After stopping DRBD, wipefs /dev/vg1/lv1 should list the signatures on the device. Removing *only* the DRBD signature will give a filesystem accessible directly on /dev/vg1/lv1. Make sure to use the --backup option. -- Valentin _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
