Description krishnan parthasarathi 2012-02-13 06:38:09 UTC 
Description of problem:
Need a mechanism accessible to (glusterfs) administrator to clear locks held on an inode. The locks include posix locks and gluster-internal locks.
This feature attempts to mitigate deadlocks/stale-lock situation without a complete restart of the volume.

Comment 5 Raghavendra Bhat 2012-05-24 10:00:23 UTC 
gluster volume clear-locks
Usage: volume clear-locks <VOLNAME> <path> kind {blocked|granted|all}{inode [range]|entry [basename]|posix [range]}


With the above command the locks on a inode (by giving the path) can be cleared.
