Bug Minor Resolved Cannot Reproduce Emoly Liu Maloo zfs Fri, 20 Jun 2014 06:43:54 +0000 Tue, 17 Mar 2020 03:25:45 +0000 Tue, 17 Mar 2020 03:25:45 +0000 Lustre 2.6.0 0 4 <p>It looks like this is a test script problem. It looks like the client was evicted from the MDS during test_26b, when it should have been evicted during test_26a. That caused the test to fail early in test_26b. It seems that test_26a() needs to set fail_loc=0 and then wait to ensure that the client is reconnected to all of the servers.</p> <p>Closing old bug not seen in a long time.</p> Development Rank 1|hzwpkf: Rank (Obsolete) 14599 Severity
