3 lfs \- Lustre utility to create a file with specific striping pattern, find the striping pattern of exiting files
8 .B lfs find [--obd <uuid>] [--quiet | --verbose] [--recursive] <dir|file>
10 .B lfs getstripe <file-name>
12 .B lfs setstripe <filename> <stripe-size> <start-ost> <stripe-cnt>
15 can be used to create a new file with a specific striping pattern, determine the default striping pattern, gather the extended attributes (object numbers and
16 location) for a specific file. It can be invoked interactively without any
17 arguments or in a non-interactive mode with one of the arguements supported.
19 The various options supported by lctl are listed and explained below:
22 To create a new file with a specific striping pattern
25 To list the extended attributes for a given filename or files in a directory or recursively for all files in a directory tree. It can also be used to list the files that have objects on a specific OST.
28 To list the striping pattern for given filename
31 Provides brief help on the various arguments
