"crm resource cleanup" is the command you're looking for, probably. It's
not unmanaged due to the meta-attribute, but due to an error the cluster
couldn't recover from.

Perhaps it'd make sense if crm_mon distinguished these two modes better
and printed "FAULTY" instead.

(It probably also indicates you don't have fencing configured correctly,
which is the normal way how pacemaker would recover from a resource that
failed to stop, which is the most common path leading to this state.)
