Boot from USB while SATA disks connected
April 28, 2013 02:02PM
Hi,

i'm using a GoFlexHome with 3.1.10-17-ARCH. The OS is installed on a USB-Stick (ext2). For the databackup, I want to use two 3,5" hd-drives as raid 1, too.

Cause i use 3,5" disk, i use a extra power supply for the disks. So i can switch the disks, during the boot process on! After i set the disks into the raid1, i must use for a working bootprocess, the following steps:
* Switch off the power supply for the disks
* Reboot/switch on the GoFlex
* Wait for finished uboot (the led becomes on)
* Switch on the power supply for the disks

If i don't switch the power supply of the disks during the boot process on, the boot fails. See the log! If the disks on the beginning of the bootprocess on, the boot fails too!

My google search told me, that i must use disklabel for working booting. I used tunefs to give my stick the label "rootfs" and changed the usb_init entry in my env!

fw_setenv usb_init "run usb_scan; setenv usb_root LABEL=rootfs"

But the booting problem is still alive.

The boot log is always the same:

A little edit:

I'm using a GoFlexNet, not GoFlexHome!

Marcel,

You should get the latest rootfs at Arch site and put it on a EXT3 stick, boot with it without the SATA drives connected. After it booted up, plug in the SATA drives. After verifying that this works, post back and we'll help to set the envs correctly to enable booting while SATA is connect.

I also notice you're running older uBoot. You might want to reinstall to get the latest uBoot (but worry about it later).

Hi, 
setenv usb_root LABEL=rootfs
doesn't work, as it is altered during boot when running usb_scan. You need to hardcode it in usb_set_bootargs
