Description

The patch for LU-6562 at http://review.whamcloud.com/#/c/14660/ corrected sanity-scrub tests 4a, 4b, and 4c to correctly look for the ‘prior updated’ parameter in the OI scrub output. Correcting this triggered a failure, printing the values of prior_updated before (updated0) and after the scrub_check_* routines and, for 4b,, we see:

updated0[1] = 3
updated0[2] = 0
updated0[3] = 0
updated0[4] = 0
updated1[1] = 4
updated1[2] = 0
sanity-scrub test_4b: @@@@@@ FAIL: (12) Auto trigger full scrub unexpectedly 

From the comments in LU-6562, this output is unexpected.

I think the recent failures listed above are due to LU-8416 and not this ticket; the error messages are the same, but the test logs look different.

[Andreas Dilger]

Closing this ticket after patch was landed, LU-8416 should be used for the new sanity-scrub 4b/4c failures.
