Viewing the cluster state

Operating system based

There are multiple operating system commands that can be run as root or as a user with appropriate permissions. The commands enable you to get an overview of the status of the cluster and its services.

# pcs status --full

Note: Omit the --full for a more concise output if you do not need to view the node attributes.
