[LU-12066] recovery-small test 26b fails with “Client was not evicted by ost rc=1”

Related — Wed, 7 Feb 2024 19:54:04 +0000

recovery-small test_26b fails with “Client was not evicted by ost rc=1”. We only see this issue with failover testing

Looking at a recent failure at https://testing.whamcloud.com/test_sets/e21fbf5e-4500-11e9-9720-52540065bddc , in the suite_log, we see an error at the beginning of the test

On client 1 (vm1) we see an error in the console logs

There’s nothing obviously wrong looking at the rest of the console logs.

We see a similar failure with master failover testing, but the logs do not have the ll_inode_revalidate_fini() error in the client console log and don’t have the ‘invalid path’ error. In some cases, recovery-small test 26a fails before the 26b failure.
