Greetings, I come here after many days of bashing my head into a wall with one of my new Proxmox 6 nodes. I am just a home user, so please go easy on my less-than-conventional setup when I explain it.
I have 3 Proxmox 6 nodes, each one running GlusterFS as well, for shared storage to be able to migrate VMs around. This all works great, even connected with just one interface for all of these nodes. Like I said, I am a home user, and only want to run a few VMs on this, so I am not all that worried about performance.
There is one wonky issue I am struggling with. Sometimes, be it once every few days, or 3 times in an hour, the second node in the group goes out to lunch as far as corosync is concerned. It still responds on the network, but corosync isn't able to communicate with the other two nodes, anymore. When that happens, I am not sure if it is the second node doing it, but node 1 and node 3 *both* reboot almost immediately, I assume as some form of protection for the cluster. It takes all the VMs with it. Sometimes corosync is still out to lunch when the other two nodes come back, and they refuse to start the VMs until I reboot the second node. I should also mention, that pve2 (the second node) never hosts any VMs, it's just there for quorum purposes, as it's older hardware with no hardware VM extensions, and it is able to support the glusterfs shared storage perfectly fine.
Here is a syslog snippet from when this all goes south on pve2:

Aug 7 09:28:13 pve2 pvestatd[1327]: got timeout
I have no idea what else to even check here, and like I said, the network is working perfectly fine, which is why I assume the reboots are happening.
One last tidbit, hopefully it leads to something. this problematic node wasn't installed like the rest (using the proxmox install ISO), because I couldn't get it to agree with the onboard GPU for that hardware. Instead, I had to do a fresh Debian Buster install, and then layer Proxmox over the top of that.
I found a forum post with someone explaining a similar issue, which can be found here, and I tried the solution suggested, which didn't help.
I have 3 Proxmox 6 nodes, each one running GlusterFS as well, for shared storage to be able to migrate VMs around. This all works great, even connected with just one interface for all of these nodes. Like I said, I am a home user, and only want to run a few VMs on this, so I am not all that worried about performance.

Aug 7 09:28:13 pve2 pvestatd[1327]: got timeout
I have no idea what else to even check here, and like I said, the network is working perfectly fine, which is why I assume the reboots are happening.
One last tidbit, hopefully it leads to something. this problematic node wasn't installed like the rest (using the proxmox install ISO), because I couldn't get it to agree with the onboard GPU for that hardware. Instead, I had to do a fresh Debian Buster install, and then layer Proxmox over the top of that.
I found a forum post with someone explaining a similar issue, which can be found here, and I tried the solution suggested, which didn't help.
