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>

-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.

ENVIRONMENT VARIABLES¶

•

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

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`
