root image

[Stephen J. Stuczynski]

My Root partition is getting full. I purchased a larger drive and would like to
do an image dump to the new drive and be able to boot to it. Does anyone know
of a way to do this. I looked for the dump command, but couldn't find it.

Thanks,
Steve

I think you may be able to do this with the dd command. Something like:

dd < /dev/hda1 > /dev/hdb1

However, please don't try this unless you have a backup and are ready to
use it.

That will work, but you will probably not be pleased with the result. What
you would end up with is a duplicate of the original filesystem on the larger
drive partition. That sounds like what you want at first, until you realize
that the filesystem is still the same "size" that it was before. The "new"
space at the end of the partition is unused. What you need to do is to
make a new filesystem on the new partition and copy the directory heirarchy
to the new filesystem. You will also need to arrange to set up LILO on the
new disk so that you can boot from it.

That is always good advice.

You look for dd. Try 'dd bs=512 if=/dev/oldpartition of=/dev/newpartition'.
The partitions should be of the same size. Afterwoods you have to reinstall
lilo to be able to boot the system.

BTW why don't you try the following?
- boot a floppy system with ramdisk
- mkdir /tmp/old/; mkdir /tmp/new
- mount -t?? /dev/oldpartition /tmp/old
- mount -t?? /dev/newpartition /tmp/new
- cp --preserve --recursive --no-dereference /tmp/old /tmp/new
- reinstall lilo

This should also do some defragmentation to your drive :-) .

I thought about that and kept wondering why he was asking for the dump
command. However he sounded like he knew more about *nix than I so
I just looked for the closest think to what he was asking about.
I've had no trouble learning the fdisk, mkfs (mkefs2), mount
sequence -- but I'm still a little sketchy on the tar/cpio switches
(makes me almost long for the stupid simplicty of MS-DOG's XCOPY)

Say, Is anyone out there willing to make a bash script that
gives us DOS converts the equivalent behaviour of XCOPY through
cpio? Make it a whole collection of aliases and scripts (with
support for the same switches -- except we'll use the dash character
and not allow the '/' for those).

Under DOS (4DOS) I've long since aliased copy to cp and move to mv
(and dir /4vp to simply .) because their shorter and I've gotten used
to them. Under bash I alias clear to cls.

And I always repeat it. Sometimes I even follow it.
