fenced(8) man page.

3. Multicast tab — This tab provides an interface for configuring these Multicast

Configuration parameters: Let cluster choose the multicast address and Specify the

multicast address manually. Red Hat Cluster software chooses a multicast address for

cluster management communication among cluster nodes; therefore, the default setting is

Let cluster choose the multicast address. If you need to use a specific multicast address,

click Specify the multicast address manually, enter a multicast address into the text box,

and click Apply for changes to take effect.

4. Quorum Partition tab — This tab provides an interface for configuring these Quorum

Partition Configuration parameters: Do not use a Quorum Partition, Use a Quorum

Partition, Interval, Votes, TKO, Minimum Score, Device, Label, and Heuristics. The Do

not use a Quorum Partition parameter is enabled by default. Table 3.1, “Quorum-Disk

Parameters” describes the parameters. If you need to use a quorum disk, click Use a

Quorum Partition, enter quorum disk parameters, click Apply, and restart the cluster for the

changes to take effect.

Important

Quorum-disk parameters and heuristics depend on the site environment and the

special requirements needed. To understand the use of quorum-disk parameters

and heuristics, refer to the qdisk(5) man page. If you require assistance

understanding and using quorum disk, contact an authorized Red Hat support

representative.

Note

Clicking Apply on the Quorum Partition tab propagates changes to the cluster

configuration file (/etc/cluster/cluster.conf) in each cluster node. However,

for the quorum disk to operate, you must restart the cluster (refer to Section 1,

“Starting, Stopping, and Deleting Clusters”).
