[ceph-users] Public access to RBD

I would like to allow users to create,use and delete RBD volumes, up to X GB, from a single pool. The user is a Debian GNU/Linux box using krbd. The sysadmin of the box is not trusted to have unlimited access to the Ceph cluster but (s)he is not malicious either. Permissions and quota are safeguards to prevent mistake.

While it seems possible to grant access to a single pool to a given cephx client with

   ceph-authtool -n client.foo --cap osd 'allow rwx pool=customer-pool

and the cap parser suggests even more flexibility


the documentation states that it should not be done


Suggestions about how to approach this use case are most welcome :-)
