[Test][Bug]Test to check directory gfid mismatch per BZ#1661258
Testcase steps: 1. Create a volume and mount it. 2. Create a directory on mount and check whether all the bricks have the same gfid. 3. Now delete gfid attr from all but one backend bricks, 4. Do lookup from the mount. 5. Check whether all the bricks have the same gfid assigned. Failing in CentOS-CI due to the following bug: https://bugzilla.redhat.com/show_bug.cgi?id=1696075 Change-Id: I4eebc247b15c488cfa24599e0afec2fa5671656f Co-authored-by: Anees Patel <anepatel@redhat.com> Signed-off-by: Anees Patel <anepatel@redhat.com> Signed-off-by: kshithijiyer <kshithij.ki@gmail.com>
