Hey ppl:
I'm currently trying to install Lenny AMD64 502a in a
Intel Xeon Q8200 8Gb Ram, with 4 Sata2 500Gb Discs. Problem is that
after finishing partitioning and installing the Harware, Lilo or
Grub wont install, Lilo Reports Error Code '1' which makes no sence
since its an error related by the bios accessing the disk which
shuld be /dev/md0.
I dont have much expirience with RAID so not shure
whats wrong here, any lead would be great.
AFAIK you still can't boot straight from software RAID 5 or 10 (I
guessed that is what you're using). You'll need a small slice on every
disk, setup as software RAID 1 for /boot. The rest can be placed in
the RAID 5 or 10 partitions. Lilo can't see the disc /dev/md0 at boot
since it has no way of assembling the array. The kernel needs to be
booted first. When using RAID1, no array needs to be assembled, since
they are indentical copies. The boot manager can use the first disk it
finds.
Mayby the latest LILO of GRUB2 can handle /boot on RAID other than
RAID1, last time I searched I only found support for /boot on lvm, not
RAID5
