If I just add a PVE CephFS with an arbitrary name through webUI I get error 
> create storage failed: error with cfs lock 'file-storage_cfg': mount error

If I then try the same again:
> create storage failed: error with cfs lock 'file-storage_cfg': ceph authx keyring file for storage 'sdf' already exists! 

but no configuration entry is there, so I cannot clean this up easily and a
user probably does not know that he has to delete:
/etc/pve/priv/ceph/sdf.keyring

Such an error should be idempotent?
