Description

We faced multiple missing OST objects mdtest job failure during failover/failback test(stripe count 2).

V-1: Entering unique_dir_access...
V-1: Entering mdtest_stat...
08/14/2018 21:46:25: Process 25(nid00016): FAILED in mdtest_stat, unable to stat file: No such file or directory
08/14/2018 21:46:25: Process 30(nid00045): FAILED in mdtest_stat, unable to stat file: No such file or directory

Failure occurred because of absent the range of objects on one of the OSTs.

The marker of the failure could be the following message after recovery on OST:

Aug 14 21:46:07 snx11205n004 kernel: format at ofd_dev.c:1713:ofd_create_hdl doesn't end in newline
