I switched the default storage class from "standard" to "standard-rwo", and I am facing several issues.
First issue was that helm would not update as the storage class changed. To fix this I manually deleted the pvc.
Now came the second problem. It's not possible to delete the pvc anymore as it gets stuck in "Terminating" for hours, currently 10 hours or so.
$ kubectl get pv | grep ...
pvc-22d389de-7847-4bbe-a7d7-29d68ac55c49 600Gi RWO Delete Terminating some-namespace/staging standard 21d
So how do I delete these pvcs?
$ kubectl describe pv/pvc-22d389de-7847-4bbe-a7d7-29d68ac55c49
