Hi All, I want to understand on how do CEPH users go about Quota Management when CEPH is used with Openstack. 1. Is it recommended to use a common pool say ?volumes? for creating volumes which is shared by all tenants ? In this case a common keyring ceph.common.keyring will be shared across all the tenants/common volume pool. 2. Or is it recommended to use a pool for each tenant say ?volume1 pool for tenant1? , ?volume2 pool for tenant2" ? In this case we will have a keyring per volume pool/ tenant I.e. Keyring 1 for volume/tenant1 and so on. Considering both of these cases how do we guarantee that we enforce a quota for each user inside a tenant say a quota of say 5 volumes to be created by each user.
