Overview

I've updated PGO to 5.8.0, now all my Repo-Hosts are upgrading and are not able to come up because of the pgbackrest-log-dir Init-Container.

chmod: changing permissions of '/pgbackrest/repo1/log': Operation not permitted

I've viewed the command and noticed 0775 permissions are trying to apply on /pgbackrest/repo1/log
Now I have created a new CIFS Volume with the exact permissions set to 0775, but still the same problem.

Environment

Please provide the following details:

  • Platform: Kubernetes RKE2
  • Platform Version: v1.32.3
  • PGO Image Tag: ubi9-5.8.0-0
  • Postgres Version: 17.4
  • Storage: vsphere-csi for data, and SMB / CIFS for Backups

Steps to Reproduce

REPRO

  1. install PGO 5.8.0
  2. create a CIFS/SMB StorageClass
  3. apply
apiVersion: postgres-operator.crunchydata.com/v1beta1
kind: PostgresCluster
metadata:
  name: test
  namespace: default
spec:
  backups:
    pgbackrest:
      global:
        repo1-retention-archive: '1'
        repo1-retention-diff: '1'
        repo1-retention-full: '1'
        repo1-type: cifs
      repos:
        - name: repo1
          schedules:
            full: 0 1 * * *
          volume:
            volumeClaimSpec:
              accessModes:
                - ReadWriteOnce
              resources:
                requests:
                  storage: 10Gi
              storageClassName: smb
  instances:
    - dataVolumeClaimSpec:
        accessModes:
          - ReadWriteOnce
        resources:
          requests:
            storage: 5Gi
      name: ''
      replicas: 1
  port: 5432
  postgresVersion: 17
  users:
    - databases:
        - test
      name: test
  1. database and repo host are not getting ready

EXPECTED

  1. it should work like bevore (PGO 5.7.4)

ACTUAL

  1. container pgbackrest-log-dir: chmod: changing permissions of '/pgbackrest/repo1/log': Operation not permitted

The Bug is still present in 5.8.1!

Hi @MSandro, that is correct. We're actively working on a fix for this, but unfortunately it didn't make it into the v5.8.1 release.

We therefore plan to have a fix ready for the next release in May. And in the meantime, I'll note that the v5.7.5 release, which also just came out last week, does not have this issue.

Thanks for you patience with this one, and if you have any questions, please feel free to reach out.
