Spies Posted April 19, 2017 Share Posted April 19, 2017 I've been having a problem for some weeks where my entire server would reboot but I have been unable to capture any kernel panics, although I have 'Fix Common Problems' running in Diagnostics mode (always writing log to the flash drive) it stops writing to it some hours before the system crashes/resets. I have a basic license and I'm using 6 drives (but the same issue was occurring before I added the 6th), I was passing through a 1TB USB drive to my Windows Server 2016 VM for backups to be written to, however because of the issues I've been having with the server crashing, I have removed it as it was preventing the array from starting automatically (too many devices for my license). Since the drive has been disconnected, the server hasn't restarted itself once, it now has over 4 days uptime which I don't think I've seen on this particular hardware configuration. Has anyone else had similar issues with passing through USB devices like this? Is there anything I can try to see if I can make a difference as I would like to use Windows Backup to save images to the USB HDD? Would passing through the USB controller help at all (using vfio-pci) or can I pass-through a single port? Obviously unRaid will still need access to the flash drive so I can't pass everything through, the relevant section of my IOMMU looks like this: Suggestions please!

Paul_Ber Posted May 28, 2017 Share Posted May 28, 2017 I had my unRAID system crash a week ago when I was using an USB port to charge a phone. It also happened to be ports that I passed the whole USB controller. The system was unresponsive and couldn't even ssh in. Link to comment
