nf ceph mon

The nf ceph mon command creates a Ceph Monitor on a specific node and disk.

Monitors maintain the cluster map — a critical data structure that all Ceph daemons use to discover each other and understand the cluster topology. You should deploy an odd number of monitors (3 or 5) to maintain quorum. Monitors are the first daemons you deploy when setting up a new cluster.


Usage

Terminal
$ nf ceph mon --node <node-id> --disk <disk-id>
