[Watford] Ghosting a Linux HDD

[walt]

I'll go with Alain's instructions first and then I'll have a go at Yvan's
way of doing things.

OK, I  have partitioned a new drive (/dev/hda), then setup a folder named
new-drive (in /dev/sda2) and now I want to mount a partition on the new
drive: /dev/hda2.

The command 'mount /dev/hda2 /dev/sda3/new-drive' keeps generating error:
	'/dev/sda3/new-drive' is not a directory

And I have no idea why because it is.  I have copied stuff into it from a
console and from KDE. I have also checked the permissions which are 'full
control' eg read write modify etc etc.

Any ideas?

Thanks Walter.

Depends on quite what you are doing, but I would:

1) partition the new disk (fdisk)
2) make new file systems (mkfs)
3) mount them up - will need to create mount points in the RFS first

You prob need to do the above from a Linux Live CD of some sort.

Copying data over, lots of ways:

a) rsync - if you have a network connection
b) tar to create archives, copy the archives, untar

The above will get an image across, but it won't boot. To do that you need
to:

1) Get a shell under the newly copied system, something like:
	chroot /mnt/system /bin/bash

2) Install grub, something like:
	# grub
        grub> device (hd0) /dev/hda
        grub> root (hd0,0)
        grub> setup (hd0)
