[root=/dev/md1 not working]

Update - I am getting closer :)


One reason why it did not work here was that I had to create
the initrd in chroot (the mounted md-devices the original system got
copied to), this was it got /dev/md*, raidmodules and
other things needed to get raid running into the initrd.

I did not even have to change the partition type to autodetect, since
raidstart and such are available and get started in the created initrd.

(master = first ide controller, secondary = second IDE controller, no
master/slave hdd)

But now I am stuck and booting while simulating a broken secondary IDE
controller.

If I take off the master cable (powered off of course) I can boot into
the raid - and get the following messages:

md: could not lock [dev 03:03] sero-size? Marking faulty
md: could not import [dev 03:03], trying to mount raid nevertheless
md: autorun
...
former device [dev 03:03] is unavailable, removing from array
...

So it just ignores hda and boots into the remaining mirrored hdc.

But after rebuilding the raidset and removing the cable to the secondary
controller i get:

ide0 on 0x1f0-0x1f7, 0x 3f6 on IRQ14
md: could not lock [dev 16:03] sero-size? Marking faulty
md: could not import [dev 16:03]
md: autostart [dev 16:03] failed
/dev/md1: invalid argument
...
Kernel panic, because of missing root.

To fix I've tried to make the partitions raid-autodetect, created a new
initrd (because the old one still had "failed-disk" in it) and finally
added "
        disk=/dev/hda
        bios=0x80
        disk=/dev/hdc
        bios=0x80
" to lilo.conf.

with no luck - Why does it not "try to mount raid nevertheless" this
way?
