[linux-lvm] root fs on lvm - kernel panic

[jkcwong at mail.hongkong.com]

the actual error i have now copied down:

VFS: Cannot open root device "3a00" or 3a:00.
Please append a correct "root=" boot option

Kernel panic: VFS: Unable to mount root fs on 3a:00

a few lines above this error i see a line that reads:

Partition check:
Floppy drive(s)
FDC0
LVM version 1.05 (15/07/2002)

i guess it can actually read the /etc/fstab?  which i have a line that reads "root=/dev/vg00/lvol0"

if my root is not on lvm, just say, /home and /usr are on lvm, then it works fine.  i have inserted the following to my rc.sysinit:

if [ -e /proc -a -x /sbin/vgchange -a -f /etc/lvmtab ]; then
  action "Setting up LVM" /sbin/vgscan
  action "Initialising LVM" /sbin/vgchange -a y
fi


i have tried to move the /etc/fstab and /etc/lilo.conf to /boot (not on lvm) and then create sym links to them.  then initrd / lvmcreate_initrd and adjust lilo.conf.... same result.  please help.  thanks.
