the in-kernel node manager, and communicates the
resource used for the heartbeat to the in-kernel
heartbeat thread

wide locks on resources to the in-kernel distributed
lock manager that keeps track of all locks and their
owners and status

13.1.5 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.
IMPORTANT
The file browser column in the ocfs2console utility is prohibitively slow and
inconsistent across the cluster. We recommend that you use the ls(1) com-
mand to list files instead.
Additional OCFS2 utilities are described in the following table. For information about
syntax for these commands, see their man pages.
