[NCLUG] hard disk copy

[Gabriel L. Somlo]

I'd try dump and restore (dump.sourceforge.net):

mke2fs -j /dev/hdg1
mke2fs -j /dev/hdg2

mount /dev/hdg1 /tmp/foo
mount /dev/hdg2 /tmp/bar

cd /tmp/foo
dump 0f - /dev/hde1 | restore rf -

cd /tmp/bar
dump 0f - /dev/hde2 | restore rf - 

Once you put the new disks in place, you need to boot your system from
a floppy, and install the bootloader (I don't know a
lot about grub, but with lilo all you'd have to do is run it:
/sbin/lilo). After this you should no longer need the floppy to boot.

dump.sourceforge.net has statically linked binaries for dump and
restore, which you could put on a second floppy if they don't fit on
your rescue image. Alternatively, you could use a CD to boot -- let me
know if you want mine, but there should be a lot of CD distros out
there that include dump and restore...

Hope this helps,

Gabriel
