Description Soumya Koduri 2016-07-22 12:22:27 UTC
Description of problem:

In certain scenarios (esp.,in highly available environments), the application may have to fail-over/connect to a different glusterFS client while the I/O is happening. In such cases until there is a ping timer expiry and glusterFS server cleans up the locks held by the older glusterFS client, the application will not be able to reclaim their lost locks. To avoid that we need support in Gluster to let clients reclaim the existing locks provided lkwoner matches.
