SMART is saying that one of my hard drives is an accident waiting to
happen and that I should replace it. No worries there, as I have two
160gb hard drives just sitting around in an unused box I was going to
cannibalize anyway. But it does have / and /home on it, so what would
be the best way to go about doing this? I think I have an IDE slot to
plug in the new drive, or at least I could temporarily replace my
CD or something.
I assume I would want to use dd or something?
If they are the same size, dd is perfect.
Otherwise, rsync is a good choice as well. But -a (as mentioned by
Pete) is not sufficient, it looses hard links. Therefore, you
should add at least -H and do the rsync file-system wise (otherwise
the hard-link detection will fail).
Of course, you can also use
find -xdev $src_dir | cpio -pdmuV $dest_dir
For local file tree copies, cpio is a fast true-and-tried method.
You probably don't want to replace your CD, as you need it to boot
the rescue system from the SUSE DVD, which you will use to copy /.
Try to avoid copying / from an active system.
Don't forget to grub --install the new disk afterwards, otherwise
you won't be able to boot from it.
Good luck,
Joachim
PS: That's the reason why all my systems use Software mirroring
with md, even if there's only one disk in it. (Well, most have two
mirrored disks anyhow -- disk prices are so low today.) If I need
to replace the disk, I have almost no outage, this can be done with
mdadm during normal usage, except for the very short time to put
the disk into the chassis.
