+++ This bug was initially created as a clone of Bug #1262408 +++ Description of problem: ========================= When we have many files, say about 5000 files in hot tier, and when detach tier is issued, we can see many files as failed in detach tier status, in this case about 2000 files. But all files are migrated, if we check the backend bricks. So, is this spurious errors or a serious miss?

But it can also be seen many failures [root@zod glusterfs]# gluster v detach-tier vol100 status Node Rebalanced-files size scanned failures skipped status run time in secs --------- ----------- ----------- ----------- ----------- ----------- ------------ -------------- localhost 0 0Bytes 0 0 0 in progress 0.00 yarrow 0 0Bytes 0 0 0 in progress 0.00 [root@zod glusterfs]# gluster v detach-tier vol100 status Node Rebalanced-files size scanned failures skipped status run time in secs --------- ----------- ----------- ----------- ----------- ----------- ------------ -------------- localhost 1157 2.5GB 4736 1814 0 completed 98.00 yarrow 1897 526.1MB 3056 1156 0 completed 97.00
