4.3.5. Accessing Cluster Tools from Guest Node
Besides allowing the cluster to manage resources on a guest 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 guest nodes natively.
Try it: Run crm_mon
on the guest after pacemaker has integrated the guest node into the cluster. These tools just work. This means resource agents such as master/slave resources which need access to tools like crm_master
work seamlessly on the guest nodes.
Higher-level command shells such as pcs
may have partial support on guest nodes, but it is recommended to run them from a cluster node.
