2 hosts off the cluster

[Curt Hall]

I configured a new host (eastproxmox1) on main office network/IP then once my switch was ready, moved it to new office location with different IP.
Changed the IP (etc/pve/corosync.conf) but it doesn't show in the cluster, its old IP only shows when logged into proxmox1.

Since it didn't work, we started to change the other hosts' corosync file starting with proxmox6 and now its not in the cluster.
I SFTP'd into the files of proxmox6 and the entire etc folder was empty. (no idea what happened, not sure if physical box is bad or not at this point)

How do I get eastproxmox1 to show correct IP on cluster again and get proxmox6 back into cluster due to missing files?

host list:

NORTH OFFICE:
proxmox1
proxmox2
proxmox3
proxmox6 (8 VM's to rescue)

EAST OFFICE:
eastproxmox1 (60 VM's but all new and never used yet since its new deployment)

There is a significant number of threads on this topic in the forum. Most of the discussions/procedures start with a cluster in a good state. Unfortunately yours is not..
Here is the first google hit for "proxmox cluster ip change": https://forum.proxmox.com/threads/change-cluster-nodes-ip-addresses.33406/ .
This thread contains a wealth of helpful information, commands to run, outputs to check, etc.

You have few options, which way you go depends on the urgency of your situation:
Have time: try to fix the cluster from current state using information from the documentation/wiki/threads
Need fix soon: try to unwind your changes to get to good state and start from the beginning
Urgent: buy subscription, open a case and work with PVE support

Good luck

on eastproxmox1 the /etc/pve/corosync.conf file is wrong but i can't edit, permission denied.

It states to stop corosync service to edit, but stopping the service does NOT allow edits still, weird.

 

[bbgeek17]

Before stopping corosync I would have run "pvecm status" to understand what status my cluster is in. Likely its in RO mode due to loss of quorum. The earlier section on that page may be more useful to you.
I hope you are keeping track of all the changes you are making.

Good luck
