VM with GPU passthrough not starting after drive rebuild and ssh/file server issues

Featured Replies

Hey hopefully someone can help! 


Background: I accidentally hit a drive carrier and popped a drive out of the array while working on another server.  After pushing it back in my drive array was showing the drive as disabled so I stopped the array > detached the drive > restarted array > stopped array > then attached the drive to the array and restarted to do a rebuild. Once completed, I am experiencing the following issues:

 

1. I only have one vm and was passing through an Nvidia M2000 gpu that WAS WORKING great until after the rebuild. I read up on so many forum topics attempting to get this working again and most are the same issues dealing with iommu groups and syslinux config. That is not my issue. When starting the vm I don't get any error messages, however, the os (debian) fails to load. Using vnc instead of gpu works fine. I also tested creating another vm from a template using gpu passthrough with the M2000 and it works without issue

 

2. Unstable ssh sessions. Prior to the rebuild I had zero issues with ssh sessions. After the rebuild I continuously get dropped sporadically. Also, during the session I experience 2-3 sec of lag occasionally while typing. Of note, if I use the built-in terminal session on the webui I have zero issues.

 

3. Servers connecting to file shares over nfs are constantly having issues now that worked flawlessly before. Constantly seeing "nfs: server 10.0.3.2 not responding, still trying" and very slow response when changing or listing mounted directories.

 

I've attached an export of my logs. Thank!

Did you ever try passing your m2000 to a Windows VM?
