Hi there,

 

I have 3 x 4TB drives and a crucial SSD in the 4 slots of my QNAP.

 

In the Bios

•   All disks can be seen
•   SATA Mode selection is set to AHCI
•   Boot order is UEFI : Sandisk

 

When the system boots only 2 of the 4TB disks can be seen.

 

Any advice please?

 

Thanks

It uses a Marvell controller, they are not recommended for Unraid, you can try this to see if it helps:

Do I put

iommu=pt

in /boot/EFI/boot/syslinux.cfg ?

Ignore that, I found out where to put it.

Unfortunately this did not work. Shame because I was looking forward to given this a try.

Not really surprised since that usually helps when none of the disks are detected, Marvell and Linux just don't go together.

This is true, other distributions are having the same issue. I'm stuck with QTS that will never update 😒

So...I have not given up with this project yet.

I am back running QTS 4.2.8, is there a way I could use the Qnap kernel with the Unraid distro? Or would that be frowned upon?
