 Description   

This issue was created by maloo for Vladimir Saveliev <c17830@cray.com>

This issue relates to the following test suite run: https://testing.whamcloud.com/test_sets/6bf04d76-1386-4340-9901-b90a0ff7e8c5

test_56oc failed with the following error:

'/usr/bin/lfs find /mnt/lustre/d56oc.sanity ! -neweram /mnt/lustre/f56oc.sanity.negnewer.am' wrong: found 12, expected 16

Other instances:
https://testing.whamcloud.com/sub_tests/f4481298-9466-480f-81c3-f1ad681000d3 - this has most similar signature:

/usr/bin/lfs find /mnt/lustre/d56oc.sanity -neweram /mnt/lustre/f56oc.sanity.newer.am ! -neweram /mnt/lustre/f56oc.sanity.negnewer.am' wrong: found 12, expected 16

There are many other failures of sanity test_56oc. The most frequently they have:

/usr/bin/lfs find /mnt/lustre/d56oc.sanity -newerbt 2020-10-02 03:25:39' wrong: found 0, expected 16

LU-13665 attributes these failures to interop, however in https://testing.whamcloud.com/test_sets/6bf04d76-1386-4340-9901-b90a0ff7e8c5 there were 2.13.55.1 on clients and servers,
in https://testing.whamcloud.com/sub_tests/f4481298-9466-480f-81c3-f1ad681000d3 - 2.13.56.1 everywhere.

Recent incidences of this failure are likely due to LU-11912.
