Description

sanity test 65i is failing for DNE with ZFS configurations. Looking at the client test log at https://testing.whamcloud.com/test_sets/4ac91f66-e875-11e8-bfe1-52540065bddc , we see ‘lfs find’ is failing with

lfs find: llapi_semantic_traverse: Failed to open '/mnt/lustre/d60g.sanity/subdir2': No such file or directory (2)
error: find failed for /mnt/lustre.
 sanity test_65i: @@@@@@ FAIL: find /mnt/lustre failed 

Looking at the console logs, the only indication of a problem is in the client (vm7) console
