Hello,
I'm using FC4 as a base for an embedded instrument. When the instrument
goes out the door, it has a 256 MB flash card for the hard drive, and a
Pentium 4M motherboard. Also, there will never be a keyboard, nor a
monitor.
During development, there is a SATA hard drive with all of FC4 on it,
and it is currently using LVM.
My task is to prepare a bootable, flash card. Next remove the hard drive
and have the system work.
Here is what I do:
1) fdisk /dev/hdc (the flash card is hdc)
2) In fdisk, create a single large linux partition (don't need any swap
space) and active this partition.
Create the file system
3) mke2fs /dev/hdc1
4) tune2fs -c 0 /dev/hdc1
5)Copy over the files I need (I'll give a set if you want, but its
enough to make linux happy).
6)copy over my custom rc.sysinit, since I want to have exact control
over how the system boots
7) Install grub. I'll give the details:
grup --no-floppy
device (hd0) /dev/hdc
root (hd0,0)
setup (hd0)
8) Grup is happy. And says so
9) Edit grub.conf so the kernel is at /boot/.....
10) Edit the fstab to mount /dev/hdc1 on /
Turn the power off, and remove the SATA hard drive:
Now the problem
Grub starts, and finds my kernel
The kernel starts.
Redhat nash starts. Then I get the following messages.
Reading all physical volumes. This may take a while...
Aborting - please provide new pathname for what used to be /dev/hdc1
No volume groups found
Unable to find volume group "VolGroup00"
ERROR: /bin/lvm exited abnormally with value 5

Kernel panic - not syncing: Attempted to kill init!
I see it is asking about VolGroup00. This is LVM stuff. I don't want LVM
on the card. What is really weird is that all of this is happening
before the rc.sysinit is started. I don't find any command line options
to the kernel to turn LVM off. All of the LVM options are "modules" when
I built my kernel.
So my question is quite simply,
What do I have to do so that LVM is NOT used?? Any other options?
