Clone QNX/POSIX HDD via Acronis or Norton Ghost?
Othersongs
My main question here is a) does anyone know if there is
bootable Unix disc (similar to Acronis or Norton Ghost)
that will do what I want???
Also how about a dedicated Unix newsgroup where I might
have a better chance of getting an accurate Unix answer?
Meaning does anyone know if booting from a bootable disc
of Acronis or Norton Ghost, will permit me to:
1. Clone an existing QNX/POSIX HDD (250GB) to a new 500GB HDD?
(my hunch is that both will permit this)
2. The tougher part may be in how to expand the main partition (on the original
250GB Unix HDD) to become larger and take up most of the new 500GB HDD.
Any/all thoughts on what I'll have to do will be appreciated.
Also, I've so far tried this on the comp.sys.ibm.pc.hardware.storage n/g
with one response by Arno that may (or may not) be all I need:
> <"Size change requires filesystem support. I doubt very
> much that Acronis or Ghost support that for rteh QNX filesystem.

My 2nd question there was:

Arno's response was:

> (cd <new-root-partition>; tar xvf -)">
Thanks in advance for comments/answers

I've never used Acronis or Norton Ghost.
I haven't looked at many of the live linux boot cds, but I'd expect
them all to have the required basic tools to do this.
You have three basic options ...
1) Sector by sector copy of the first hard drive onto the first
250GB followed by resizing the partition/filesystem.
This can create a possible problem with duplicate volume serial
numbers in the mbr, if you plan on using both drives in the same
computer, after the copying. This problem can actually be
a benefit if you have vista installed, as the mbr will be
unchanged.
2) Preallocate a 250GB partition on the new drive, then do a
sector by sector copy of the partition, followed by resizing
the partition/filesystem.
3) Allocate the 500GB partition, format it, and copy the data
from the first drive to the second.
What do you currently have on the hard drive, as in which os, and
which filesystem type (fat or ntfs)?
http://www.justlinux.com/forum/showthread.php?threadid=134457
shows how to do option number 2.
Option 1 is similar to option 2, except that you skip the creating
of the partition, and replace the dd command with
dd if=/dev/hda of=/dev/sda bs=32256
to copy the entire drive, including the first track.
Option 3 can be done with the tar command as suggested by
Arno, or a little simpler using rsync ...
After creating the partition on the new drive, as per the above
article, mount the old and new filesystems ...
mkdir /mnt/old
mount /dev/hda1 -t ntfs /mnt/old
mkdir /mnt/new
mount /dev/hdb1 -t ntfs /mnt/new
rsync -av /mnt/old/ /mnt/new/

I hadn't heard of qnx before. If you've used one of their
filesystems such as qnx6, which I see no mention of in the linux
kernel .config file, I doubt you'll be able to mount the file
system, to do a copy of the data from that partition to another.
The linux kernel source does have qnx4 support available as a
module, so that filesystem should work ok. You may have to load
the module first with "modprobe qnx4".
The sector level copy of the drive or partition should still work,
for qnx6, but you'll have to use qnx utilities to resize the
filesystem, assuming they have such a utility.
