I am finally at the point I want to give up my old external scsi hard
drives.  Unfrotunately, my current /, /usr, /home, etc all exist on scsi
drives.

I recently purchased a 60 gig hard drive (ide) and have now installed it.

What is the best way to move all of the files and directories, and special
device files, and etc from the scsi drive to new partitions on the IDE
drives?

Can I simply use a recursive "cp" with -a?  Should I use "tar"?  What
about "parted" and its partition copies?

Or is there some way I can run an linux distribution installer from within
linux and make it install to the ide drive instead of the scsi?

Or is there some way to make "rpm" nicely redirect where it installs
things?


In fact, with som much space, I would love to have Debian, SuSE, and
YellowDog distribution sets so I can run and test OpenOffice.org against
those distributions easily (shared build drives) with different
distribution installations.

This is my last step to get a working system so any hints on the best way
to move so much data (and special device files) from one partition to
another preserving the owner,group,word, permissions, file ownership,
setuid root bits, etc. would be greatly appreciated.

I've done this several times, to install xfs support on live machines
(ie. on my desktop and laptop that were already full of crap junk and
other kind of files).

rsync -av --exclude /proc --exclude /home/ / /newroot/

Exclude every mount point from the rsync and do this for every
partition. Best is to do this from a separate root, or a rescue/boot
disk, in which case rsync -av /oldroot/ /newroot/ is easy enough without
having to care.

I _think:
rsync -av -x / /newroot/
will get just the / partition (-x means one fs, cp and a few others take
this arg).

the man page has it indeed. The good thing is that you can run it
multiple times, or stop it in the middle and restart where you left off,
which you can't with the other solutions.

Cheers
