Does it make sense to have an option to clean PV before discovering it as a new PV?
Current lifecycle:
- raw disks -> mount points -> PV (available) -> PV (bound) -> PV (released)
^ |
| <---------- clean <-----------------|
New lifecycle (optional):
- raw disks -> mount points -> [clean] -> PV (available) -> PV (bound) -> PV (released)
^ |
| <---------- clean <-----------------|
use cases:
- if we clean the volume before provisioning it as a new PV into Kubernetes, it will be safe to delete the PV objects and don't worry about the data will be leaked. (https://github.com/kubernetes-sigs/sig-storage-local-static-provisioner/pull/126#issuecomment-511651492)
another case:
- I use cloud storage as local pv, after pvc&pod deleted, and cleanup pv successfully. But actually, cloud storage not works as expected. Then provisioner creates the pv with same name and path. Later another pod uses the pv, it finds some data not belong to itself.
so I think it really makes sense, at least, check or log if there are some data before pv available.
Yes I think this is a good idea, although this will cause the recycling flow to double for very large disks. We can add it as a new option
