ceph: vm with one copy only?

[benoitc]

I was reading the redhat papr about deploying mysql on ceph:
https://www.redhat.com/en/resources/mysql-databases-ceph-storage-reference-architecture

When MySQL replication is used in conjunction with Ceph RBD volumes instead, only the leader would have a full copy of the dataset, and the followers would operate on a thin-provisioned clone of the leader’s dataset. Furthermore, while the leader’s dataset would be fully replicated to all storage nodes, the follower clones would have only one copy

How can we do the same with proxmox. Is there a way to create a vm with only one copy? should I create a specific pool for it?
