Hey everybody. Kinda new to Proxmox as I have been running it for a couple months in a 2 node HA cluster. I noticed there was a package update this morning for I think it was a kernel-helper package and after doing the update node 2 said I needed to reboot to take effect. I rebooted node 2 and now it's disconnected from my HA cluster. The node is back up, I can ping it, I can ssh into it, and I can actually access it through the shell menu in my node 1 proxmox GUI but the node shows with a red x on it in the GUI. How do I get the node back online in my HA cluster with node 1? Thanks in advance.

Try restarting the pve-cluster and corosync services on node 2 using the following command:
Bash:
systemctl restart pve-cluster corosync

If the issue persists, check the logs with journalctl -xe and verify the configuration in /etc/corosync/corosync.conf to identify any quorum or cluster issues.
 
check the logs of the system, in particular any errors logged by pve services during bootup..
 
Thank you for the help everybody. I tried restarting the corosync like suggested but it kept spitting errors out. I had been wanting to rebuild my hosts and cluster anyway so since I had backups of everything I just went ahead and rebuilt both nodes and my cluster and I am back up and running. Thanks again.
