Major Description
replay-single test_80g fails for ZFS with DNE Lustre configurations. Looking at a recent failure, https://testing.whamcloud.com/test_sets/6c06f67c-cf6a-11e8-82f2-52540065bddc , we see ‘lfs getstripe’ fails

Comparing the console log from this failed test session to one where test 80g passes, we see a few errors in the MDS2, MDS4 (vm10) log:

This test fails almost 100% of the time for a DNE wth ZFS configuration. Frequently, replay-single test 80g fails after test 80f fails, but this is not always true.
