Subject: LU-13709 tests: test lfs mkdir -c without -i
X-Git-Tag: 2.13.57~74
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=2c89cc6c25549cb6748c7c9f5a209c7e38387eb4

LU-13709 tests: test lfs mkdir -c without -i

Almost every test with lfs mkdir -c in the test suite also
uses option -i, so lfs mkdir -c (same as -i -1, where lustre
chooses the MDTs) is poorly tested.  Add a test for that
case, sanity test_300s.
