Hello !
I use CAO 2.0.3 and create this minimal cluster
apiVersion: v1
kind: Secret
metadata:
name: cb-example-auth
type: Opaque
data:
username: QWRtaW5pc3RyYXRvcg== # Administrator
password: cGFzc3dvcmQ= # password
---
apiVersion: couchbase.com/v2
kind: CouchbaseBucket
metadata:
name: default
---
apiVersion: couchbase.com/v2
kind: CouchbaseCluster
metadata:
name: cb-example
spec:
image: couchbase/server:7.0.3
security:
adminSecret: cb-example-auth
buckets:
managed: true
volumeClaimTemplates:
- metadata:
name: couchbase
spec:
storageClassName: managed-premium
resources:
requests:
storage: 1Gi
servers:
- size: 3
name: all_services
services:
- data
- index
- query
- search
- eventing
- analytics
volumeMounts:
default: couchbase
I wanted to move this couchbase cluster in another kubernetes cluster and I set it up in hibernate mode by setting spec.hibernate=true. Then I took a copy of the pvc and restore them in another cluster.
When I restart the cluster by setting spec.hibernate=false I get this error message in the logs of the operator
persistentvolumeclaims \"cb-example-0001-default-00\" already exists

I probably missed something here, how the operator decide to recreate a new PVC or to reuse an existing one ?
