creating a static PVC from an existing CephFS volume

[duffrecords]

Now that the cephfs volume type has been removed in Kubernetes 1.31, I'm trying to understand what the appropriate replacement would be. I have an existing CephFS file system that I would like to attach to containers so they have access to some shared files. I read the instructions for creating a static PV and PVC from an existing subvolume but I don't have any of those--just a single CephFS volume. Is it possible to do this without creating a subvolume? The documentation seems to be focused on how to provision volumes of a fixed size but, as I understand it, CephFS scales with the underlying object store. Would this mean I'd need to specify the size of the entire CephFS system? I want to make sure that creating a static PVC is not going to try to provision a new block within the FS or delete existing data.

Yes it should be possible

Static PV doesn't create anything on the ceph system, it supports only mounting/umounting the PVC
