Additional Information

No response

[kosmoz]

Caused by persistentVolumeClaimRetentionPolicy (1.27 beta feature). We will remove this from the stateful set.

[kosmoz]

Note: to actually fix this issue, the StatefulSet must be deleted and recreated because persistentVolumeClaimRetentionPolicy is still in the managed fields.
