What do you mean ‘bring up the second monitor with enough information’? Here are the basic steps I took. It fails on step 4. If I skip step 4, I get a number out of range error. 1. ceph auth get mon. -o /tmp/auth 2. ceph mon getmap -o /tmp/map 3. sudo ceph-mon -i 1 --mkfs --monmap /tmp/map --keyring /tmp/auth 4. ceph mon add 1 <ip>[:<port>] 5. ceph-mon -i 1 --public-addr {ip:port} Thank you.

I’m trying to raise the cluster from 1 to 3 monitors. I think it breaks when I run ‘ceph mon add <mon-id> <ip>[:<port>]’ because it loses quorum before the new monitor is online. Thanks. Yep, that's exactly what's happening. If you bring up the second monitor with enough information to contact the first, they should sync up and form a quorum. Have you do e that? -Greg
