I didn't do a thorough enough job Googling. Sounds like as long as I bring down the other node (or at least stop gfs2 services), I can then tell the primary node to remount the gfs2 file system with lockproto set to lock_nolock. May give this a shot. Ray -- Linux-cluster mailing list Linux-cluster@redhat.com https://www.redhat.com/mailman/listinfo/linux-cluster
