[Ocfs2-devel] [Ocfs2-users] How to unlock a bloked resource? Thanks

[Sunil Mushran]

What is the output of the commands? The protocol is supposed to do the
unlocking on its own. See what is it blocked on. It could be that the node
that has the lock cannot unlock it because it cannot flush the journal to
disk.
