Hi Francois, I'm afraid that you need more rooms to have such availability. For data pool, you will need 5 rooms due to your 3+2 erasure profile and for metadata you will need 3 rooms due to your 3 replication rule. If you have only 2 rooms, there is possibility of corrupted data whenever you lost 1 of 2 rooms, erasure is distributing the chunk, not the copy. For metadata, the worst scenario is inactive PG if the room with 2 replicas is lost.
