Bug #56532

client stalls during vstart_runner test
Added by Milind Changire almost 2 years ago.
Updated 12 months ago.
Description
client logs show following message:
failed to remount (to trim kernel dentries): return code = 32
Although, this behavior is seen with my PR: https://github.com/ceph/ceph/pull/44359, this needs to be confirmed whether the new test load (qa/tasks/cephfs/test_uninlining.py) causes the same behavior without the mds side changes i.e. does this behavior manifest on main branch as well
This behavior is seen with fuse-client.
From Milind's reproducing logs, there has two different error code, which are 1 and 32:
$ grep 'to trim kernel dentries' client.* -rn
client.0.774355.log:98:2022-07-14T14:24:03.984+0530 7fbbd5ffb640 -1 client.4495 failed to remount (to trim kernel dentries): return code = 1

When mounting the ceph-fuse it will create a test dentry thread, which will do the remount test in parallel.
