[linux-lvm] Error when trying to change root to LVM



Hi Everyone

I have an old IBM server 320. I need to create a volume group as there is
not enough space to perform upgrades etc.
As I can only only do a text install and you cannot create Logical Volumes
in the text install, i have installed the OS on one of the 2 gig drives in
the machine. I then go about trying to create an LVM etc. (Please remember
that these are SCSI drives)
I manage to create a volume group on the remaining 2 drives and then create
a logical volume on these. I then mount this as an ext3 and copy the entire
os over using find / -xdev | cpio -pvmd /mnt
This all works fine. I then run lvmcreate_initrd to create a new ramdisk. I
go to my boot which is on a different partition and edit grub.conf so that
it reflects the ramdisk and i change the kernel parameter to point to the
logical volume ie. /dev/vg1/root
I also edit the fstab so that the /dev/vg1/root is mounted as /.
I then reboot and get the following error:
Mounting root filesystem
Mount: error 6 mounting ext3
pivotroot: pivot_root(/sysroot,/sysroot/initrd) failed: 2
umount /initrd/proc failed: 2
Freeing unused kernel memory: 120k freed
Kernel pani: No init found. Try passing init=option to kernel.

I have checked and there is a initrd directory in the Logical volume as I
copied the entire root. I have noticed that it doesnt seem to initialise the
logical volume before it tries to mount the root filesystem. Is this right?
How do I get it to do this?

Thanks
