Description
Please, answer some short questions which should help us to understand your problem / question better?
- Which image of the operator are you using? registry.opensource.zalan.do/acid/postgres-operator:v1.9.2
- Where do you run it - cloud or metal? Kubernetes or OpenShift? [Bare Metal K8s]
- Are you running Postgres Operator in production? Yes
- Type of issue? [Question]
We run Single Node and Multi Node CLusters and recently moved storage to ZFS. On our Single Node Clusters, we have 2 mirrored zfs pools, each are mapped to a different openebs provider Storage Class.
We would like to be able to put the master on one storage class, and replicas on another, to keep the data physically separated, and let us use zfs to snapshot the replica only
Is this possible? So far I can not see a way to achieve this, but likely I'm missing something obvious
Many thanks in advance

Research direction
No repository files, tests, or entry points are mentioned. Start by locating the operator configuration for storage classes and master/replica placement, then determine whether separate classes can be assigned on a single node. Done means documenting or implementing a supported way to place the master and replicas on different ZFS-backed storage classes.
