at the moment i have boot=/dev/hda, that i can boot at least from the
harddrive, but when i booted from floppy (as i wrote from in my other
mail) even then i couldn't raidhotadd /dev/hda1, 'cause it had active
inodes, according to log. how could it have active inodes, when it was set
to failed dik in the raidtab, and i booted from floppy?



~ # cat /etc/lilo.conf
disk    = /dev/hda
  bios  = 0x80
disk    = /dev/hdb
  bios  = 0x81
disk    = /dev/sda
  bios  = 0x82
boot    = /dev/hda

i do not have initrd.

this is getting somewhat weird:

~ # cat /proc/mounts
/dev/root / ext2 rw 0 0
proc /proc proc rw 0 0
devpts /dev/pts devpts rw 0 0
/dev/sda3 /oradata ext2 rw 0 0
/dev/sda2 /orapps ext2 rw 0 0
/dev/md4 /opt ext2 rw 0 0
/dev/md3 /var ext2 rw 0 0
/dev/md2 /usr ext2 rw 0 0
/dev/md1 /mnt ext2 rw 0 0

~ # mount /dev/md1 /
~ # cat /proc/mounts
/dev/root / ext2 rw 0 0
proc /proc proc rw 0 0
devpts /dev/pts devpts rw 0 0
/dev/sda3 /oradata ext2 rw 0 0
/dev/sda2 /orapps ext2 rw 0 0
/dev/md4 /opt ext2 rw 0 0
/dev/md3 /var ext2 rw 0 0
/dev/md2 /usr ext2 rw 0 0
/dev/md1 /mnt ext2 rw 0 0
/dev/md1 / ext2 rw 0 0
~ # mount /dev/hda1 /
~ # mount /dev/hda2 /

and so on...

~ # mount
/dev/md1 on / type ext2 (rw)
proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw)
/dev/sda3 on /oradata type ext2 (rw)
/dev/sda2 on /orapps type ext2 (rw)
/dev/md4 on /opt type ext2 (rw)
/dev/md3 on /var type ext2 (rw)
/dev/md2 on /usr type ext2 (rw)
/dev/md1 on /mnt type ext2 (rw)
/dev/md1 on / type ext2 (rw)
/dev/hda1 on / type ext2 (rw)
/dev/hda2 on / type ext2 (rw)

?!?

something like this i haven't seen yet, and just can hope that im not
going to see anymore...
