[LU-13524] lfs hsm_* commands do not continue on error properly

• Status: Open
• Project: Lustre
• Type: Bug
• Priority: Minor
• Reporter: John Hammond
• Assignee: WC Triage
• Resolution: Unresolved
• Severity: 3

Description

When given multiple files the lfs hsm_* commands stop on the file that generates and error and do not process the remaining arguments. This is not the expected behavior of a unix/linux utility. The expected behavior is to report the error, continue with the remaining files, and exit with a non zero status. Following the expected behavior makes these commands much more useful when used in scripts or by hand.

k:lustre# echo XXX | tee f{1,2,3}

Cannot stat f0: No such file or directory
k:lustre# lfs hsm_state f{0..3}
