It will not work if the drives are in raid

Don't know if that is really true ... Anyway: Install a minimal system and then rsync everything over.

I always prefer dump(8) and restore(8) via nc(1). All those programs are available from a CentOS boot cd. But be aware that this makes a full clone with all the possible crap and leftovers which might be hanging around on your system.

So I tend to do an appropriate install of the new machine, and selectively copy configuration files and the data I know I want and install the packages I need. Yes, it's a bit more work than just cloning, but also a good opportunity to get rid of old ballast.

Frank,

I would prefer installing new server but sometimes (i.e. when you take over some servers) you don't have enough time to carefully select what should and what shouldn't be copied.

for list purposes, would you consider sharing a script that shows what to sync and what *not* to sync

:-)

I usually sync everything except /dev, /sys, /proc

However, you will also need to edit /etc/fstab and /boot/grub/grub.conf if the disk configurations are different.

You also might need to edit /etc/hosts and /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-eth* to change IP addresses.

or update before the sync and then leave out /boot as well.

I've tried g4u as well, same thing there. It doesn't see raid arrays as well.

I had reason to try this out the other day when one of our windows servers died because of a power out and a faulty UPS.

anyone used this one and can say experience:

Hello,

I'd like to clone existing CentOS server. Can anybody recommend any working solution to achieve that ?

It works great under the following conditions:

The target hardware is identical - or at least the same type disk controller.

The target drive is at least as large as the source.

You don't have software raid or LVM spanning drives.

Hm... Using Xen or OpenVZ it is similarly easy to clone a maschine, even without having to shut down things. However, I have the feeling that the thread starter has a physical machine to clone? ;)
