Is there support for force deleting persistent volumes?

[Azuka]

I'm experiencing #32 on only one pod (a similar one works), so I tried to delete the persistent volume claim, then force delete the persistent volume itself (a manual delete didn't work and it's been stuck Terminating for more than an hour).

From the logs I see:

which stays in place even when I detach the volume and delete manually. Is there any way to "purge" a persistent volume? Thanks!

You can do a kubectl edit resource and then remove any finalizers. It's probably stuck at that level.

Thanks, that worked!

This works great. It clears out the PV but how can we prevent this from happening in the future? This seems a bit hacky.

I ran into same issue and tried to force delete PVC and PV as both were stuck into Terminating state for a while. I don't have feature-gate PVCprotection enabled still "Finalizers: [kubernetes.io/pvc-protection]" got added to PVC/PV config. Is that a bug ?
