[ceph-users] ceph and raid 1 replication

Hi every one, I'm new to ceph and I'm still studying it. In my company we decided to test ceph for possible further implementations. Although I  undestood its capabilities I'm still doubtful about how to setup replication. Once implemented in production I can accept a little lacking of performance in favor of stability and night sleep, hence, if in testing area I can introduce ceph as network storage, I'd like to replicate some osds' drives as I'd do with raid 1 once in production. The goal would be hosting data for kubernetes storage classes. so questions are: 1) what do you think about this kind of solution 2) How can I setup full replication between osds? thanks in advance Rob
