apalrds adventures | Renumbering my PROXMOX Cluster because of an IP Oops! @apalrdsadventures | Uploaded April 2023 | Updated October 2024, 9 hours ago.
Sometimes you need to change the IP addresses on your Proxmox cluster, and it's never a particularly fun time. But, come along for the tale of my late-night frustration as I realized I'd have to renumber my cluster, and learn from my mistakes so you don't make them too.
In this case it was caused by Comcast changing my IPv6 prefix (something they haven't done in 2 years), but it can happen any time you need to move IP ranges for any reason. So, make sure you have backup ring networks for Corosync, and be aware of how to bring the cluster back from any accidents.
