I've been running Unraid for about 2 years without major issues but for the past 3 weeks, it has been crashing (completely shutting down) randomly. Sometimes it runs for a few hours to a couple of days (without issues) than crashes.
I run Unraid in a Proxmox VM for about 8 months in this rig (passing through a HBA with my 5 HDD and 1 SSD drives) and was working extremely reliably. About 3 weeks ago, I installed a GPU in my system (a RTX 3060) which coincided with the start of the Unraid VM crashes. I thought it could be a hardware issue, but my power supply has enough Wattage for the system with GPU (750W), I am not using the GPU in the Unraid VM (it's used in another Linux VM) and all other LXC/VM in Proxmox are running solid with Zero crashes. The system has been pulling 250W maximum and the crashes have been happening with the GPU in idle (with the whole computer pulling only ~90W).
When I initially installed the GPU, my motherboard (MSI Z790-P) changed the PCI IDs of the HBA and the onboard NIC. I updated the NIC ID in Proxmox and corrected the HBA ID for passthrough in the Unraid VM. With that, the Unraid VM was up and running and worked perfectly for a couple days when it started crashing.
What I did so far:
- I replaced the USB drive used for Unraid (mine was 3 years old) and put a new Kingston one (precaution measure).
- Increased the airflow in my case, as I read the HBA overheating could cause Unraid to crash (although it's the same HBA that worked well before)
- No hardware changes to Unraid (the HBA and a couple USB ports are the only hw passthrough I have in Unraid) - see VM config attached
- Updated all plugins and containers in Unraid to the latest version
- Enabled syslog server and syslog recording to the flash drive for diagnostics (attached)
- Disable the Tweaks and Tricks plugin as I saw errors related to it in the syslog (and it was a leftover plugin from when I used to run Unraid bare metal)
- Tried to run Unraid in Safe Mode (no plugins) - the system still crashes
If it was a hardware issue, why my other Proxmox (or the other LXC/VMs) are stable?
And the system runs perfectly until it randomly crashes. Is there anything I'm missing in the Diagnostics? What could be the culprit?
