Lustre 1.6 Operations Manual

Option
Description
help
Provides brief help on various lfs arguments.
exit/quit
Quits the interactive lfs session.
* The default stripe-size is 0. The default stripe-start is -1. Do NOT confuse them! If you set stripe-start to 0, all
new file creations occur on OST 0 (seldom a good idea).
† The file cannot exist prior to using setstripe. A directory must exist prior to using setstripe.
‡ The old setquota interface is supported, but it may be removed in a future Lustre release.
Examples
$ lfs setstripe -s 128k -c 2 /mnt/lustre/file
Creates a file striped on two OSTs with 128 KB on each stripe.
$ lfs setstripe -d /mnt/lustre/dir
Deletes a default stripe pattern on a given directory. New files will use the default
striping pattern.
$ lfs setstripe --pool my_pool /mnt/lustre/dir
Associates a directory with the pool my_pool, so all new files and directories are
created in the pool.
$ lfs setstripe --pool my_pool -c 2 /mnt/lustre/file
Creates a file striped on two OSTs from the pool my_pool
$ lfs pool_list /mnt/lustre/
Lists the pools defined for the mounted Lustre filesystem /mnt/lustre
$ lfs pool_list my_fs.my_pool
Lists the OSTs which are members of the pool my_pool in filesystem my_fs
$ lfs getstripe -v /mnt/lustre/file1
