Description Sakshi 2015-09-14 09:25:06 UTC

Description of problem:
DHT: mount hangs when directories are created and deleted continuously from multiple mounts

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Create a dist-rep volume
2.Create and delete directories continuously from mount
3.Perform step 2 parallely from multiple mounts (say 4)

Actual results:
One or more mount hangs after sometime

Expected results:
Mount should not hang

Additional info:
Due to existing race between rmdir/selfheal, sometimes directories end up having gfid mismatch. Hence AFR may unlock on different gfid and not on the one it locked initially thereby blocking another client.
