If you're not using CephFS, you don't need metadata or data pools. You can delete them. If you're not using RBD, you don't need the rbd pool. If you are using CephFS, and you do delete and recreate the metadata/data pools, you'll need to tell CephFS. I think the command is ceph mds add_data_pool <new_data_pool_id>. I'm not using CephFS, so I can't test that. I'm don't see any commands to set the metadata pool for CephFS, but it seems strange that you have to tell it about the data pool, but not the metadata pool.

In order to decrease those settings, you'll need to delete and recreate the pools.
