Problem booting from HDD - Zyxel NAS326
August 08, 2017 09:27AM
Hello again ;)

unfortunately I could not manage to boot from internal Harddisk on my brand new NAS326. After a while it boots to stock firmware.

This is how partitions and fstab look like:
/mnt # parted /dev/sda print

Disk /dev/sda: 3001GB

How could I find out what the problem is without usb-serial?

usb-serial is not attached. I could not find any doc how to attach usb-serial. Does anybody know where on the NAS326 Board to connect it?
I still have the USB-to-Serial Cable which I use for NSA325. Is this compatible to NAS326?

Thanks in advance,
Peter

Hi Peter,

Welcome back :)

Running stock u-boot, we cannot see anything during booting without serial console. We can only guess the problem based on what's in your rootfs.

It is identical to the NSA325, even the pinouts! repeat whatever you did with the NSA325.

In the mean time, what you should do is making sure your fstab is matching with your setup. If you have updated to Debian stretch, it's important to have the root device identified with label. Especially since you have multiple partition on your disk.

cat etc/fstab
LABEL=rootfs      /               ext3    noatime,errors=remount-ro 0 1

So modify that and boot again. Observe and write down the LEDs light behavior (this also give out hints).

Cool, I found my thread ;)

I connected the serial console since setting "LABEL=rootfs" in fstab did not help.

I found there were some variables not set, after setting them directly in uboot, i could boot from my small 160GB test harddisk.

But there is a problem initializing my big 3TB harddrive, in uboot I cannot initialize it:

Net:   
|  port  | Interface | PHY address  |
|--------|-----------|--------------|
| egiga0 |   RGMII   |     0x01     |
egiga0 [PRIME]
Hit any key to stop autoboot:  0 
Marvell>> mw.l f1018100 20420000; mw.l f1018140 003ca800; sleep 3; scsi init
AHCI init for unit0
Target spinup took 0 ms.
SATA link 1 timeout.

Error: SCSI Controller(s) 1B4B:9215 1B4B:9235 not found
scanning bus for devices...

I tried with "sleep x" for x=0 to x=5 but it stays at "scanning bus for devices" and nothing else happens.

Oh boy, don't tell me the harddrive is not compatible ;)

Cheers, Peter

Peter,

That error message does show up in boot. But it usually was OK after we see this. Try to list the files on the root partition.

mw.l f1018100 20420000; mw.l f1018140 003ca800; sleep 3; scsi init
ext2ls scsi 0:1 /

Its not about the error message. The command "scsi init" hangs.
The last message is "scanning bus for devices..." but the command does not release the command prompt, it looks like the command crashed.
I tried a second 3TB harddrive but it is the same.

Peter,

Ah. That's new to me. Usually we see the message, but it got pass that and recognizedthe HDD. Perhaps this stock u-boot does not support >2TB capacity disk. But even that should not hang or crash. It should get pass the error and keep running.

I will need to either try it myself or look at the source code. I've tested with <= 2TB HDD only.
