44 Chapter 3. Installing and Configuring Red Hat Cluster Suite Software
Tip
Choose the cluster name carefully. The only way to change the name of a Red Hat
cluster is to create a new cluster configuration with the new name.
4. (Optional) The Config Version value is set to
1
by default and is automatically
incremented each time you save your cluster configuration. However, if you need to
set it to another value, you can specify it at the
Config Version
text box.
5. Specify the
Fence Daemon Properties
parameters:
Post-Join Delay
and
Post-Fail
Delay
.
a. The
Post-Join Delay
parameter is the number of seconds the fence daemon
(
fenced
) waits before fencing a node after the node joins the fence domain.
The Post-Join Delay default value is
3
. A typical setting for Post-Join Delay
is between 20 and 30 seconds, but can vary according to cluster and network
performance.
b. The
Post-Fail Delay
parameter is the number of seconds the fence daemon
(
fenced
) waits before fencing a node (a member of the fence domain) after
the node has failed. The
Post-Fail Delay
default value is
0
. Its value may be
varied to suit cluster and network performance.
Note
For more information about Post-Join Delay and Post-Fail Delay , refer to the
fenced(8) man page.
6. Save cluster configuration changes by selecting
File
=>
Save
.
