Once you have a running cluster, you may use the ceph tool to monitor your cluster. Monitoring a cluster typically involves checking OSD status, monitor status, placement group status and metadata server status.

For high availability, a Ceph storage cluster relies on an odd number of monitors that’s more than one, for example, 3 or 5, to form a quorum. For this initial POC, I find 3 monitors to be fine,as it will grant HA solution and it will serve POC purpose.Later I am going to add more monitors. Monitor nodes are tasked with monitoring the system and act as the central management for the Ceph cluster. These servers can also be operated virtually, though, the use of one to three physical monitor nodes is recommended. OSD nodes provide the actual data storage for the objects and can be scaled according to the desired redundancy level.

The Ceph monitors must agree on each update to the monitor map, such as adding or removing a Ceph monitor, to ensure that each monitor in the quorum has the same version of the monitor map. Updates to the monitor map are incremental so that Ceph monitors have the latest agreed upon version, and a set of previous versions.
The main script is in the top right corner. Essentially we traverse the servers (nodes) and ceph osd instances throughout the cluster, collecting files (with find) that match the wildcard and are bigger than a byte.

You can run a cluster with 1 monitor but we recommend at least 3 for a production cluster. Ceph monitors use a variation of the Paxos algorithm to establish consensus about maps and other critical information across the cluster. Due to the nature of Paxos, Ceph requires a majority of monitors to be active to establish a quorum (thus establishing consensus).

Ceph went into recovery mode to keep my precious zeroes intact, and IO basically ground to a halt as the cluster recovered at a blazing 1.3MiB/s. I couldn’t hit the node with SSH, so I power-cycled it. It came back up, Ceph realized that the OSD was back and cut short the re-balancing of the cluster.
