Lock file on non-glusterfs-volume is taken for ever by glusterfs fuse after reboot

[kripper]

Description of problem:

Lock file on non-glusterfs-volume is taken for ever by glusterfs fuse after forced reboot.

The exact command to reproduce the issue:

Used flock() from PHP on /tmp/test.lock which is not a glusterfs. After forced reboot (power failure) the lock file is taken for ever by this process:

/usr/sbin/glusterfs --process-name fuse --volfile-server=myvol --volfile-id=myvol /mnt/myvol

This problem has been there for over 8 years.

It's very easy to reproduce.

Expected results:

Lock should be released after reboot. And maybe not taken by glusterfs if it's not a glusterfs volume.
