Description

sanity-quota test_61 fails with 'write succeed, expect EDQUOT'. This test seems to fail once or twice a month on master and/or on b2_12 and started in March or earlier of this year.

sanity-quota test 61 fails the following call to the test_default_quota() routine

3274         test_default_quota "-g" "data"

and fails the following code in the test_default_quota() routine

3192         log "Test out of quota"
3193         # flush cache, ensure noquota flag is set on client
3194         cancel_lru_locks osc
3195         cancel_lru_locks mdc
3196         sync; sync_all_data || true
3197         if [ $qpool == "data" ]; then
3198                 $RUNAS $DD of=$TESTFILE count=$((LIMIT*2 >> 10)) oflag=sync &&
3199                         quota_error $qtype $qid "write succeed, expect EDQUOT"

Looking at the client test_log for the failure at https://testing.whamcloud.com/test_sets/1e9bb45a-d2ce-11e9-a25b-52540065bddc, we see

Looking at the console logs, there is nothing obviously wrong and no error messages.
