If the Deatch tier has failed(for whatever reason, in this case the failure of removal of xattr) in the beginning that mean definitely files are not migrated to COLD. So Wont this be a redundant bug. Suggestion : 1. Either we close this bug saying it deduplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1332957, and update 1332957 saying files are not still in hot. 2. Or Change the title/summary of 1334234 saying files detach tier failed due to failure of removal of xattr, hence files are still there in hot. Because the title now may be misleading saying "Files remain in hot tier even after detach tier completes", giving the impression on a sunny day, where detach tier is fine, files are still in HOT. Also make this bug depends on 1332957. Oops My bad! you are correct. We do it at the end of detach tier start i.e by then file would have been move. This is not a redundant bug. We should have files moved to cold. Patch posted upstream : review.gluster.org/#/c/14285/ RCA: Previously we had wrongly placed the clearing tier-fix-layout-complete xattr before the joining of migration threads. This would lead to situations where failure of clearing the xattr would cause the premature death of migration threads. Fix: Now we clear the xattr only after the data movement threads join, ensuring that all migration is done. Downstream patch : https://code.engineering.redhat.com/gerrit/#/c/74382/ The issue reported in the bug is no more seen in build - glusterfs-3.7.9-5. Detach tier completes successfully and migrates all files to cold tier. Moving the bug to verified.
