[SOLVED] Ceph not working after upgrade to PVE 8.1

[s5labman]

Hello,

I've got a 4 node PVE cluster with 3 of those nodes sharing a ceph pool. I'm running Ceph Quincy 17.2.7. I did an upgrade from Proxmox 7.4 to 8.1 and followed the steps on the 7 to 8 guide including updating to the correct repos for both PVE and Ceph. While the PVE upgrade seems to have gone fine Ceph itself is now broken in this one node. I already unset the global noout from another note but now I can't even run any ceph commands from the 8.1 node as they all just hang. The overall Ceph status is unhealthy and shows 1/3 degradation on the cluster including the monitors, managers, and OSDs all showing up as down on that host. Could someone help me with how to fix this please?

I figured out my problem. I ran into the network error where the network interface changes names https://pve.proxmox.com/wiki/Upgrade_from_7_to_8#Network. Ceph was not able to bind to the IP because of that. I had to update the config file in the OS and bring up the interface again for it to work. Then restart monitor and manager services. Issue resolved.
