[LU-18579] lfs_migrate script does not preserve OST pool if unspecified

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.17.0
• Affects Version/s: Lustre 2.14.0, Lustre 2.16.1
• Severity: 3
• Assignee: Andreas Dilger

Description

It appears that if "lfs_migrate FILE" is run without specifying an OST pool, then the existing pool that a file is allocated on is lost, due to a bug in the script. Running the "lfs migrate" command without any arguments does not lose the pool, but if some other argument is passed (e.g. "-c 2") then the OST pool in the layout is also lost.

This can cause file objects to be allocated on the wrong OSTs during a mass migration.
