I’m running Proxmox 9 on a server with currently a single LXC running. On no apparent time schedule, within a day but frequently within an hour, the host will stop responding to SSH, pings and the web UI stops updating. However, the LXC continues to run happily. The only way to bring the host back up is to power cycle the server.
Has anyone got any troubleshooting tips?
Very niche case, but I saw pretty much the same thing.
I was running from an SD card on the iDSDM in a Dell server. The module was flaky and I’d have to power it all off and pop the SD card out and back in then bring it back up.
Unlikely to be the same thing, but maybe some breadcrumbs to start your search
Side note: do not install Proxmox on cheap storage mediums
I wonder if it is the same issue. I installed on an emmc module which isn’t recommended by Proxmox but I thought I’d get away with it. I might try reinstalling to another drive and see if it still happens.
Huh. Maybe it is related then. For what it’s worth I ended up moving to a real drive, still solid state, a while ago and it’s been working fine ever since.
Hardware issues are often the case. I’ll put my advice as a top comment.
Good point. All my VMs were on a zfs array.
It seemed like enough of the system was in ram that it could still run, but anything that needed the root file system was out of luck.
