Description
replay-ost-single test 6 fails with ''space grew after dd: before:X after_dd:Y” for some values of X and Y.
Looking at the suite_log for a recent failure, logs at https://testing.whamcloud.com/test_sets/d53ee48a-665d-11e9-8bb1-52540065bddc , we see
CMD: trevis-45vm9 lctl set_param fail_loc=0x80000119 fail_loc=0x80000119 before: 13442048 after_dd: 13442048 took 20 seconds replay-ost-single test_6: @@@@@@ FAIL: space grew after dd: before:13442048 after_dd:13442048
Some of the failure have the before and after values the same and some failures have different values for before and after.
There are no errors in any of the node console logs.
This failure looks like LU-4265. I’ve opened a new ticket because this test has failed with this error message six times in the past year and a half. Of those six failures, four have been seen this month. Thus, maybe something landed recently that is increasing the frequency of this failure or there a different/new cause.
There are several examples of this failure, but here are just a couple of additional links to logs
