Description

The patch for LU-8411, https://review.whamcloud.com/#/c/21398/, contains the comment

This patch causes sanity test 407 to fail or has brought out an
existing bug in Lustre. sanity test 407 is added to the
ALWAYS_EXCPET list.

Yet, I can’t find any JIRA ticket opened to capture this failure. So, here it is.

sanity test 407 does not fail, but any test that follows it that tries to clean out the test directory will fail. For example, test_409 fails when test 407 is removed from the ALWAYS_EXCEPT list; logs at https://testing.hpdd.intel.com/test_sets/01353734-7efb-11e7-bbc6-5254006e85c2. Test 409 fails with

== sanity test 409: Large amount of cross-MDTs hard links on the same file =========================== 20:11:29 (1502482289)
rm: cannot remove '/mnt/lustre/d407.sanity.1': Directory not empty
 sanity test_409: @@@@@@ FAIL: Fail to cleanup the env! 

when it calls check_mount_and_prep().

In another case, the test suite fails when it tries to clean up the contents of the mount point:

== sanity test complete, duration 6743 sec =========================================================== 01:13:50 (1480986830)
rm: cannot remove '/mnt/lustre/d407.sanity.1': Directory not empty
 sanity : @@@@@@ FAIL: remove sub-test dirs failed 

Logs for this case are at
