If you set up multiple monitors, which is best practice, you need a quorum to be established between your monitors for your cluster to operate.
A single monitor that cannot reach his peers simply don't know if they are down or if it is isolated from them.
Similarly, a leader exists only in a quorum.

Hello,I'm testing ceph with minimal config on our servers (I'm using ceph-deploy tool). We have 3 monitor nodes with 6 OSD. The worst scenario when only 1 monitor and 2 osd up. Unfortunatelly in this case I got just error when I run for example ceph -s, I think it couldn't reach the cluster (I turned down the leader monitor). How can I config ceph to work with only 1 monitor? It is possible? I read this page but this isn't clear exactly.
Thanks for your help!Sandor Szombat
