Die PVC wird erzeugt, bleibt aber auf 'Pending' weil 'No Persistent Volume'

Wenn man die storage class auf "thin-csi" festlegen will:

kommt:

mb@nbo00370518:~/dave2/helm-charts/charts/dave$ helm upgrade --install -f values.yaml -f values-lhm.yaml dave .
Error: UPGRADE FAILED: cannot patch "dave-postgresql" with kind StatefulSet: StatefulSet.apps "dave-postgresql" is invalid: spec: Forbidden: updates to statefulset spec for fields other than 'replicas', 'ordinals', 'template', 'updateStrategy', 'persistentVolumeClaimRetentionPolicy' and 'minReadySeconds' are forbidden

@klml kannst du da helfen?

gislab-augsburg commented 4 months ago

Wenn ich per Hand eine PVC erstelle mit Namen 'data-dave-postgresql-0' wird die vom postgresql pod genommen und er fährt hoch.

klml commented 4 months ago

mit "no storage class is set" kam schon öfters vor. Hattest du postgresql.storageClass intern gesetzt?

gislab-augsburg commented 3 months ago

ich hab in den values-lhm gesetzt:

postgresql:
  storageClass: "thin-csi"

-> kein Effekt

postgresql:  
  primary:
    persistence:
      storageClass: "thin-csi"

->

mb@nbo00370518:~/dave2/helm-charts/charts/dave$ helm upgrade --install -f values.yaml -f values-lhm.yaml dave .
Error: UPGRADE FAILED: cannot patch "dave-postgresql" with kind StatefulSet: StatefulSet.apps "dave-postgresql" is invalid: spec: Forbidden: updates to statefulset spec for fields other than 'replicas', 'ordinals', 'template', 'updateStrategy', 'persistentVolumeClaimRetentionPolicy' and 'minReadySeconds' are forbidden

Forbidden: updates to statefulset spec

@gislab-augsburg da musst du das statefulset vorher einmal deleten

:man_facepalming: ok so geht es:
