  2. Ceph down if one node is down

    Thank you Jarek for your time and your reply. I really need to read a manual on Ceph. I changed the setting: In 2 hours I think the redundancy will be over, then I will try a new test. I was desperate, even I thought to rollback to version 4.. Thanks again. Luca
