Using xfstests I was able to trigger dlm issues in ocfs2.
I ran xfstests on one node and other nodes had it mounted too.
To ensure that fsck.ocfs2 will not corrupt the filesystem I've applied
If you don't like the patch I'm perfectly fine with that.
Maybe it makes more sense to add a feature to xfstests which unmounts
the ocfs2 filesystem on all nodes (using SSH), then it is allowed to
