"You are going to uninventory at least one resource that may be used by the storage cluster"

Environment

• Red Hat JBoss Operations Network (JON)
  • 3.2
  • 3.3

Issue

• While removing agent getting below warning:

"You are going to uninventory at least one resource that may be used by the storage cluster. To avoid any errors in the future, you should run undeploy the node prior to the this step. Do you really want to continue on your own risk?" and continue?

• JON Inventory tells a platform is part of storage cluster when it is not.
• Every time I want remove a platform from inventory I have a popup that tells me it could be a resource part of storage cluster which it is not.
• Uninventory of platform always display a message You are going to uninventory at least one resource that may be used by the storage cluster when its not.

Resolution

JON Storage nodes are managed and monitored with the Storage node plugin. That is why each Storage Node box needs to have an agent installed.The message you saw is a guard to remind you about that. So if you want to decommission the agent, you'll have to decommission the storage node first.Once you have re-imported your agent, you'll be able to re-deploy a storage node.

A JBoss ON storage node is required for a JBoss ON system to function. Additionally, each host that will run a JBoss ON storage node must also have a JBoss ON agent installed.

If you remove the agent or the platform resource, you will essentially remove the storage node. This will leave your storage node in an unmanaged state. Additionally, if this is the only storage node deployed in your JBoss ON system, your JBoss ON system will fail to collect metrics once you remove it from the system.
