14.1.5 Management Utilities and Commands

OCFS2 stores parameter files specific to the node on the node. The cluster configuration
file (/etc/ocfs2/cluster.conf) resides on each node assigned to the cluster.
The ocfs2console utility is a GTK GUI-based interface for managing the configu-
ration of the OCFS2 services in the cluster. Use this utility to set up and save the /etc/
ocfs2/cluster.conf file to all member nodes of the cluster. In addition, you can
use it to format, tune, mount, and umount OCFS2 volumes.
Additional OCFS2 utilities are described in the following table. For information about
syntax for these commands, see their man pages.
