 Posted: Sun Nov 23, 2003 4:30 pm Post subject: after i created initrd to have LVM and HW RAID support .... |
 |
|
on my highpoint controller, mine hid.o module wont insert.
back to my configuration.
i have 2 gentoo systems. first is on /dev/hda3 second on /dev/main/root (lvm)
i have 3 disks on my highpoint controller and 1 on motherboard controller. 2 disk on highpoint form hw raid1 drive, on which i have 2 partitions, sda1-ext2-/boot and sda2-lvm. root partition uses 12GB of that lvm space.
so, in order to boot i had to create initrd which will have hpt37x2.o driver and vgscan and vgchange to recognize root partition.
while gentoo system on hda3 uses same kernel and modules as the other on lvm space and works ok, gentoo on /dev/main/root wont insert hid.o
so i tried to put hid support into kernel, but it crashes while compiling hid.
strange isnt it?
my guess is that i have created "strange" initrd  . here is how i create initrd
im not mentioning that installing grub on /boot partition destroys raid1 (thats another story, after i install grub it stops on stage 1.5 i think)
