Hi,

The equivalent in pacemaker is "managed" and "unmanaged" resources.

The usage depends on what tools you are using. For pcs, it's "pcs
resource unmanage <resource_name>" to freeze, and "manage" to unfreeze.
At a lower level, it's setting the is-managed meta-attribute of the
resource.

It's also possible to set the maintenance-mode cluster property to
"freeze" all resources.
