Moving LFS to a new drive


I am glad to say that after following the instructions in the LFS book, I was able to get the system built and running the first time out. Because I followed the instructions, the LFS files are on a partition of drive /dev/hda. I would like to move it to /dev/sd?. So far I have tried tarring everything and untarring it on the new drive without success. I've also tried a direct copy also with no success.

What am I missing here? TIA for your assistance!

did you try ........
Code:
cp -Rav * /dev/sd?
make sure your in the LFS directory itself.........the * means all files get copied....... -Rav ......is recursive,attributes,verbose

Just a slight correction:

The -a option stands for archive, not attributes, and is equivalent to -dpR.

So you don't need to use both the -a and -R options together.

The correct command is: cp -av * /dev/sd?

Enjoy!

[edit] Doh! Just noticed an even bigger glitch: First you should run:

mount /dev/sd? /mnt

then

cp -av * /mnt/

[/edit]

The problem could be the active filesystems mounted on /dev /proc and /sys. Also, if you have X running there will be some sockets in /tmp that may cause you problems. I've had good results working from the host system. Reboot into the system you built lfs from, login as root and (assuming you have it mounted on /mnt/lfs)

cd /mnt
rm -rf lfs/tmp/*
tar cjf lfs.tar.bz2 lfs

that tar command may take a while but at the end of it you'll have a backup copy of your lfs system that should be small enough to burn onto a CD. I used this to take an lfs system from one computer to another. Obviously, I needed a host system to untar it on the target machine. I then had to edit /etc/fstab, change /etc/X11/XF86Config and recompile the kernel but it worked really well. It was a lot easier than building LFS on the new computer. Both machines were Pentium 4's. It probably won't work for different architectures.
Anyway, after you've tar'd up lfs, umount /mnt/lfs, mount the new drive you want lfs on and then untar it again

tar xjfp lfs.tar.bz2

that will uncompress it into the lfs folder. Whatever is mounted on /mnt/lfs will get it. The p option preserves the permissions, so I'm told.

/dev/sd? suggests that your destination is a scsi-disc...

That would mean: the kernel you are trying to boot from there needs to have scsi-support compiled in! !Not as a module!
There may be other ways like using an initrd, but I can't help you with that - compiling in scsi is the easiest way.
Of course you would need to adjust yout /etc/fstab to reflect the layout of the new disc - all the names of the partitions would change from /dev/hd? to /dev/sd? ...
You'll need to create the partitions and make the filesystems you want to use _before_ you try to

1.) mount the partition (with the rigtht options for creating all the files with the original permissions)
and 2.) copy every partition to their new destination - in your case probably only one

Have a boot-medium ready from which you can boot into the new OS (on the new disk)
You can install the boot-manager from inside your "old" System, but I cannot give you exact hints on that right now - please search for instructions to do this - I have done this several times with no problem - but always from ata to ata (IDE-Disks) - but the only difference scould be the needed changes to /etc/fstab

If you cannot figure it out, I could try to reproduce the way I did it - I've been and I'm using lilo to boot 2 diffrent linux'es and WinXP without any problems.

Greetings

Jochen

Addition: it is all described in great detail in an excellent mini-howto called:
Hard Disk Upgrade Mini How-To

Im not sure where to find it, but this shold not prove difficult...
I could even send you the copy I have here if needed

I use cp -avx / /mnt/disk

-v verbose

-a keeps permisions and does a recursive copy. It handles /dev
cp /dev/hda1 . gives a large file with the contents of hda1
cp -a /dev/hda1 . copies the device to the current directory

-x stay on the same filesystem. Ignores any mounts eg /proc /sys

Did you update your /etc/fstab and /boot/grub/menu.lst?
