I have been encountering strange networking behaviour and was hoping for help. Im, not a command line wizard and have hit a brick wall.
I have run Proxmox 7 on a 3-node cluster for the last year or so. 2x Optiplex 3080M's & 1x Optiplex 3070M.
I have never encountered any issues, but I recently upgraded from 7 to 8, where my network issues began. I was finding that after an hour or so of being online, pve3 would suddenly go offline (Optiplex 3070m). A hard restart would usually bring it back online, but an hour later, the same would happen again. It always seemed to be this single node.
I figured that perhaps I'd made a mess during the upgrade process, even though it seemed to go smoothly, so I decided to start fresh. I reflashed all 3 nodes with Proxmox 8 and clustered them without issues. I thought that was the end; however, I woke up this morning, and both pve2 & pve3 were offline. Once again, a hard restart fixed the connection issue but again, 5-6 hours later, nodes are going offline again.
I never encountered any issues before attempting the upgrade and have absolutely no idea what is causing this. Id prefer not to have to reflash them all back to 7 again if possible but I dont have the ability to troubleshoot this issue myself.
Any help or advice would be hugely appreciated. Thank you
