To add my 2 cents, I use pqdi (PowerQuest Drive Image) to do this, as well as storing image files elsewhere for disaster recovery purposes. The only thing with it is that it doesn't get the MBR, so I have to run lilo after a drive restore on a blank HD. (I boot to a floppy or CDROM on RHL to do this) I had problems somewhat similar to "linux freaking out b/c the drives were different than it thought" when I was trying to get RAID-1's working in RHL6.0. I would get the mirror setup, but if it broke and I rebooted with the still good drive on a different point in the IDE chain (ie, it would show up as hdc instead of hda b/c I moved it) bad things happened; it would scream that the drive formerly hda was now hdc and fail to boot. Granted, my raid was pretty badly hacked at that point, because I couldn't quite get boot raid working right, so I was raiding some things and not others. It was ugly. In any case, I ended thinking there was either some information in the MBR or in an /etc file somewhere that was storing information about location of drives. Since the drives were now in a different location or in your case different machine, even on machines of identical hardware, that stored information was wrong. Can anyone shed some insight on whether I'm completely off my rocker here? For me, the problem got solved with RH6.2, which handles boot raids much better. Unfortunately, that doesn't help your situation. Sorry :P. Good luck, Brian ----------------------------- Brian J.

Plug the blank drive in as hdb on the system you've got running. Format it. Then, cat /dev/hda > /dev/hdb. Of course, "this might take awhile".... then pop it in your new machine and it should behave exactly as the original system. -Sally ----- Original Message ----- From: "Katz" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, October 25, 2000 1:57 PM Subject: [techtalk] linux mirroring > Hi, > I have 2 computers exactly the same in hardware. > After I installed linux RH6.1 with update kernel 2.2.14, > I used GHOST dos program to create a mirror on a dos > partition.
