If you just want to access the data, IIRC you should be able to simply do vgchange -cn VG_name (turn off cluster locking for that VG. See "man vgchange"). Then (possibly) "pvscan;vgchange -ay" If you also have some gfs/gfs2 filesystem, you should be able to mount them with "-o lock_nolock" -- Fajar -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
