WD – HGST – STEC 1TB MLC PCIe Solid State Accelerator S1122X1000M4

Hi,

 

Just bought a PCIe accelerator card as described above (link) and i can't use the drive.

 

I may be over my head on this one BUT as far as i know, the driver was included per customer req in unRAID 6.6.0

added per customer request:

CONFIG_BLK_DEV_SKD: STEC S1120 Block Driver

 

The card shows up in system devices as follows:

Quote

IOMMU group 28:[1b39:0001] 06:00.0 Mass storage controller: sTec, Inc. S1120 PCIe Accelerator SSD (rev 04)

But i can't find it as a drive in the WebGUI using unassigned drives or as a choice when i assign drives to the array.

 

From syslog:

Sep 23 19:16:17 Threadkiller kernel: skd 0000:06:00.0: STEC s1120 ONLINE

 

Any ideas? Do i have to compile drivers manually?

Update:

 

By adding "vfio-pci.ids=1b39:0001" to the Syslinux Configuration as below i managed to get the drive visible for passthrough when I edit a VM

 

 

But still no soup as I want to use the PCIe card as a unassigned device and run my VMs and dockers on it

I have one of these as well, hopefully someone knows how to get it working. I’d love to be able to use mine as a cache drive.

Sorry I found this so late!
This was my request to get the driver added and I was able to add this by creating this script and using User Scripts to load "At Startup of Array".
#!/bin/bash
echo "Creating drive directory in /mnt/disks"
mkdir /mnt/disks/skddrive   #This is the mount I chose since i exported my "disks" share
echo "Done!"
echo "Mounting drive to skddrive"
mount /dev/skd0p1 /mnt/disks/skddrive   #I partitioned the drive first, this references the device and first partition
echo "Done!"

Was solid until I upgraded from 6.9.2 to 6.10-rc2 where Limetech seems to have forgotten or removed this driver for some reason....

I just pulled it out and replaced with a SATA SSD to work around this for now.

I ended up using mine in a proxmox server. It worked fine until I upgraded to proxmox 7.1. According to this https://cateee.net/lkddb/web-lkddb/BLK_DEV_SKD.html it seems like the driver was removed from the linux kernel. Unraid 6.10 rc2 uses linux kernel 5.14.15, the driver was in 5.0-5.11.
