If not, the LFSCK should migrate the name entry from current MDT to the right MDT. This should be done with async commit supported from DNE2 to avoid lost the name entry or duplicate the name entry and some other recovery troubles.</p> LU-5550

LFSCK 5: Migrate the name entry from one MDT to another MDT if the name hash does not match the striped directory

Bug Minor Open Unresolved nasf nasf dne3 lfsck Wed, 27 Aug 2014 03:40:17 +0000 Tue, 25 Feb 2020 18:44:08 +0000 Lustre 2.7.0 0 5 <p>This would essentially allow migrating to or from a striped directory, or changing the directory striping arbitrarily, so long as it was clear what the "goal" directory count was, and the directory was marked with <tt>LMV_HASH_FLAG_MIGRATION</tt> so that clients knew to query all of the directory shards when doing a lookup.</p> <p>If crash+bug resulted in the situation described, would current lfsck detect and report the issue, even if it cannot yet repair it?</p> Related LU-4684 Development Rank 1|hzwupz: Rank (Obsolete) 15472 Severity
