But after removing the node from the cluster it will still have access to the shared storages! This must be resolved before you start removing the node from the cluster. A {pve} cluster cannot share the exact same -storage with another cluster, as storage locking doesn't work over cluster +storage with another cluster, as storage locking doesn't work over the cluster boundary.
