Hello,

I'm trying to install Gentoo on my USB HDD.

I did the installation process as if the USB HDD was an normal Harddisk.

My USB-HDD is /dev/sda.
I mounted /dev/sda5 as / and installed LILO to /dev/sda.

When booting the first time from my USB-HDD, the startup process
interrupts with an error message "Unable to mount root-FS".
The settings in /etc/lilo.conf are definitely correct.

The problem seems to be, that at the point in the startup-procedure when
the Kernel (?) tries to find the root partition, the USB-HDD-partition
/dev/sda5 is not accessible yet?!

Did I miss to include anything into the kernel? (UHCI is already is
included) Did I miss anything else?

BTW: Sorry, english is not my native language... ;-)

Perhaps you missed usb-storage and SCSI disk support?

No, these are included...!

From what I've seen in setting up my USB-HDD the drive is not available
until after the coldplug service is started. I'm not sure if this is due
to the way I have my kernel configured or if it normal behavior on all
systems. I ran into other issues having my drive connected at boot time
(my mp3 player requires multiple LUNs but if my Seagate USB-HDD is
powered on at boot time it shows up with multiple LUNs and performance is
severely degraded) so I just use auto-fs and keep system partitions on my
IDE drive and data only on my USB-HDD.

I know it's not much help, but thought it might give you some place to
start looking.

There's a howto here: http://www.simonf.com/usb/.
There are no specific instructions for gentoo but for FC3,
FC4, debian, etc). I havn't tried it, though it's on my TODO list.

hope it helps,
Dieter

Have you tried building an initrd with those drivers in it, just in case?

"Included" as in compiled into the kernel and not modules?
