Cluster maintenance mode options

When a cluster is in maintenance mode, the cluster does not start or stop any services until told otherwise. When maintenance mode is completed, the cluster does a sanity check of the current state of any services, and then stops or starts any that need it.

To put a cluster in maintenance mode, use the following command to set the maintenance-mode cluster property to true.

# pcs property set maintenance-mode=true

To remove a cluster from maintenance mode, use the following command to set the maintenance-mode cluster property to false.

# pcs property set maintenance-mode=false
