Hi Everyone
I have a 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:
vgscan -- no volume groups found
VFS: Cannot open root device "vg1/root" or 00:00
Please append a correct "root=" boot option
Kernel panic
When I boot this ramdisk I don't see it loading the SCSI modules anywhere.
I'm sure this has something to do with this. How does the ramdisk store the
modules for this?
Please help. This is very frustrating and very urgent. I am not sure what
I'm doing wrong.
Thanks
Brendon
