Quoting Mike Wyatt <[EMAIL PROTECTED]>:
yesterday I tried installing Debian onto a raid0 array using this
guide <http://tnt.aufbix.org/linux/raid/>, but it quickly became too
overwhelming for me, so I quit the installation and went through an
installation like I always have (netinstall from woody floppies).
everything installs fine, but when the computer reboots to start
base-config, it stops and says "operating system not found"
the bios is setup correctly. it autodetects the hard drive just fine,
and the boot order is hard disk -> floppy -> cdrom. I used the rescue
floppy to apt-get install grub, removed lilo, and properly installed
and updated grub in hopes that would fix anything, but I still got the
same "operating system not found" error.
then I read that lilo and grub don't support booting from a raid0
array. which is the only thing I can think of that would be causing
this problem.
the only thing is, while yes the first tiem I tried installing onto
the raid array and I did get to the mkraid /dev/md0 step, it was after
that I aborted and started the installation again. I repartitioned the
primary hard disk and installed as normal. since this was a software
raid I thought that any traces of anything would be gone with a
repartition and new filesystems put in place. is that a wrong
assumption?
basically, is there any way to reverse the steps of a software raid0 array?
Fdisking the disk should remove any traces of a software raid.
You might have to zero the mbr too.
Have you tried the sarge installer? It has built in raid support for
the install.
You can install on a raid 0, but /boot needs to be mounted as a disk or
raid 1.
Cheers,
Mike
