Description

This issue was created by maloo for Andreas Dilger <[e-mail]>

This issue relates to the following test suite run: https://testing.whamcloud.com/test_sets/01323587-3a6c-4307-8adc-27c3a5d505a4

test_27M failed with the following error:

CMD: trevis-99vm4,trevis-99vm5 /usr/sbin/lctl set_param mdd.*.append_stripe_count=-1

 sanity test_27M: @@@@@@ FAIL: (5) stripe count , should be 8 for append 

At first glance this looks like a bug in the script where the stripe_count of -1 is causing a parsing error, but looking at the debug log it seems that the creation of f27M.sanity.5 failed. There are no messages on the console of the client or either MDS.

The test first failed this way on 2022-08-09 on a patch that was landed on 2022-08-31, but there was a similar failure on 2022-08-18, so it is unlikely the original failure was caused by that patch.

The client showed an -22 = -EINVAL error returned from the MDS for the create:

but there isn't really any useful information in the MDS debug log (too low debug level, only dlmtrace enabled).
