Here are a couple things you could try. - Try mounting one fs at a time and seeing if there's problems with just one of them, or all, or only when there's more than one fs mounted... - Shut down the cluster and have just a single node mount each fs using lock_nolock: mount -t gfs /dev/foo /gfs -o lockproto=lock_nolock This mounts the fs as a local file system, so make sure you don't have other nodes mounting the fs! Once it's mounted like this, see if you can access the fs normally. > I see a lot of gfs_recoverd and dlm_recoverd processes running. Do these > have something to do with it? Those will be running all the time. Dave -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
