[LU-11774] replay-single test 0c fails with ‘mount fails’

Fri, 9 Apr 2021 17:28:29 +0000

replay-singe test_0c fails with ‘mount fails’.

Looking at a recent failure, https://testing.whamcloud.com/test_sets/5532dea2-fd87-11e8-93ea-52540065bddc , we can see in the client test_log that there is a problem unmounting the file system because it is busy and then failover MDS1 (vm9)

CMD: trevis-9vm9 /usr/sbin/lctl mark mds1 REPLAY BARRIER on lustre-MDT0000
umount: /mnt/lustre: target is busy
        (In some cases useful info about processes that
         use the device is found by lsof(8) or fuser(1).)
Failing mds1 on trevis-9vm9

Then we see that the file system fails to mount because it is already mouted

CMD: trevis-9vm6 mkdir -p /mnt/lustre
CMD: trevis-9vm6 mount -t lustre -o user_xattr,flock trevis-9vm9@tcp:/lustre /mnt/lustre
mount.lustre: according to /etc/mtab trevis-9vm9@tcp:/lustre is already mounted on /mnt/lustre
 replay-single test_0c: @@@@@@ FAIL: mount fails

It’s possible that the file system never unmounted.

replay-single test_0d always fails after 0c and in the same way.

Looking over all branches for the past year, this test started to fail on July 31, 2018.
