[gentoo-user] Moving installation to another HD

[Daniel da Veiga]

Hello list,

I've had Gentoo running for a long time now, before that I was using
WinXP (this is my work machine, I have no choice). I simply got an old
(8GB) HD, setup it, installed and started working (with dual boot,
just in case). After a while, I found myself not using winxp anymore,
as most of my stuff was already ported (printers, file shares) or
emulated (novell using qemu and full virtualization). Now, I'm running
out of space in this old HD, and want to move my Gentoo install over
to the 40GB original disk of this machine.

I thought about "dd" the entire old disk to the new one, but I guess
partitioning will not like that (because of the size, and I have been
using fixed primary partitions), maybe tar or something like that.
Anyway, if anyone have suggestions on the procedure needed to do that,
it would be more than welcome. Any info needed, please let me know.

Thanks in advance.

* Boot from a live-CD
* mount old and new drive partitions
* cd to the mountpoint containing the data to be copied
* tar -cSp --numeric-owner -f - . | ( cd /mnt/NEW && tar xSpvf - )
* Drink coffee :)

Worked for me more than once.

Thanks Cristopher. I'll give it a try tomorrow morning.

I always boot from the CD, mount both drives as above then do a cp -av
/old/stuff/ new/stuff and it works.  No tarring and such then.  Still
get to drink a cup of coffee though.  O_O

The one thing you may have to take care of is grub, since I assume the
/boot directory will be moving to the 40G drive as well.  Assuming the
partition containing /boot is /dev/hda1, then the following should
work:

echo "(hd0) /dev/hda" > device.map
grub --device-map=device.map << EOF
root (hd0,0)
setup (hd0)
quit
EOF

huh, true, I forgot Grub. I usually chroot to the new boot partition and 
reinstall grub just based on the old configuration files (though it 
will only work if the partition scheme hasn't changed).

You seem to have read my mind, I was just about to ask about the boot
signature and if I should run grub again. Yes, I'm moving the whole
partition scheme along with data.

Linux "cp" is a powerful command, gotta take a look at its manual.

Thanks for the info so far people, I've decided to move my stuff by
the morning, I'll post any disaster/sucess reports.

Also don't forget to adjust fstab and your kernel line in grub.conf.
