HBA Passthrough Issues

[smash0573]

Hi there

New to Proxmox, but having a ton of issues with trying to pass through my LSI HBA (flashed to IT mode) into Truenas VM.

I'm on a Dell R630. I confirmed Iommu is enabled through reading several forums and changing . As soon as I turn on the Truenas VM, the rpool states an uncorrectable I/O failure, and the system becomes unresponsive. (Picture attached). I've been searching for weeks on how to properly configure this HBA, but I'm stuck at this point.

I confirmed /etc/modules has the following:

# Parameters can be specified after the module name.
vfio
vfio_iommu_type1
vfio_pci

lspci shows: 03:00.0 RAID bus controller: Broadcom / LSI MegaRAID SAS-3 3008 [Fury] (rev 02)

I'm not sure what other information I can provide. I just want to be able to use these disks in this NetApp4243 without causing IO errors, etc.

Any advice is appreciated!

Check your IOMMU groups. No other device except for bridges should use the same IOMMU group that your HBA is using: pvesh get /nodes/{nodename}/hardware/pci --pci-class-blacklist ""
Also check that your rpool disks are not connected to the same HBA.

No, I'm just an idiot. I noticed after running the pvesh that I was passing the dell perc controller through... not the LSI HBA.

Once I assigned the hba, I was able to get the VM to boot without crashing my entire system. Thanks for the help
