Overview of Commands
The Serviceguard and OCFS2 environment includes a set of commands for simplifying the process
of creating, configuring and applying various packages that are required for running OCFS2
with HP Serviceguard for Linux.
Following are the commands that are explained in subsequent sections:
• ocfs2cluster
• ocfsmntadm
Using the ocfs2cluster Command
Use the ocfs2cluster command to complete one or all of the following tasks:
• Create, configure and apply an OCFS2 system multi-node package.
• Remove an already configured OCFS2 system multi-node package.
• Start or stop an OCFS2 system multi-node package.
• View the command help.
Following examples illustrate how to use the ocfs2cluster command to complete each of the
tasks.
To create, configure and apply an OCFS2 system multi-node package, run the following
commands:
# ocfs2cluster config [--heartbeat_threshold <timeout>]\
[--idle_timeout_ms <timeout>] [--reconnect_delay_ms <timeout>]\
[--keepalive_delay_ms <timeout>] [-s]
Following is the output that is displayed if you create and configure a system multi-node package
with the default values:
# ocfs2cluster config -s
