) that describes the alterations made and the
|
||||||
|
date of the alterations, identifies Contributor as originator of the
|
||||||
|
alterations, and consents to characterization of the alterations as a
|
||||||
|
Modification, for example, by including a statement that the
|
||||||
|
Modification is derived, directly or indirectly, from Original
|
||||||
|
Software provided by Government Agency. Once consent is granted, it
|
||||||
|
may not thereafter be revoked.
|
||||||
|
|
||||||
|
D. A Contributor may add its own copyright notice to the Subject
|
||||||
|
Software. Once a copyright notice has been added to the Subject
|
||||||
|
Software, a Recipient may not remove it without the express permission
|
||||||
|
of the Contributor who added the notice.
|
||||||
|
|
||||||
|
E. A Recipient may not make any representation in the Subject Software
|
||||||
|
or in any promotional, advertising or other material that may be
|
||||||
|
construed as an endorsement by Government Agency or by any prior
|
||||||
|
Recipient of any product or service provided by Recipient, or that may
|
||||||
|
seek to obtain commercial advantage by the fact of Government Agency's
|
||||||
|
or a prior Recipient's participation in this Agreement.
|
||||||
|
|
||||||
|

||||||
|
Subject Software, each Recipient, upon receipt of the Subject
|
||||||
|
Software, is requested to register with Government Agency by visiting
|
||||||
|
the following website: http://opensource.arc.nasa.gov. Recipient's
|
||||||
|
name and personal information shall be used for statistical purposes
|
||||||
|
only. Once a Recipient makes a Modification available, it is requested
|
||||||
|
that the Recipient inform Government Agency at the web site provided
|
||||||
|
above how to access the Modification.
|
||||||
|
|
||||||
|
G. Each Contributor represents that that its Modification is believed
|
||||||
|
to be Contributor's original creation and does not violate any
|
||||||
|
existing agreements, regulations, statutes or rules, and further that
|
||||||
|
Contributor has sufficient rights to grant the rights conveyed by this
|
||||||
|
Agreement.
|
||||||
|
|
||||||
|
H. A Recipient may choose to offer, and to charge a fee for, warranty,
|
||||||
|
support, indemnity and/or liability obligations to one or more other
|
||||||
|
Recipients of the Subject Software. A Recipient may do so, however,
|
||||||
|
only on its own behalf and not on behalf of Government Agency or any
|
||||||
|
other Recipient. Such a Recipient must make it absolutely clear that
|
||||||
|
any such warranty, support, indemnity and/or liability obligation is
|
||||||
|
offered by that Recipient alone. Further, such Recipient agrees to
|
||||||
|
indemnify Government Agency and every other Recipient for any
|
||||||
|
liability incurred by them as a result of warranty, support, indemnity
|
||||||
|
and/or liability offered by such Recipient.
|
||||||
|
|
||||||
|
I. A Recipient may create a Larger Work by combining Subject Software
|
||||||
|
with separate software not governed by the terms of this agreement and
|
||||||
|
distribute the Larger Work as a single product. In such case, the
|
||||||
|
Recipient must make sure Subject Software, or portions thereof,
|
||||||
|
included in the Larger Work is subject to this Agreement.
|
||||||
|
|
||||||
|
J. Notwithstanding any provisions contained herein, Recipient is
|
||||||
|
hereby put on notice that export of any goods or technical data from

the United States may require some form of export license from the
|
||||||
|
U.S. Government. Failure to obtain necessary export licenses may
|
||||||
|
result in criminal liability under U.S. laws. Government Agency
|
||||||
|
neither represents that a license shall not be required nor that, if
|
||||||
|
required, it shall be issued. Nothing granted herein provides any
|
||||||
|
such export license.

Shift Installation and Configuration
|
||||||
|
====================================
|
||||||
|
|
||||||
|
1. Deployments
|
||||||
|
|
||||||
|
Shift consists of three executable components:
|
||||||
|
|
||||||
|
o shiftc - the Shift client, which is invoked by users and other
|
||||||
|
client instances and must exist on hosts that initiate
|
||||||
|
transfers and hosts on which a transfer is to be
|
||||||
|
parallelized (henceforth called "client hosts")
|
||||||
|
|
||||||
|
o shift-mgr - the Shift manager, which is invoked by client instances
|
||||||
|
and must exist either on all client hosts or on a host
|
||||||
|
accessible via ssh hostbased or pubkey authentication
|
||||||
|
(henceforth called "manager hosts")
|
||||||
|
|
||||||
|
o shift-aux - the Shift auxiliary utility, which is invoked by client
|
||||||
|
instances and is optional for basic functionality, but
|
||||||
|
must be installed on any hosts accessed as the source or
|
||||||
|
destination of a transfer initiated from a different host
|
||||||
|
(henceforth called "remote hosts") for efficient remote
|
||||||
|
file initialization, higher speed transfers via the
|
||||||
|
built-in fish/fish-tcp protocols, remote acl/xattr
|
||||||
|
preservation, remote lustre striping, and remote
|
||||||
|
verification (if msum from mutil is not installed)
|
||||||
|
|
||||||
|
The main consideration for a Shift deployment is deciding which hosts will
|
||||||
|
be the manager hosts. In the simplest case, all client hosts are manager
|
||||||
|
hosts. If there is more than one client host, then the manager must be
|
||||||
|
configured to store its metadata on a shared file system that supports
|
||||||
|
locking.
|
||||||
|
|
||||||
|
In a more complex multi-user, multi-host environment without a shared file
|
||||||
|
system across all potential client hosts, one or more hosts must be
|
||||||
|
designated as manager hosts. Since the manager is not an active server
|
||||||
|
and is simply a passive executable invoked by clients, the manager can be
|
||||||
|
located on any host with ssh access. These hosts must support either
|
||||||
|
hostbased or pubkey authentication, however, since Shift is an automated
|
||||||
|
framework that performs actions without the user present. The manager has
|
||||||
|
a synchronization mechanism allowing multiple hosts without a shared file
|
||||||
|
system to be used for redundancy.
|
||||||
|
|
||||||
|
|
||||||
|

|
|
||||||
|
3. Installation
|
||||||
|
|
||||||
|
Note that the following shows the exact files needed on each type of host.
|
||||||
|
Since the number of files is small, however, there is minimal penalty to
|
||||||
|
simply installing them all on every host.
|
||||||
|
|
||||||
|
3.1. Single-user installation
|
||||||
|
|
||||||
|
Note that the user's home directory is used as the default install
|
||||||
|
prefix in all examples, but can be changed to any other desired location
|
||||||
|
as long as the corresponding bin directory is in the user's path.
|
||||||
|
|
||||||
|
3.1.1. Client hosts
|
||||||
|
|
||||||
|
install -m 700 perl/shiftc ~/bin/shiftc
|
||||||
|
install -m 600 doc/shiftc.1 ~/man/man1/shiftc.1
|
||||||
|
|
||||||
|
3.1.2. Manager hosts
|
||||||
|
|
||||||
|
install -m 700 perl/shift-mgr ~/bin/shift-mgr
|
||||||
|
install -m 600 etc/shiftrc ~/.shiftrc
|
||||||
|
|
||||||
|
3.1.3. Remote hosts (optional but recommended when possible)
|
||||||
|
|
||||||
|
install -m 700 perl/shift-aux ~/bin/shift-aux
|
||||||
|
|
||||||
|
3.2. Multi-user installation
|
||||||
|
|
||||||
|
Note that /usr/local is used as the default install prefix in all
|
||||||
|
examples, but can be changed to any other desired location as long
|
||||||
|
as the corresponding bin directory is in the default system path.
|
||||||
|
|
||||||
|
3.2.1. Client hosts
|
||||||
|
|
||||||
|
install -m 755 perl/shiftc /usr/local/bin/shiftc
|
||||||
|
install -m 644 doc/shiftc.1 /usr/local/man/man1/shiftc.1
|
||||||
|
|
||||||
|
3.2.2. Manager hosts
|
||||||
|
|
||||||
|
install -m 755 perl/shift-mgr /usr/local/bin/shift-mgr
|
||||||
|
install -m 644 etc/shiftrc /etc/shiftrc
|
||||||
|
|
||||||
|
3.2.3. Remote hosts (optional but recommended when possible)
|
||||||
|
|
||||||
|
install -m 755 perl/shift-aux /usr/local/bin/shift-aux
|
||||||
|
|
||||||
|
|
||||||
|
4. Configuration
|
||||||
|
|
||||||
|
4.1. Client hosts
|
||||||
|
|
||||||
|
4.1.1. ~/.ssh/id_rsa (or similar)
|
||||||
|
|
||||||
|
If hostbased authentication is not supported by client hosts,
|
||||||
|
manager hosts, and/or remote hosts, pubkey authentication must be
|
||||||
|
used. Clients must have access to private keys to access these
|
||||||
|
systems, which may either be referenced explicitly via the
|
||||||
|
--mgr-identity and --identity options for manager and remote
|
||||||
|
hosts, respectively, or be added to an ssh agent on the client(s).
|
||||||
|
Note that the private keys used for these options must not be
|
||||||
|
protected by a passphrase. The use of an ssh agent to access
|
||||||
|
manager or remote hosts may be preferable from a security standpoint
|
||||||
|
but comes with a drop in reliability as any failure of the agent or
|
||||||
|
agent host leaves any associated transfers with no way to recover.
|
||||||
|
|
||||||
|
4.1.2. ~/.ssh/authorized_keys
|
||||||
|
|
||||||
|
If hostbased authentication is not supported to other client hosts
|
||||||
|
for parallelization, pubkey authentication must be used. In this
|
||||||
|
case, the public key(s) corresponding to the private key(s) used by
|
||||||
|
clients (those named ~/.ssh/id* loaded into an ssh agent) must be
|
||||||
|
added to the invoking user's authorized_keys file on other client
|
||||||
|
hosts.
|
||||||
|
|
||||||
|
4.1.3. ~/bin/shiftc (single-user) or /usr/local/bin/shiftc (multi-user)
|
||||||
|
|
||||||
|
If the manager hosts differ from the client hosts, the manager
|
||||||
|
host(s) can be hardcoded within the shiftc program in the
|
||||||
|
"site-specific options" section. This allows the client to be used
|
||||||
|
without specifying the --mgr option every time. For example, the
|
||||||
|
line:
|
||||||
|
|
||||||
|
$opts{"mgr"} = "mgr.example.com";
|
||||||
|
|
||||||
|
would be equivalent to specifying the option "--mgr=mgr.example.com".
|
||||||
|
In general, any shiftc command-line option --X can be hardcoded using:
|
||||||
|
|
||||||
|
$opts{"X"} = "hardcoded_value";
|
||||||
|
|
||||||
|
Those familiar with perl can add more complex logic (e.g. choosing
|
||||||
|
which manager host out of a set of hosts will be used for each
|
||||||
|
invocation).
|
||||||
|
|
||||||
|
4.2. Manager hosts
|
||||||
|
|
||||||
|
4.2.1. ~/.shiftrc (single-user) or /etc/shiftrc (multi-user)
|
||||||
|
|
||||||
|
All items in the default config file should be reviewed.
|
||||||
|
The only required setting is:
|
||||||
|
|
||||||
|
user_dir
|
||||||
|
|
||||||
|
If there are multiple manager hosts, the configured directory must
|
||||||
|
either be a file system shared across all manager hosts that
|
||||||
|
supports file locking or the setting:
|
||||||
|
|
||||||
|
sync_host
|
||||||
|
|
||||||
|
must be configured to sync the transfer metadata across two
|
||||||
|
manager hosts. Note that the existing synchronization
|
||||||
|
mechanism has been found to be a bottleneck when there are
|
||||||
|
many clients in a single transfer or many simultaneous
|
||||||
|
transfers by a single user. This will be fixed in a future
|
||||||
|
version.
|
||||||
|
|
||||||
|
The transport options should definitely be reviewed to
|
||||||
|
enable any higher performance transports that may be
|
||||||
|
available. Higher performance remote transports based on
|
||||||
|
TCP connections (fish-tcp) and SSH connections (fish) are
|
||||||
|
built-in, but require that the shift-aux executable exist
|
||||||
|
on remote hosts. Note that transports can be enabled on a
|
||||||
|
case-by-case basic using the client --local and --remote
|
||||||
|
options.
|
||||||
|
|
||||||
|
To allow Shift to make parallelization decisions and enable
|
||||||
|
functionality specific to certain remote file systems (e.g. Lustre
|
||||||
|
striping), it is desirable to configure:
|
||||||
|
|
||||||
|
db_file
|
||||||
|
|
||||||
|
with a database of host and file system information from within
|
||||||
|
the local environment. A template for producing this database is
|
||||||
|
provided in the file "etc/shift-mounts.pl". After the items
|
||||||
|
indicated in the script are configured, it can be run
|
||||||
|
once/periodically to initialize/update the file system database.
|
||||||
|
|
||||||
|
To optimize access to remote hosts on the LAN, the setting:
|
||||||
|
|
||||||
|
select_hook
|
||||||
|
|
||||||
|
may be configured to specify how remote hosts should be selected
|
||||||
|
when more than one is available. This may include deciding which
|
||||||
|
hosts are up, which are least loaded, which have the best
|
||||||
|
connectivity to the given client host, etc. A skeleton for a
|
||||||
|
suitable selection hook is provided in the file
|
||||||
|
"etc/shift-select.hook", but must be fleshed out based on
|
||||||
|
site-specific knowledge and/or calls to the local load balancing
|
||||||
|
infrastructure. If not configured, hosts will be chosen randomly
|
||||||
|
after a successful sshd ping test.
|
||||||
|
|
||||||
|
4.2.2. ~/.ssh/authorized_keys
|
||||||
|
|
||||||
|
If hostbased authentication is not supported to manager hosts,
|
||||||
|
pubkey authentication must be used. In this case, the public key(s)
|
||||||
|
corresponding to the private key(s) used by clients (either loaded
|
||||||
|
into an ssh agent or specified via --mgr-identity) must be added to
|
||||||
|
the appropriate user's authorized_keys file on manager hosts.
|
||||||
|
This user will either be the invoking user or the one specified by
|
||||||
|
--mgr-user.
|
||||||
|
|
||||||
|
|
||||||
|
4.3. Remote hosts
|
||||||
|
|
||||||
|
4.3.1. ~/.ssh/authorized_keys
|
||||||
|
|
||||||
|
If hostbased authentication is not supported to remote hosts, pubkey
|
||||||
|
authentication must be used. In this case, the public key(s)
|
||||||
|
corresponding to the private key(s) used by clients (either loaded
|
||||||
|
into an ssh agent or specified via --identity) must be added to the
|
||||||
|
appropriate user's authorized_keys file on remote hosts. This user
|
||||||
|
will either be the invoking user or the one specified by --user.
|
||||||
|
|
||||||
|
|
||||||
|
5. Usage
|
||||||
|
|
||||||
|
5.1. shiftc
|
||||||
|
|
||||||
|
Client usage is detailed in the man page "doc/shiftc.1", which can be
|
||||||
|
viewed with:
|
||||||
|
|
||||||
|
nroff -man doc/shiftc.1 |less -r
|
||||||
|
|
||||||
|
if not already in a manpath directory. Basic usage is drop-in
|
||||||
|
compatible with cp/scp with special consideration for the authentication
|
||||||
|
options --mgr, --mgr-identity, --mgr-user, --identity, and --user.
|
||||||
|
Note that the scp "user@host" syntax is not currently supported (the
|
||||||
|
"user@" portion will be dropped) so --user must be specified instead
|
||||||
|
when the remote user differs from the local user.
|
||||||
|
|
||||||
|
5.2. shift-mgr
|
||||||
|
|
||||||
|
Normal users need not invoke shift-mgr directly as all relevant manager
|
||||||
|
functionality is accessed indirectly through the client. Additional
|
||||||
|
capabilities are available for administrators, however, to aid in
|
||||||
|
collecting usage stats and debugging information. Below is a sampling
|
||||||
|
of some of the most useful administrative shift-mgr commands.
|
||||||
|
|
||||||
|
To see the status of a particular user X's transfers, run:
|
||||||
|
|
||||||
|
shift-mgr --user=X --status
|
||||||
|
|
||||||
|
To see the history of a particular user X's transfers, run:
|
||||||
|
|
||||||
|
shift-mgr --user=X --history
|
||||||
|
|
||||||
|
To see the status of running transfers across all users, run:
|
||||||
|
|
||||||
|
shift-mgr --status --state=run
|
||||||
|
|
||||||
|
To see detailed stats across the transfers of all users including a
|
||||||
|
sampling of error messages, run:
|
||||||
|
|
||||||
|
shift-mgr --stats
|
||||||
|
|
||||||
|
This can be added to a cron job (normally at the interval of the
|
||||||
|
"data_expire" setting in shiftrc) with a redirection to a file to
|
||||||
|
periodically save usage stats.
|
||||||
|
|
||||||
|
To see the metadata associated with a given user X's transfer T, run:
|
||||||
|
|
||||||
|
shift-mgr --user=X --id=T --meta
|
||||||
|
|
||||||
|
The metadata is log structured, so it is also possible to view the
|
||||||
|
metadata at any number of steps S back in time using:
|
||||||
|
|
||||||
|
shift-mgr --user=X --id=T --meta=S

Self-Healing Independent File Transfer (Shift)
|
||||||
|
==============================================
|
||||||
|
|
||||||
|
In high-end computing environments, remote file transfers of very large data
|
||||||
|
sets to and from computational resources are commonplace as users are typically
|
||||||
|
widely distributed across different organizations and must transfer in data to
|
||||||
|
be processed and transfer out results for further analysis. Local transfers
|
||||||
|
of this same data across file systems are also frequently performed by
|
||||||
|
administrators to optimize resource utilization when new file systems come
|
||||||
|
on-line or storage becomes imbalanced between existing file systems. In both
|
||||||
|
cases, files must traverse many components on their journey from source to
|
||||||
|
destination where there are numerous opportunities for performance optimization
|
||||||
|
as well as failure. A number of tools exist for providing reliable and/or high
|
||||||
|
performance file transfer capabilities, but most either do not support local
|
||||||
|
transfers, require specific security models and/or transport applications, are
|
||||||
|
difficult for individual users to deploy, and/or are not fully optimized for
|
||||||
|
highest performance.
|
||||||
|
|
||||||
|
Shift is a framework for Self-Healing Independent File Transfer that provides
|
||||||
|
high performance and resilience for local and remote transfers through a variety
|
||||||
|
of techniques. These include end-to-end integrity via cryptographic hashes,
|
||||||
|
throttling of transfers to prevent resource exhaustion, balancing transfers
|
||||||
|
across resources based on load and availability, and parallelization of
|
||||||
|
transfers across multiple source and destination hosts for increased redundancy
|
||||||
|
and performance. In addition, Shift was specifically designed to accommodate
|
||||||
|
the diverse heterogeneous environments of a widespread user base with minimal
|
||||||
|
assumptions about operating environments. In particular, Shift is unique in its
|
||||||
|
ability to provide advanced reliability and automatic single and multi-file
|
||||||
|
parallelization to any stock command-line transfer application while being
|
||||||
|
easily deployed by both individual users as well as entire organizations.
|
||||||

.SH "TRANSFER INITIALIZATION"
|
||||||
|
./"################################################################
|
||||||
|
Transfers are initialized using syntax identical to cp/scp for
|
||||||
|
local/remote transfers, respectively. The most commonly used options
|
||||||
|
during initialization are listed below.
|
||||||
|
.IP "\fB\-\-clients=NUM\fP"
|
||||||
|
Parallelize the transfer by using additional clients on each host. If
|
||||||
|
the number given is one, no additional clients will be used. A number
|
||||||
|
greater than one will fork additional processes on each host to more
|
||||||
|
fully utilize system resources and increase transfer performance.
|
||||||
|
.IP "\fB\-\-create\-tar\fP"
|
||||||
|
Create a tar file of all sources at the destination, which must be a
|
||||||
|
non-existing file name. This option implies \fB\-\-recursive\fP and
|
||||||
|
\fB\-\-no\-offline\fP. By default, multiple tar files are created at
|
||||||
|
500 GB boundaries. The split size may be changed or splitting disabled
|
||||||
|
using the \fB\-\-split\-tar\fP option. The \fB\-\-index\-tar\fP option
|
||||||
|
may be used to produce a table of contents file for each tar file
|
||||||
|
created. Note that this option cannot be used with \fB\-\-sync\fP.
|
||||||
|
.IP "\fB\-L, \-\-dereference\fP"
|
||||||
|
Always follow symbolic links to both files and directories. Note that
|
||||||
|
this can result in file and directory duplication at the destination as
|
||||||
|
all symbolic links will become real files and directories.
|
||||||
|
.IP "\fB\-d, \-\-directory\fP"
|
||||||
|
Create any missing parent directories. This option allows files to be
|
||||||
|
transferred to a directory hierarchy that may not already exist, similar
|
||||||
|
to the \fB\-d\fP option of the "install" command.
|
||||||
|
.IP "\fB\-\-exclude=REGEX\fP"
|
||||||
|
Do not transfer source files matching the given regular expression.
|
||||||
|
Note that regular expressions must be given in Perl syntax (see
|
||||||
|
perlre(1) for details) and should be quoted on the command line when
|
||||||
|
including characters normally expanded by the shell (e.g. "*"). Shell
|
||||||
|
wildcard behavior can be approximated by using ".*" in place of "*".
|
||||||
|
.IP "\fB\-\-extract\-tar\fP"
|
||||||
|
Extract all source tar files to the destination, which must be an
|
||||||
|
existing directory or non-existing directory name. This option implies
|
||||||
|
\fB\-\-no\-offline\fP. Note that only tar archives in the POSIX ustar
|
||||||
|
format are supported, but GNU extensions for large uids, gids, file
|
||||||
|
sizes, and file names are handled appropriately. Also note that this
|
||||||
|
option cannot be used with \fB\-\-sync\fP.
|
||||||
|
.IP "\fB\-\-host\-file=FILE\fP"
|
||||||
|
Parallelize the transfer by using additional clients on the hosts
|
||||||
|
specified in the given file (one host name per line). This option
|
||||||
|
implies a \fB\-\-hosts\fP value equal to the number of hosts in the file
|
||||||
|
plus any additional hosts from the \fB\-\-host\-list\fP option. Less
|
||||||
|
hosts may be used by explicitly specifying a \fB\-\-hosts\fP value.
|
||||||
|
Note that the actual number of client hosts used will depend upon number
|
||||||
|
of hosts that have equivalent access to the source and/or destination
|
||||||
|
file systems. Within PBS job scripts, this option can be set to the
|
||||||
|
$PBS_NODEFILE variable to use all nodes of the job.
|
||||||
|
.IP "\fB\-\-host\-list=LIST\fP"
|
||||||
|
Parallelize the transfer by using additional clients on the hosts
|
||||||
|
specified in the given comma-separated list. This option implies a
|
||||||
|
\fB\-\-hosts\fP value equal to the number of hosts on the list plus any
|
||||||
|
additional hosts from the \fB\-\-host\-file\fP option. Less hosts may
|
||||||
|
be used by explicitly specifying a \fB\-\-hosts\fP value. Note that the
|
||||||
|
actual number of client hosts used will depend upon number of hosts that
|
||||||
|
have equivalent access to the source and/or destination file systems.
|
||||||
|
.IP "\fB\-\-hosts=NUM\fP"
|
||||||
|
Parallelize the transfer by using additional clients on at most the
|
||||||
|
given number of hosts. If the number given is one, no additional
|
||||||
|
client hosts will be used. A number greater than one enables automatic
|
||||||
|
transfer parallelization where additional clients may be invoked on
|
||||||
|
additional hosts to increase transfer performance. Note that the actual
|
||||||
|
number of client hosts used will depend upon the number of hosts for
|
||||||
|
which Shift has file system information and the number of hosts that
|
||||||
|
have equivalent access to the source and/or destination file systems.
|
||||||
|
Client hosts will be accessed as the current user with hostbased
|
||||||
|
authentication or an existing ssh agent that contains an ssh identity
|
||||||
|
from a file matching ~/.ssh/id*.
|
||||||
|
.IP "\fB\-\-identity=FILE\fP"
|
||||||
|
Authenticate to remote systems using the given ssh identity file.
|
||||||
|
The corresponding public key must reside in the appropriate user's
|
||||||
|
~/.ssh/authorized_keys file on the remote host. Note that only
|
||||||
|
identity files without passphrases are supported. If a passphrase is
|
||||||
|
required, an ssh agent may be used instead, but with a loss of
|
||||||
|
reliability. This option is not needed if the remote host accepts
|
||||||
|
hostbased authentication from client hosts.
|
||||||
|
.IP "\fB\-I, \-\-ignore\-times\fP"
|
||||||
|
By default, the \fB\-\-sync\fP option skips the processing of files
|
||||||
|
that have the same size and modification time at the source and
|
||||||
|
destination. This option specifies that files should always be
|
||||||
|
processed by checksum regardless of size and modification time.
|
||||||
|
.IP "\fB\-\-include=REGEX\fP"
|
||||||
|
Only transfer source files matching the given regular expression.
|
||||||
|
Note that regular expressions must be given in Perl syntax (see
|
||||||
|
perlre(1) for details) and should be quoted on the command line when
|
||||||
|
including characters normally expanded by the shell (e.g. "*"). Shell
|
||||||
|
wildcard behavior can be approximated by using ".*" in place of "*".
|
||||||
|
.IP "\fB\-\-index\-tar\fP"
|
||||||
|
Create a table of contents file for each tar file created with
|
||||||
|
\fB\-\-create\-tar\fP. The table of contents will show each file in the
|
||||||
|
tar file along with permissions, user/group ownership, and size. For a
|
||||||
|
tar file "file.tar", the table of contents will be named "file.tar.toc".
|
||||||
|
Unless the \fB\-\-no\-verify\fP option is used, a checksum file will
|
||||||
|
also be created named "file.tar.sum", which is suitable as input for
|
||||||
|
"msum --check-tree -c". Note that when \fB\-\-split\-tar\fP is used,
|
||||||
|
multiple table of contents and checksum files may be created. For each
|
||||||
|
split tar file "file.tar-i.tar", the table of contents will be named
|
||||||
|
"file.tar-i.tar.toc" and the checksum file will be named
|
||||||
|
"file.tar-i.tar.sum".
|
||||||
|
.IP "\fB\-\-newer=DATE\fP"
|
||||||
|
Only transfer source files whose modification time is newer (inclusive)
|
||||||
|
than the given date. Any date string supported by the Perl
|
||||||
|
Date::Parse module can be specified. Note that this option can be
|
||||||
|
combined with \fB\-\-older\fP to specify exact date ranges.
|
||||||
|
.IP "\fB\-P, \-\-no\-dereference\fP"
|
||||||
|
Never follow symbolic links to file or directories. Note that this
|
||||||
|
can result in broken links at the destination as files and directories
|
||||||
|
referenced by symbolic links that were not explicitly transferred or
|
||||||
|
implicitly transferred using \fB\-\-recursive\fP may not exist on the
|
||||||
|
target.
|
||||||
|
.IP "\fB\-T, \-\-no\-target\-directory\fP"
|
||||||
|
Do not treat the destination specially when it is a directory or a
|
||||||
|
symbolic link to a directory. This option can be used with recursive
|
||||||
|
transfers to copy a directory's contents into an existing directory
|
||||||
|
instead of into a new subdirectory beneath it as is done by default.
|
||||||
|
.IP "\fB\-\-older=DATE\fP"
|
||||||
|
Only transfer source files whose modification time is older than the
|
||||||
|
given date. Any date string supported by the Perl Date::Parse module
|
||||||
|
can be specified. Note that this option can be combined with
|
||||||
|
\fB\-\-newer\fP to specify exact date ranges.
|
||||||
|
.IP "\fB\-\-ports=NUM1:NUM2\fP"
|
||||||
|
Use ports from the range NUM1-NUM2 for the data streams of TCP-based
|
||||||
|
transports (currently, bbcp, bbftp, fish-tcp, and gridftp). All
|
||||||
|
connections originate from the client host so the given port range must
|
||||||
|
be allowed on the network path to the remote host and by the remote host
|
||||||
|
itself.
|
||||||
|
.IP "\fB\-R, \-r, \-\-recursive\fP"
|
||||||
|
Transfer directories recursively. This option implies
|
||||||
|
\fB\-\-no\-dereference\fP.Note that any symbolic links pointing
|
||||||
|
to directories given on the command line will be followed during
|
||||||
|
recursive transfers (identical to the default behavior of cp).
|
||||||
|
.IP "\fB\-\-secure\fP"
|
||||||
|
Encrypt data during remote transfers and use secure ciphers and MACs
|
||||||
|
with SSH-based tranports. Note that this option will, in most cases,
|
||||||
|
decrease performance as it eliminates some higher performance transports
|
||||||
|
and increases CPU utilization during SSH connections.
|
||||||
|
.IP "\fB\-\-sync\fP"
|
||||||
|
Synchronize files between the source and destination, similar to the
|
||||||
|
rsync command. By default, files that have the same size and
|
||||||
|
modification time at the source and destination will not be transferred.
|
||||||
|
If the size or modification time of a file differs between the two, the
|
||||||
|
contents of the file will be compared via checksum and any portions that
|
||||||
|
differ will be transferred to the destination. To skip the size and
|
||||||
|
modification time checks and always begin with the checksum stage, use
|
||||||
|
\fB\-I\fP or \fB\-\-ignore\-times\fP. If \fB\-\-no\-verify\fP is
|
||||||
|
specified, integrity verification is not performed, which will increase
|
||||||
|
performance when there are many files at the source that are not at
|
||||||
|
the destination but will decrease performance when there are large files
|
||||||
|
that have only small changes between the source and destination.
|
||||||
|
Setting \fB\-\-retry\fP to zero with this option can be used to show
|
||||||
|
which files differ without making any changes. Note that when syncing
|
||||||
|
directories, the destination should be specified as the parent of the
|
||||||
|
location where the source directory should be transferred to. Also note
|
||||||
|
that this option cannot be used with \fB\-\-create\-tar\fP or
|
||||||
|
\fB\-\-extract\-tar\fB.
|
||||||
|
.IP "\fB\-\-user=USER\fP"
|
||||||
|
Set the user that will be used to access remote systems.
|
||||||
|
.IP "\fB\-\-wait\fP"
|
||||||
|
Block until the transfer completes and print a summary of the transfer.
|
||||||
|
This option implies \fB\-\-no\-mail\fP. An exit value of 0 indicates
|

This option was included for benchmarking and completeness purposes
|

|
and is not recommended for general use.
|

|
.IP "\fB\-\-no\-cron\fP"
|

|
Do not attempt to recover from host/process failures via cron. Note

|
"run" state until stopped.

.IP "\fB\-\-no\-offline\fP"
|

|
By default, files transferred to/from DMF-managed file systems will be
|

|
migrated to offline media as soon as the transfer completes. This
|
||||||
|
option specifies that files should not be migrated. Note that DMF may

.IP "\fB\-\-no\-preserve\fP"
|

|
By default, times, permissions, ownership, ACLs, and extended attributes
|
||||||
|
of transferred files and directories are preserved when possible.
|
||||||
|
This option specifies that these items should not be preserved. Note
|
||||||
|
that permissions may be left in various states depending on the invoking
|

|
user's umask and the transport utilized. In particular, read access at
|

|
the destination may be more permissive than read access at the source.
|

|
.IP "\fB\-\-no\-verify\fP"
|

|
By default, files are checksummed at the source and destination to
|

|
verify that they have not been corrupted and if corruption is detected,
|
||||||
|
the corrupted portion of the destination file is automatically corrected
|
||||||
|
using a partial transfer from the original source. This functionality
|

|
decreases the performance of transfers in proportion to the file size.

Choose the TCP window size and number of TCP streams of TCP-based
|
||||||
|
transports (currently, bbcp, bbftp, fish-tcp, and gridftp) based on
|
||||||
|
the given bits per second. The suffixes k, m, g, and t may be used for

|
Kb, Mb, Gb, and Tb, respectively. The default bandwidth is estimated to
|
||||||
|
be 10 Gb/s if a 10 GE adapter is found on the client host, 1 Gb/s if the
|
||||||
|
client host can be resolved to an organization domain (by default, one
|
||||||
|
of the six original generic top-level domains), and 100 Mb/s otherwise.
|
||||||
|
.IP "\fB\-\-buffer=SIZE\fP"
|
||||||
|
Use memory buffer(s) of the given size when configurable in the
|
||||||
|
underlying tranport being utilized (currently, all but rsync). The
|
||||||
|
suffixes k, m, g, and t may be used for KiB, MiB, GiB, and TiB,
|
||||||
|
respectively. The default buffer size is 4 MiB. Increasing the
|
||||||
|
buffer size trades higher memory utilization for more efficient I/O.
|
||||||
|
.IP "\fB\-\-files=COUNT\fP"
|
||||||
|
Process transfers in batches of the given number of files. The
|
||||||
|
suffixes k, m, b or g, and t may be used for 1E3, 1E6, 1E9, and 1E12,
|
||||||
|
respectively. The default batch count is 1000 files. Lowering the
|
||||||
|
batch count will increase the number of checkpoints and the overhead of
|
||||||
|
transfer management. Raising the batch count will have the opposite
|
||||||
|
effect. A batch will be sent for processing when the number of files in
|
||||||
|
the batch reaches the given value. Note that batches of less than the
|
||||||
|
given count can occur if the batch size specified by \fB\-\-size\fP is
|
||||||
|
reached first.
|
||||||
|
.IP "\fB\-\-local=LIST\fP"
|
||||||
|
Specify one or more local transports to be used for the transfer in

||||||
|
order of preference, separated by commas. Valid transports for this
|
||||||
|
option currently include bbcp, bbftp, cp, fish, fish-tcp, gridftp,
|
||||||
|
mcp, and rsync. Note that the given transport(s) will be given
|
||||||
|
priority, but may not be used in some cases (e.g. rsync is not capable
|
||||||
|
of transferring a specific portion of a file as needed by verification
|
||||||
|
mode). In such cases, the default transport based on File::Copy will be

\fB\-\-status\fP with \fB\-\-id\fP set to the given transfer identifier.
|

|
.IP "\fB\-\-preallocate=NUM\fP"
|

|
Preallocate files when their sparsity is under the given percent, where
|
||||||
|
sparsity is defined as the number of bytes a file takes up on disk
|
||||||
|
divided by its size. Note that this option will only have an effect
|
||||||
|
when the fallocate command is available, the destination file does not
|
||||||
|
already exist, and the target file system properly supports fallocate's
|
||||||
|
-n option. Also note that this option will not function properly when
|
||||||
|
either bbftp or rsync (to a DMF file system) is utilized as the
|
||||||
|
transport due to their use of temporary files.
|
||||||
|
.IP "\fB\-\-remote=LIST\fP"
|
||||||
|
Specify one or more remote transports to be used for the transfer in

|
order of preference, separated by commas. Valid transports for this
|
||||||
|
option currently include bbcp, bbftp, fish, fish-tcp, gridftp, rsync,
|
||||||
|
and sftp. Note that the given transport(s) will be given priority, but
|
||||||
|
may not be used in some cases (e.g. bbftp is not capable of transferring
|
||||||
|
files with spaces in their names and is also incompatible with
|
||||||
|
\fB\-\-secure\fP). In such cases, the default transport based on sftp
|

|
.IP "\fB\-\-retry=NUM\fP"
|
||||||
|
Retry operations deemed recoverable up to the given number of attempts
|
||||||
|
per file. The default number of retries is 2. A value of zero disables
|
||||||
|
retries. Note that disabling retries also disables the ability of
|
||||||
|
\fB\-\-sync\fP to change file contents. Also note that the given
|
||||||
|
value is cumulative across all stages of a file's processing so
|
||||||
|
different stages may not be retried the same number of times.
|
||||||
|
.IP "\fB\-\-size=SIZE\fP"
|
||||||
|
Process transfers in batches of approximately the given total file size.
|
||||||
|
The suffixes k, m, g, and t may be used for KB, MB, GB, and TB,
|
||||||
|
respectively. The default batch size is 4 GB. Lowering the batch size
|
||||||
|
will increase the number of checkpoints and the overhead of transfer
|
||||||
|
management. Raising the batch size will have the opposite effect. A
|
||||||
|
batch will be sent for processing when the total size of all files in
|
||||||
|
the batch reaches the given value. Note that batches of less than the
|
||||||
|
given size can occur if the batch count specified by \fB\-\-files\fP
|
||||||
|
is reached first.
|
||||||
|
.IP "\fB\-\-split=SIZE\fP"
|
||||||
|
Parallelize the processing of single files using chunks of the given
|
||||||
|
size. The suffixes k, m, g, and t may be used for KB, MB, GB, and TB,
|
||||||
|
respectively. The default split size is zero, which disables single
|
||||||
|
file parallelization. A split size of less than 1 GB is not
|
||||||
|
recommended. Lowering the split size will increase parallelism but
|
||||||
|
decrease the performance of each file chunk and increase the overhead of
|
||||||
|
transfer management. Raising the split size will have the opposite
|
||||||
|
effect. The ideal split size for a given file is the size of the file
|
||||||
|
divided by the number of concurrent clients available. Note that this
|
||||||
|
option does not have an effect unless \fB\-\-hosts\fP is greater than
|
||||||
|
one. Also note that this option can, in some cases, decrease remote
|
||||||
|
transfer performance as it eliminates some higher performance
|
||||||
|
transports.
|
||||||
|
.IP "\fB\-\-split\-tar=SIZE\fP"
|
||||||
|
Create tar files of around the given size when used with
|
||||||
|
\fB\-\-create\-tar\fP. When multiple tar files are created for a
|
||||||
|
destination tar file "file.tar", the resulting split tar files will be
|
||||||
|
named "file.tar-i.tar" starting from "file.tar-1.tar". The suffixes k,
|
||||||
|
m, g, and t may be used for KB, MB, GB, and TB, respectively. The
|
||||||
|
default split tar size is 500 GB. A value of zero disables splitting.
|
||||||
|
A split tar size of greater than 2 TB is not recommended. Note that
|
||||||
|
resulting tar files may still be larger than specified when source files
|
||||||
|
exist that are larger than the given size.
|
||||||
|
.IP "\fB\-\-streams=NUM\fP"
|
||||||
|
Use the given number of TCP streams in TCP-based transports (currently,
|
||||||
|
bbcp, bbftp, fish-tcp, and gridftp). The default is the number of
|
||||||
|
streams necessary to fully utilize the specified/estimated bandwidth
|
||||||
|
using the maximum TCP window size. Note that it is usually preferable
|
||||||
|
to specify \fB\-\-bandwidth\fP, which allows an appropriate number of
|
||||||
|
streams to be set automatically. Increasing the number of streams can
|
||||||
|
increase performance when the maximum window size is set too low or
|
||||||
|
there is cross-traffic on the network, but too high a value can decrease
|
||||||
|
performance due to increased congestion and packet loss.
|
||||||
|
.IP "\fB\-\-stripe=SIZE|NUM\fP"
|
||||||
|
By default, a file transferred to a Lustre file system will be striped
|
||||||
|
according to size (one stripe per GB) unless the source resides on
|
||||||
|
Lustre and has non-default striping, in which case striping will be
|
||||||
|
preserved. Directory striping is preserved when applicable. If a
|
||||||
|
positive number is specified, the stripe count of all destination files
|
||||||
|
and directories will be set to the given value. If the given value is a
|
||||||
|
size (specified with the suffixes k, m, g, and t for KB, MB, GB, and TB,
|
||||||
|
respectively), files will be allocated one stripe per given size while
|
||||||
|
directories will be striped according to the default policy. A value of
|
||||||
|
zero disables automatic striping and uses the default policy for all
|
||||||
|
files and directories.
|
||||||
|
.IP "\fB\-\-threads=NUM\fP"
|
||||||
|
Use the given number of threads in multi-threaded transports and
|
||||||
|
checksum utilities (currently, mcp and msum). The default number of
|
||||||
|
threads is 4. Increasing the number of threads can increase
|
||||||
|
transfer/checksum performance when a host has excess resource capacity,
|
||||||
|
but can reduce performance when any associated resource has reached
|
||||||
|
its maximum.
|
||||||
|
.IP "\fB\-\-verify\-fast\fP"
|
||||||
|
Checksum files at the source and destination to verify that they have
|
||||||
|
not been corrupted. If corruption is detected in a file, the corrupted
|
||||||
|
portion will be automatically corrected using a partial transfer. This
|
||||||
|
option differs from the default verification in that the source buffer
|
||||||
|
will be reused when possible for the source checksum calculations. This
|
||||||
|
potentially increases performance up to 33%, but is more subject to
|
||||||
|
corruption as the source is only read once.
|
||||||
|
.IP "\fB\-\-window=SIZE\fP"
|
||||||
|
Use a TCP send/receive window of the given size in TCP-based transports
|
||||||
|
(currently, bbcp, bbftp, fish-tcp, and gridftp). The suffixes k, m,
|
||||||
|
g, and t may be used for KB, MB, GB, and TB, respectively. The default
|
||||||
|
is the product of the specified/estimated bandwidth and the round-trip
|
||||||
|
time between source and destination. Note that it is usually preferable
|
||||||
|
to specify \fB\-\-bandwidth\fP, which allows an appropriate window size
|
||||||
|
to be set automatically. Increasing the window size allows TCP to
|
||||||
|
operate more efficiently over high bandwidth and/or high latency
|
||||||
|
networks, but too high a value can overrun the receiver and cause packet
|
||||||
|
loss.
