[SOLVED] [HELP] Blew up corosync

[bferrell]

Hello, I really need some help. I have a 4 node cluster, and I was trying to add redudant ring addresses to the cluster and blew it up. I tried to follow this guide, I did copy and backup the configuraiton. I made a mistake, and now when I try to edit the Corosync file I get a permissions error which is totally freaking me out, and I'm afraid to do much in fear of making it much worse.

If you look at the current coro file below you can see in node 2 I screwed up and left 3 ring0 entries. How can I fix this (when I can't even write the file)????

UPDATE: I was able to stop the cluster service, force it into local mode, and make the edits in the /etc/corosync directory, reboot, and get the cluser back up by using this article, so I think I'm back up. https://pve.proxmox.com/pve-docs/chapter-pvecm.html#pvecm_separate_node_without_reinstall


systemctl stop pve-cluster

systemctl stop corosync

pmxcfs -l
