5.7. Accessing Cluster Tools from a Remote Node
Besides allowing the cluster to manage resources on a remote node, pacemaker_remote has one other trick. The pacemaker_remote daemon allows nearly all the pacemaker tools (crm_resource
, crm_mon
, crm_attribute
, crm_master
, etc.) to work on remote nodes natively.
Try it: Run crm_mon
on the remote node after pacemaker has integrated it into the cluster. These tools just work. These means resource agents such as master/slave resources which need access to tools like crm_master
work seamlessly on the remote nodes.
Higher-level command shells such as pcs
may have partial support on remote nodes, but it is recommended to run them from a cluster node.
