Description

This issue was created by maloo for Andreas Dilger <[e-mail]>

This issue relates to the following test suite run:
https://testing.whamcloud.com/test_sets/0109704a-3fe0-446d-bb20-682162328694

test_56ob failed with the following error:

'/usr/bin/lfs find /mnt/lustre/d56ob.sanity -mtime 2w' wrong: found 0, expected 1

Test session details:
clients: https://build.whamcloud.com/job/lustre-reviews/123340 - 5.14.0-503.40.1.el9_5.aarch64+64k
servers: https://build.whamcloud.com/job/lustre-reviews/123340 - 4.18.0-553.89.1.el8_lustre.x86_64

This is failing several times per week, with different time ranges (e.g. -mtime 1d, -mtime 4h, -mtime -1y) so it doesn't appear to be a small race with the timestamps, but something more fundamental like not finding files at all, or the timestamps not being set correctly.  The problem happens exclusively on aarch64 or aarch64+64k clients.  There are some other failures of test_56ob on x86_64 clients but they are caused by unrelated problems in the patches being tested (errors creating files or setting timestamps).
