Edit Cluster Nodes
Use the information provided in this topic to edit cluster nodes.
Add a Node
You can edit an existing and operational Paragon Automation cluster and add additional nodes to the cluster. The node can be either a primary or worker node.
However, note that if your existing cluster is configured with a single primary node, you cannot add an additional primary node using this procedure. To add an additional primary node to a single primary node cluster, you must reinstall the whole cluster.
To add new node(s):
Remove a Node
You can edit an existing and operational Paragon Automation cluster to remove one or more nodes from the cluster.
To remove node(s):
Replace a Node
You can replace a node with another node in an existing Paragon Automation cluster.
To replace a node with another node:
In some cases, if a node fails, you can rebuild a replacement node using the same IP address as the failed node.
To redeploy the same node as a replacement, perform the following steps:
Prepare the node and ensure it meets all the cluster node prerequisites as described in Prepare Cluster Nodes.
Log in to the control host.
Execute the
./run -c config-dir deploy
command again.You can also limit the execution of the command to only the redeployed node by using the
./run -c config-dir deploy -l node-address
command.
