PSMDB Cannot backup cluster: "Waiting for backup metadata"

Hi! I have a running installation of PSMDB. I created a manual backup with the following command:

cat <<EOF | kubectl apply -f-
apiVersion: psmdb.percona.com/v1
kind: PerconaServerMongoDBBackup
metadata:
  name: initial-backup
  namespace: psmdb-db-4-0
spec:
  psmdbCluster: psmdb-db
  storageName: mys3
EOF

But there is no backup pod, and the operator says:

{"level":"info","ts":1637862098.8842378,"logger":"controller_perconaservermongodbbackup","msg":"Waiting for backup metadata","PBM name":"2021-11-25T17:41:23Z","backup":"initial-backup"}

Here, the result of kubectl describe perconaservermongodbbackups.psmdb.percona.com -n psmdb-db-4-0 initial-backup:

Did I miss something?

Hello @Antoine ,

the backup pod is not going to be created, as backup is handled by the backup container which runs within the replicaset pod.

Could you please check the logs of this container?
Anything in the kubectl describe psmdb-backup initial-backup ?

Hello @spronin,

Thanks! I’m used to see a pod and not a sidecar container to do backups, sorry. The backup is OK now (the logs of the backup container helped me to find a permission problem). We can close this, thank you!
