I am looking at the list of PVCs in GCP and I see
bitcoind-data-bitcoind-1andbitcoind-data-bitcoind-0. To confirm my understanding: we are running two replicas of bitcoind, each with its own PVC. Is this correct? If so, why don't we havebitcoind-data-bitcoind-0-pvc.yamlfile here as well?There was a problem hiding this comment.

bitcoind-data-bitcoind-0-pvcgot created automatically when we started the bitcoind statefulset withvolumeClaimTemplatesand just one replica.After the first replica synced we crated a snapshot of
bitcoind-data-bitcoind-0PVC and used it as adataSourceto create thebitcoind-data-bitcoind-1.
