[Zyxel NAS326] Debian MVEBU - missing one HDD

I just got Debian running on my NAS326. I'm using the rootfs 5.2.9 with kernel 5.5.3 (both from here).

Everything seems to work fine, with one exception. I seem to be missing a hard drive. I have two identical drives installed in the bays, and the stock firmware shows both of them. Both in the GUI and on the command prompt (/dev/sda and /dev/sdb).

However, the Debian system only shows one disk as /dev/sda, my flash drive as /dev/sdc, and a bunch of NAND stuff. But there is no /dev/sdb, and the HDD seems to be invisible.

I've tried zeroing both HDDs completely in my PC (in case some weird non-standard RAID stuff from the original firmware was causing issues) but it doesn't change the result.

Looking at the output of dmesg (see attachment), it seems to detect both drives initially. But then it just prints: "ata_id[3338]: unable to open '/dev/sdb'". And I can't figure out why. Since the stock OS finds both drives, I assume it can't be a bad connection or drive defect. But what could it be?

NeedMoreCoffee,

I might have missed a patch for this box. Let me check and come back.

NeedMoreCoffee,

Duh :) I've missed the patch for this box. Here attached is the new DTB: armada-380-zyxel-nas326.dtb

Download the new DTB to /tmp and replace the current DTB with it.

cd /boot/dts
cp -a armada-380-zyxel-nas326.dtb armada-380-zyxel-nas326.dtb.orig
cp -a /tmp/armada-380-zyxel-nas326.dtb .
sync

And then reboot. Please report back here if you see 2 HDDs again.

Hello bodhi!

Yes, that seems to fix it. Of course, I also had to rebuild the uImage according to the instructions, since the DTB file is baked into that. But after that, I now have my two drives:

# inxi -D
Drives:
  Local Storage: total: 3.65 TiB used: 1.30 GiB (0.0%) 
  ID-1: /dev/sda vendor: Seagate model: ST2000VX000-1ES164 size: 1.82 TiB 
  ID-2: /dev/sdb vendor: Seagate model: ST2000VX000-1ES164 size: 1.82 TiB 
  ID-3: /dev/sdc type: USB vendor: SanDisk model: Ultra Fit size: 14.32 GiB

Thanks for your help, and your work on this project in general!

Cool! I forgot that we have started using appended DTB for this box, too :)
