 Description   

sanity test_230q fails with 'stripe hash crush,migrating != crush' for DNE/ZFS testing starting on 12 June 2020.

For the recent failure at https://testing.whamcloud.com/test_sets/4660852d-f9fc-4083-bf33-cecf0dcfdf7e, the client test_log shows the test waiting for ‘lfs getdirstripe -H’ to return crush, but gets ‘crush.migrating’ and times out

Update not seen after 200s: want 'crush' got 'crush,migrating'
 sanity test_230q: @@@@@@ FAIL: stripe hash crush,migrating != crush

There is nothing obviously wrong looking at the console and dmesg logs.

I don't see anything wrong in the logs, it looks to be slow ZFS again. I'll update the test script to test with fewer files.
