[Gluster-devel] Support to reclaim locks (posix) provided lkowner & range matches

Hi, 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 cli

Here is a quick way how to test this: GlusterFS 3.7.13 volume with default settings with brick on ZFS dataset. gluster-test1 is server and gluster-test2 is client mounting with FUSE. Writing file with oflag=direct is not ok: [root@gluster-test2 gluster]# dd if=/dev/zero of=file oflag=direct count

I can't tell myself, I'm using the ovirt-4.0-centos-gluster37 repo (from ovirt-release40). I have a second gluster-cluster as storage, I didn't dare to upgrade, as it simply works...not as an ovirt/vm storage.

The point is that even if all other backend storage filesystems do correctly untill 3.7.11 there was no error on ZFS. Something happened nobody ever could explain in the release of 3.7.12 that makes FUSE- mount _in ovirt_ (it partly uses dd with iflag=direct  , using iflag=direct yourself gives als
