            Determine the affected pool with 'ceph df detail', for example looking
            at QUOTA BYTES and STORED. Either increase the pools quota, or add
            capacity to the cluster first then increase it's quota
            (e.g. ceph osd pool set quota <pool_name> max_bytes <bytes>)
