After all the tests in sanity-lfsck run, the suite hangs at umount for /mnt/mds4. All subtests are marked as PASS. Logs are at https://testing.hpdd.intel.com/test_sets/fb298f72-6a05-11e5-9d0a-5254006e85c2 In the suite_stdout log, the last thing we see is 13:48:04:CMD: shadow-23vm8 grep -c /mnt/mds4' ' /proc/mounts 13:48:04:Stopping /mnt/mds4 (opts:-f) on shadow-23vm8 13:48:04:CMD: shadow-23vm8 umount -d -f /mnt/mds4 14:47:53:********** Timeout by autotest system ********** Looking at the logs for the last test run, sanity-lfsck test_31h, it’s clear that something is not functioning correctly. What went wrong isn’t that clear to me. From the MDS2, 3, 4 console, it’s clear there’s problems communicating between the MDTs more than normal for this test: 14:23:44:Lustre: lustre-MDT0003: Not available for connect from 10.1.5.32@tcp (stopping) 14:23:44:Lustre: Skipped 226 previous similar messages 14:23:44:LustreError: 137-5: lustre-MDT0001_UUID: not available for connect from 10.1.5.32@tcp (no target).
