[LU-16336] LFSCK should fix inconsistencies caused by recovery abort

• Type: Bug
• Resolution: Unresolved
• Priority: Major
• Affects Version/s: Lustre 2.16.0
• Severity: 3
• Assignee: Lai Siyao
• Reporter: Lai Siyao

Description

In LU-16159, the update logs are canceled upon recovery, which will cause inconsistencies in the filesystem. LFSCK should be able to fix these inconsistencies.

This is visible in tests like replay-single test_70b that sometimes leave an undeletable directory behind after test completion (LU-10616). There are various workarounds (e.g. LU-16335 to use "lfs rm_entry" to unlink the directory from the namespace, or EX-6692 to reformat the filesystem), but it would be much better to have LFSCK fix these directories and/or allow them to actually be unlinked from the filesystem.
