OpenNebula Ceph monitor assumes all data in the Ceph cluster is available for ONE, i.e. max_avail. Monitor should check if there is a quota assigned to the pool and if so, use this value instead of max_avail. See #127 for a possible fix.

You can set LIMIT_MB, to limit maximum capacity allowed for the datastore. Could that address this issue?

It's more about monitoring than it's about not able to limit usage. A cloudadmin that is checking the datastores wants to see the amount of available storage, not some theoretical maximum. When datastore attributes "TOTAL_MB", "FREE_MB", "USED_MB" are used for monitoring a cluster, you also want to get the right values.
