That's not possible; you must reboot the node to clear it. The problem is caused when gfs_controld dies or is killed while gfs2 is still mounted. This leaves an orphaned/uncontrolled gfs2 fs in the kernel (the same also applies to dlm). The machine must be rebooted to clear it. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
