hello there

My old hard drive in which is running slackware 10.0 is now so noisy
with high frequency. I now wanna move whole contents in the old to a new
harddisk. Please tell me your experience about that
much appreciated,
regards
d.phan
my system: slackware 10 (ker-2.4.26/cpu 450mhz - 128MB ram) with no X
and X apps, and managed by puTTY (ssh) from XP clients

1) cpio the entire drive to the new one. Make sure the layout is the same,
if /dev/Xa1 is the swap on the old drive, then it is the same on the new.
2) Boot up either by bootdisk or through the CD with the new drive on the
same channel as the old
3) Mount the slice, and use chroot to set it to the root slice
4) Run lilo

You may need to edit your fstab if you add or remove mount points and
slices.

That should be enough though.

First, excellent idea to move your data. If it sounds bad, there is a high
likelihood of impending failure!

I would reiterate, make sure the physical layout looks the same after the
data transfer. i.e. hda should be replaced by hda (not hdb).

This also makes me wonder, because I have considered using LVM (Logical
Volume Management, for several physical disks)... am I correct in my
understanding that under LVM, the provided tools can be used to move the
data off the existing physical disk, and then back on to a new disk without
risking corruption in the process?

You may want to take a look at BackupEdge http://www.microlite.com/
Fully functional evaluation download, allows for restoration to
differing HD subsystems if you think you may be going that route (eg.
SCSI to IDE).

Theres a howto that covers this issue here:

This area is designed to become quite warm during normal operation.

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).

Should be published as Mini-HOWTO for *every* OS.

`tar` does not recreate /dev properly, the last time I looked.

GNU tar does. I've done complete network transfers of disk contents
using tar and netcat.

Aren't there also some other things that could be happening with /proc and
/dev, like dynamic content creation? I can't remember the details but I
thought I'd throw that out there.
