One of the bugs since then was solved by a change in the VFS so that its not just a question of applying patches to gfs2 on its own. The version of GFS2 in RHEL has a different fix for this problem though, so you might be able to borrow that. Either way its not going to be an easy task and using a more recent kernel would be a much quicker way of getting a more stable GFS2, Steve. > -- > Linux-cluster mailing list > Linux-cluster@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
