## DESCRIPTION

This command creates specified number of files of specified size in test directory. The created files will be automatically replicated by gfmd. This command measures creation time of the files.

This command is expected to be called by gfperf.rb in parallel.

## OPTIONS

`-t, --testdir` test directory

  Files are created in test directory. Specify only gfarm url (that begins with gfarm:///) . The default is gfarm:///tmp .

`-m, --gfarm2fs` gfarm2fs mount point

  Specify gfarm2fs mount point.

`-l, --filesize` file size

  File size to be created. The default is 1G. (1G=2^30)

`-f, --number` number of files

  Number of files to be created. The default is 10.

`-r, --replica` number of replica

  Number of replica. The default is 1.

`-s, --stop` wait time

  Wait time in seconds for replication. The default is 60 seconds.

`-n, --name` group name

  Group name in parallel execution.

`-w, --wait` start time

  Start time specified by gfperf.rb. This command waits until start time. Start time is written in UTC (YYYY-MM-DDThh:mm:ssZ) and must be in 10 seconds from current time.
