TrueNAS/Proxmox Freeze

Hey everyone,

I’ve got a weird issue with my homelab/server and I’m hoping someone can point me in the right direction.

My setup:

  • Proxmox running for about 11 months
  • Around 13 LXC containers and 2 VMs
  • Updated about 2 months ago to Proxmox 9 / Debian 13
Everything worked flawlessly until recently. About 3 weeks ago I noticed that my TrueNAS VM randomly stops responding.

According to Proxmox, the VM still appears to be “running”, but:

  • I can’t see live stats (CPU/RAM usage just keeps loading)
  • It’s not reachable via IP
  • noVNC won’t connect
  • Trying to “Shutdown” or “Reboot” the VM from Proxmox doesn’t work — the VM just hangs. The only way to get it back is to force stop (STOP) and then start it again.
At first, I thought it was a one-time thing, but it happens repeatedly — sometimes after 1 hour, sometimes after 2 days, sometimes after 3 days. It’s completely random.

The NAS isn’t in daily use, so I didn’t notice right away. After the upgrade to Proxmox 9 I was also away for about 4 weeks, so I can’t say for sure if the issue started right after the update — but it never happened before.

All other LXC containers and VMs run perfectly fine.
I already tried:

  • Running a memtest → no issues found
  • Increasing RAM for the TrueNAS VM by +4 GB → no change
  • Updating/upgrading both Proxmox and TrueNAS → still happens
I’ve attached some screenshots of the configuration.
Before I start digging through logs — could someone tell me which specific logs would be most useful to share here (from both Proxmox and TrueNAS)?

EDIT:
1.Someone on Reddit told me to install the NIC E1000E Drivers, but i dont got a NIC E1000 interface!
2. The Third Picture is from now, The TRUENAS is not reachable anymore, RAM is nearly Maxed out. ( The last 9 month i only had 14GB ram to the Machine. I started upgrade it when it first crashed. Now it keeps filling up?


Thanks in advance for any hints or ideas!

Hi,

You can try to restart pveproxy and pvedaemon:
Code: 
systemctl restart pveproxy
Code: 
systemctl restart pvedaemon
Also, it makes sense to check the PVE host state if there no issues with free space etc.
 
How do you have your disks in TrueNAS connected to Proxmox? Are you passing through an HBA or some other kind of controller?

I hear you, but, that is not a reliable way to run TrueNAS. I have done it this way too in the past, but it does or can create issue for TruNAS because TrueNAS and by extension, zfs in TrueNAS doesn't own the devices. As a result, SMART doesn't work and a few other features don't work. Lots of people have had issues doing it this way. It could be a TrueNAS update that broke this, or it could be something upstream in Debian or it could be Proxmox that changed. Its hard to say. I changed my TrueNAS config when I added one of these to my system https://www.newegg.com/p/0ZF-010B-000B8. I pass through the entire controller and now TrueNAS can see and manage the disks down to the hardware level. If you have a M.2 slot you can spare, you might try one of these adapters. Mine has been working flawlessly for about a year now, through the Debian 13 upgrade as well as the Proxmox 9.0 upgrade and 2-3 TruyeNAS upgrades.
