Bug Summary

Is there any documentation that explain how to override the numberOfReplicas for the Longhorn storageclasses ? In the documentation, there is only : postgres_storage_class option

spec:
  accessModes:
    - ReadWriteOnce
  capacity:
    storage: 8Gi
  claimRef:
    apiVersion: v1
    kind: PersistentVolumeClaim
    name: postgres-13-awx-demo-postgres-13-0

Hey, Correct me if I'm mistaken, but as far as I know, it isn't possible to define the number of Longhorn replicas in the PVC, only in the StorageClass. Therefore, it's not possible to create an option to override the replica count.

Instead, you should create an additional StorageClass for Longhorn that has a different replica count, and reference it to the AWX resouce.

Yes, that is the right way to do this.

You might also want to check which ReclaimPolicy you use, i.e. 'Retain' instead of 'Delete' to not lose data if the PVC gets delete for $REASONS...
