Re: [opensuse] boot after installation problem

Hi Folks,

I'm having a problem installing 10.3 x86_64 on a box with
many raid disk controllers and disks. It has two disks
mounted in the back that are supposed to be the system
disks, configured as a raid1 mirror. Alas, this disk
shows up after all the other disks, in this particular
case as /dev/sde instead of /dev/sda.

In general, if you want the system disks mirrored in
hardware RAID, then you should get a motherboard which
has a RAID controller on it.



A full install goes well until the first boot. The boot
fails saying it can't find /dev/sde3 (the root partition).
It eventually drops into a limited sh shell running out
of ram.

Not surprising. If the module for the RAID card isn't
in the initrd, then you're not going to boot successfully.


This box worked ok when the system disk appeared as /dev/sdc.
I wonder if there is some bug about booting from disks too
far removed from /dev/sda?

Probably.


I've got a call in to the manufacturer to see if there's
a way to have the system disks show up as /dev/sda, but
no word from them yet.

At this point, I would say, re-arrange your disks, and
use software RAID until you can find a motherboard which
has built-in hardware raid for /dev/sda and /dev/sdb.
It will eliminate a lot of headaches.


Anyone seen this behavior? The controllers are 3-Ware,
the disks SATA, if that matters.
