Description

sanity test_27I (capital i) fails with “multiop failed” when run with the latest 2.12 servers and master (2.13.0) clients. Looking at the client test_log, we see

Updated after 3s: wanted 'lustre-OST0001_UUID ' got 'lustre-OST0001_UUID '
open(O_RDWR|O_CREAT): Invalid argument
 sanity test_27I: @@@@@@ FAIL: multiop failed 

It looks like this test was added in Lustre version 2.12.53 with patch https://review.whamcloud.com/#/c/34386/ . This sanity test needs a version check and should be skipped for Lustre servers with version less than 2.12.53.
