Description

With MDSCOUNT=2, sanity test 31f will fail when the test creates a directory using 'lfs setdirstripe -i 1' but then tries to remove it using 'rm -r'. A test_rmdir function could be added to test-framework.sh to handle this case.

Issue Links

• duplicates: LU-2240 implement index range lookup for osd-zfs.
• duplicates: LU-2754 rename from MDT1 to MDT0 sometimes appears to succeed but does not
• is related to: LU-2755 calling rmdir on remote directory returns -ENOENT instead of -EBUSY

Closing this as a duplicate of LU-2754, since the symptoms are similar, and they will be fixed by the same patch.

This can be fixed by http://review.whamcloud.com/#change,5257 as well.

John, it would also be good to create new test cases if there is testing that you are doing by hand that is not being caught by existing regression tests.

Deleting a remote directory should work fine with "rm -r" or "rmdir", and should not need any special handling in userspace.

I think this is related to LU-2755, and there should NOT be special handling of deleting remote entries.
