NAME

chirp_distribute - copy a directory from one Chirp server to one or more Chirp server(s).

SYNOPSIS

chirp_distribute [options] <sourcehost> <sourcepath> <host1> <host2> <host3> ...

DESCRIPTION

chirp_distribute is a tool for coping commonly used data across Chirp servers. Data is originated from a Chirp server <sourcehost> <sourcepath> and is copied to a given list of Chirp server(s) <host1> <host2> <host3>, etc ...

chirp_distribute is a quick and simple way for replicating a directory from a Chirp server to many Chirp Servers by creating a spanning tree and then transferring data concurrently from host to host using third party transfer. It is faster than manually copying data using parrot cp, chirp_put or chirp_third_put

chirp_distribute also can clean up replicated data using -X option.

OPTIONS

-a, --auth=<flag>
Require this authentication mode.
-d, --debug=<flag>
Enable debugging for this subsystem.
 -D, --info-transfer
Show detailed location, time, and performance of each transfer.
-F, --failures-file=<file>
Write matrix of failures to this file.
-i, --tickets=<files>
Comma-delimited list of tickets to use for authentication.
-N, --copies-max=<num>
Stop after this number of successful copies.
-p, --jobs=<num>
Maximum number of processes to run at once (default=100)
 -R, --randomize-hosts
Randomize order of target hosts given on command line.
-t, --timeout=<time>
Timeout for for each copy. (default is 3600s)
-T, --timeout-all=<time>
Overall timeout for entire distribution. (default is 3600).
 -v, --verbose
Show program version.
 -X, --delete-target
Delete data from all of the target hosts.
 -Y, --info-success
Show confirmation of successful placements.
 -h, --help
Show help text.

ENVIRONMENT VARIABLES

•
CHIRP_CLIENT_TICKETS Comma delimited list of tickets to authenticate with (same as -i).

EXIT STATUS

On success, returns zero. On failure, returns non-zero.

EXAMPLES

To copy a directory from server1 to server2, server3, server4 using chirp_distribute: 
chirp_distribute server1.somewhere.edu /mydata server2.somewhere.edu server3.somewhere.edu server4.somewhere.edu

To replicate a directory from server1 to all available Chirp server(s) in Chirp catalog using chirp_distribute and chirp_status:

chirp_distribute server1.somewhere.edu /mydata `chirp_status -s`

To replicate a directory from server1 to all available Chirp server(s) in Chirp catalog using chirp_distribute and chirp_status. However stop when reach 100 copies with -N option:

chirp_distribute -N 100 server1.somewhere.edu /mydata `chirp_status -s`

To clean up replicated data using chirp_distribute using -X option:

chirp_distribute -X server1.somewhere.edu /mydata `chirp_status -s`
