i assume box has one old drive, hda;
i assume box has cabling to attach two drives;
i assume you have bootable floppy or cdrom ready.
test boot it to be certain.


(1) shutdown.  add the new drive into the box.
cable and jumper as needed.  for example i will call it hdb.
don't change anything else.

(2) reboot. use dmesg to verify that linux sees the new drive.

(3) fdisk, mkfs and mkswap on new drive as desired.
new partitioning scheme should resemble old scheme, but does
not need to be identical.  order of partitions should not be
altered (so as to keep procedure simple).
for example, if old drive has:
	hda1 as 256MB swap
	hda2 as 2GB /
	hda3 as 2GB /tmp
	hda4 as extended
	hda5 as 14GB /home
then new drive might have:
	hdb1 as 512MB swap
	hdb2 as 4GB /
	hdb3 as 4GB /tmp
	hdb4 as extended
	hdb5 as 32GB /home
if adding a larger drive, and uncertain about partitioning schemes,
then just leave additional space unused.  it can be added in later.

(4) mdir new mountpoints and mount partitions as needed.
for example:
	mkdir /mnt/hdb2
	mount /dev/hdb2 /mnt/hdb2
	mkdir /mnt/hdb3
	mount /dev/hdb3 /mnt/hdb3
	mkdir /mnt/hdb5
	mount /dev/hdb5 /mnt/hdb5

(5) use tar to copy live data from old mountpoints to new mountpoints.
for example:

	OLDMNT=/
	NEWMNT=hdb2
	cd ${OLDMNT}
	tar --one-file-system -cpvf - . | ( cd ${NEWMNT} ; tar -xpf - )

repeat as needed (eg., /tmp and hdb3, /home and hdb5, ...)
you can switch to another console and check progress using 'df'.


(6) shutdown.  disconnect old drive.  cable and jumper new drive
as hda.  save old drive until system is verified running new drive.
if procedure fails then system can be restored by replacing new
drive with old drive.


(7) say prayers.  boot from floppy or cdrom.
use lilo bootprompt to mount filesystem from new drive.
for example:
	boot: mount root=/dev/hda2

(8) run lilo to make new drive bootable.

(9) shutdown, remove cd or floppy, reboot using new drive.
verify everything is working.
fill new drive up with lots of new stuff until full.
buy bigger drive.
goto (1).
