            That may be related with the system schedule order: if the OI scrub run faster, and it could has already repaired the invalid OI mapping for the remote directory object before related RPC handler to call osd_fid_lookup() to locate such remote directory object.

            It is introduced by the patch http://review.whamcloud.com/#/c/16951/. But related failure under such patch has never been triggered before.

            It looks like this is related to the landing of one of the patches:

            It would be worthwhile to investigate if this problem hit on either of those patches before landing?

            adilger Andreas Dilger added a comment - It looks like this is related to the landing of one of the patches: http://review.whamcloud.com/18175 " LU-7302 scrub: join the running OI scrub properly" http://review.whamcloud.com/16951 " LU-6861 scrub: only trigger full OI scrub when necessary" It would be worthwhile to investigate if this problem hit on either of those patches before landing?

            Is there any explanation why this started failing? Is it due to some patch being landed that had a bug? If yes, did that patch also fail testing, but this problem was missed?
