When setting up Zabbix monitoring for the home lab, we determined that the Ceph storage network was not initially configured as per best practices.
Rather than configuring Ceph with the monitors communicating on a “public” network and using a private “Cluster” network for osd communications, we had put all Ceph-related communications on an isolated V-lan. This functioned quite well, however was not in line with best practices, and left no way for us to use Ceph’s built-in Zabbix reporter.
After a large amount of research, we determined that the most often given advice regarding modifying the storage network configuration of an operational Ceph cluster is “Don’t.”
Taking this to heart, we started the backup process.
