Property and resource options

Pacemaker provides options to support cluster configurations from small and simple to and large and complex. The following list identifies the options that support the two-node, active/passive configuration for Control Center.

Keep all resources bound to the same host.
Pacemaker supports the notion of a voting quorum for clusters of three or more nodes. However, with just two nodes, if one fails, it does not make sense to have a quorum of one, therefore we disable quorums.

Fence or isolate a failed node. (The string "stonith" is an acronym for "shoot the other node in the head".) This option should only be set to true when fencing is implemented. For more information about fencing, see Planning a high-availability deployment.

If fencing is implemented, set this option to false during the initial setup and testing period. For production use, set it to true.
