> 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?
