How to delete "CephFS"?

[encore]

Hi,

I am currently playing around with CEPH. Configured it via proxmox gui, added some osds, added a Metadata Server and finally created "CephFS" in the "CephFS" tab:
http://prntscr.com/nuzcyd

Unter "Storages" (proxmox cluster) I accidently deleted the CephFS storage. When I try to create it again, it stays "inactive".
So I would like to delete "CephFS" and create it again. But there is no destroy button (see screenshot above).

Also those pools can't be deleted:

pveceph pool destroy cephfs_data
storage does not support content type 'none'
mon_command failed - pool 'cephfs_data' is in use by CephFS

Any ideas?

ceph fs rm cephfs --yes-i-really-mean-it
+ removing the two pools via GUI helped

This only removes the storage and does not remove the underlying CephFS. When you re-create the storage entry, check if the keyring exists.

for destroying the underlying cephFS (and all it's data!) see: https://pve.proxmox.com/pve-docs/chapter-pveceph.html#_destroy_cephfs

confirmed, not working, the cephfs remains

Ensure you actually followed the steps, and post any errors and other details that you see.

Hi there,

It's working as intended; just did here in my cluster. You must confirm that no VM/container is accessing the CephFS, that you unmounted in every node and that you stopped all standby MDS and the MDS that is running the CephFS that you want to remove.

Best regards.

Worked for me, too. The only thing that wasn't clear from the docs is how to disable the storage entries: it can be done in `Datacenter > Storage`

Yes, I did it there, to ensure that no VM was accessing it, then proceeded with the steps in the docs (did it twice yesterday, PVE 7.4).

Best regards.
