    Description

      The last lines seen in the suite_log are of successfully unmounting all MDTs and then trying to unmount the first OST

      Stopping /mnt/lustre-mds4 (opts:-f) on trevis-41vm5
CMD: trevis-41vm5 umount -d -f /mnt/lustre-mds4
CMD: trevis-41vm5 lsmod | grep lnet > /dev/null &&
lctl dl | grep ' ST ' || true
CMD: trevis-41vm3 grep -c /mnt/lustre-ost1' ' /proc/mounts || true
Stopping /mnt/lustre-ost1 (opts:-f) on trevis-41vm3
CMD: trevis-41vm3 umount -d -f /mnt/lustre-ost1

      Looking at the OSS (vm3) console log, we see some errors

      In the past four months, we’ve seen runtests test_1 hangs on OST unmount three times
      2.12.4 - https://testing.whamcloud.com/test_sets/e7093746-18bf-11ea-9487-52540065bddc

      The following two hangs do not have the “enqueue global quota lock” error messages in the OSS console log
      2.12.57.50 - https://testing.whamcloud.com/test_sets/b9d44252-cf7c-11e9-9fc9-52540065bddc
