osd/scrub: discard repair_oinfo_oid()#61590
Merged
Conversation
repair_oinfo_oid(), called every scrub, has a very specific functionality: fix the object ID specified in the Object Info attribute, if different from the ID of the owning object. This fix was added in 2017, as a response to a unique failure scenario that was observed in Sepia - probably following a filesystem bug. See https://tracker.ceph.com/issues/18409 & https://tracker.ceph.com/issues/20471. The limited functionality of repair_oinfo_oid() - only repairing this one specific issue, and only if the OI_ATTR exists and is decodable - does not justify the overhead of running it every scrub.
