seems to be a bit more complicated than expected:

Error: '/mnt/lustre/d61a.sanity-flr/f61a.sanity-flr: atime: old '1712819228' != new '1712819221''

[Alex Zhuravlev]

Doh! Can you try adding a longer sleep into the test, so that atime is updated?

sure

Test-Parameters: trivial testlist=sanity env=ONLY=61a,ONLY_REPEAT=100 clientdistro=el9.3

just noticed the testing patch asked for sanity, not sanity-flr

Error: '/mnt/lustre/d61a.sanity-flr/f61a.sanity-flr: atime: old '1712732591' != new '1712732585''
