I've decided to try out Ubuntu 8.10 server on an older machine I have
here. It is a Supermicro P3TDER with a Promise TX4000 raid adapter.
I had previously had a different flavour of Linux installed on it with
several raid arrays created via mdadm. I thought I would leave these as
is, and install Ubuntu into them (i.e. format them as use them for
/boot, /, /usr, /var ...)
While the install itself went fine, the system will not reboot. I get a
message saying that md2 (/dev/md2 - the would be root) does not exist
and then the busybox prompt. Attempting a boot in rescue mode goes a
little further but says that all the arrays are "stopped". I've tried
experimenting with "rootdelay" in the grub config, but to no avail. It
looks as tho I have RAID and Promise SATA loaded (looking at /proc/modules).
I figured that I may have corrupted the arrays somehow, so I booted from
the cd, and picked "rescue broken installation", and from there "create
a shell on root" - and chose /dev/md2 as root. This works fine, I can
mount all the other filesystems successfully as well.
I have /boot as ext3 but everything else is xfs.
