    VM Migration: Unable to set the IP of the target node.

    I've spent so many hours and pulled too many hairs for this already. TLDR: Migrating a VM fails because ssh of the target node listens on IPv6 only (as desired+configured), and migration is attempting connection to IPv4. All I want is the connection to go through IPv6, or the VPN IP. The...

    Replace all SSDs on a 3 nodes cluster

    Hi everyone, I have a 3 nodes cluster running on PVE 6.4 with a total of 24 SSDs with CEPH. Considering that: - the cluster can be brought to a total stop - each node is more than capable to host all the machines - new SSDs are bigger (from 960GB to 1.92TB) - I'd highly prefer to not stress the...
