Suspend and Resume Nodes

This section describes how to suspend and resume nodes in a cluster.

The suspended node state indicates that the node has been intentionally taken offline, for example for maintenance.

The following examples use the confd_client command-line tool in a Linux terminal. For more information, see ConfD.

Suspend a Node

To suspend a node, use the ConfD command node_suspend. For example, to suspend node 12 in the current deployment:

confd_client -c node_suspend -a '{"nid": 12}'

Resume a Node

Starting up a node will automatically unsuspend it. You can also manually unsuspend a node using the ConfD job node_resume. For example:

confd_client -c node_resume -a '{"nid": 12}'
