 I've just tryed to get RAID1 going on another non-cobalt host, and I seem
to be doing something simple wrong, as I get something quite similar here
too:

[root@jny02 /root]# raidhotadd  /dev/md0 /dev/hda5
/dev/md0: can not hot-add disk: invalid argument.
md: trying to hot-add hda5 to md0 ... 
md: can not import hda5, has active inodes!
md: error, md_import_device() returned -16
[root@jny02 /root]# mount
/dev/md0 on / type ext2 (rw)
none on /proc type proc (rw)
/dev/hda1 on /boot type ext2 (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
 
 This is likely because to get it to boot, like the cobalt, I'm actually
passing root=/dev/hda5 to the kernel, not /dev/md0. 

 When I used "root=/dev/md0", the kernel booted, mounted root, and then
moaned that it couldn't find init (so I had to wonder what filesystem it
ended up mounting). I tryed to setup my lilo.conf from;
    http://www.tldp.org/HOWTO/mini/Boot+Root+Raid+LILO-5.html
but because I don't quite understand what it's doing, I could be doing
something wrong:

 My lilo.conf is:

boot=/dev/hda
map=/boot/map
install=/boot/boot.b
linear
disk=/dev/md0
    bios=0x80
    sectors=63
    heads=255
    cylinders=5005
partition=/dev/md1
    start=63
image=/boot/bzImage
    label=2.4.18
    read-only
    root=/dev/md0

 Is there anything obviously wrong with that ?
