Slackware 14.1 hardware RAID1 won't boot
 
Hi all

Ive been using Linux a couple of years ago and yesterday i made an effort at a comeback.
Ive been using Slackware back in the day with about distro version 7.x :)

On to my issue at hand:

I have a hardware raid setup for RAID1. (works fine in windows, checked my disks and no errors found)

on booting with the Slackware 14.1 install DVD it finds /dev/md126 and /dev/md127 and then goes on to find the actual name wich i joined my 2 harddrives together as in raid bios: "Volume0" (i also get a /dev/md/Volume0)

I also get a /dev/sda1 wich is the only one of these three /dev alternatives that seems to have write access so i guess that is my raid volume?

I go on to install my system. Goes fine to format and install the packages but when it comes to Lilo i cant get it to work.

Lilo says "File system would get destroyed with lilo boot sector"

The filesystem i formatted as is ext4 on the partition in cfdisk (also tried Raid auto detect on partition in cfdisk with formatting as ext4 with same errors)

I cant seem to figure out what im doing wrong.

Any advice fellow Linuxers?

This 'n That
 
Since no one else has responded I'll mention of few things that may (or may not) be helpful.

Many times hardware RAID is "fake RAID" and requires MS Windows software to function.

If you have true hardware RAID that doesn't require MS Windows software then you should be able to just refer to the single RAID device (/dev/md/Volume0) when installing Slackware and not be concerned about /dev/sdax or /dev/sdbx.

The hardware RAID may require a device driver (for example an Adaptec driver) that must be built into in initrd for the system to boot. See ...

man mkinitrd and /usr/share/mkinitrd_command_generator.sh
man lspci (lspci -v)

I haven't used hardware RAID for more than a decade so there are probably other obvious issues I've forgotten.


If ultimately you can't get hardware RAID to work you can use software RAID available in Linux. See man mdadm and the documentation files on the installation disk such as ...
