Description
when we use rbd mirror we must get class-write authority. But if we get this authority we can remove primary rbd image form remote cluster which is a potential risk.
I want to ask is there is any method to avoid this problem now.
my ceph version is : ceph 12.2.2

It's not possible since the remote rbd-mirror daemon needs to be able to (1) register with the journal and (2) create/delete snapshots for image syncing.
