Hi all,
Still very new at this so please bear with me.

I have 2 node cluster that I set up and had working earlier this week. I upgraded my router and that caused a whole bunch of IP issues of both nodes. I updated them and in all the correct place: /etc/network/interfaces, /etc/hosts, and /etc/pve/corosync.conf. however the nodes refuse to communicate with each other and quarum has locked me out from removing or adding another node.

Attaching the output of journalctl -b -u corosync if that help.

Code:
May 01 18:33:45 BlueBox systemd[1]: Starting corosync.service - Corosync Cluster Engine...
May 01 18:33:45 BlueBox (corosync)[1285]: corosync.service: Referenced but unset environment variable evaluates to >
May 01 18:33:45 BlueBox corosync[1285]: parser error: /etc/corosync/corosync.conf:27: Value of key "totem.config_ve>
May 01 18:33:45 BlueBox systemd[1]: corosync.service: Main process exited, code=exited, status=8/n/a
May 01 18:33:45 BlueBox systemd[1]: corosync.service: Failed with result 'exit-code'.
May 01 18:33:45 BlueBox systemd[1]: Failed to start corosync.service - Corosync Cluster Engine.



Thank you for any help.
