SOLVED HBA stuck with kernal VFIO driver

[platinumjsi]

So I removed a GPU from my system that I had passed through to a VM today and on reboot the system could not detect my drives.
A friend has run me through a few things and it appears the HBA is using the Kernal VFIO driver.
I tried putting the GPU back in and everything works again.
The GPU is not however seen now under GPU isolation so I cant seem to fully remove it now.
Any idea how I can fully remove the passthrough which seems to be stuck somewhere and get the system to boot and function without the GPU?

Thanks

Hey @platinumjsi

Can you provide the output of cat /proc/cmdline here?

Cheers, fixed it now.
For anyone coming from Google in the future:
I had to plug in a different GPU to the one I was originally using, this one showed up in GPU isolation, I enabled it and rebooted, I then removed it from GPU isolation and rebooted again, I then powered down the machine pulled the GPU and all is good.

Thank you very much. This worked for me too. It is turn-it-off-and-turn-it-back-on-again.

Note to self: make sure the GPU is un-isolated before removing it.

I've noticed that a lot of reboots seem to make things work when changing networking settings, but didn't think of it for this problem until I saw your post.
