Ghosting Red Hat 4
Hey all,

I'm trying create a red hat 4 image, and the first time around, i ran into the issue saying it couldn't read the drive or what not, but I found out that I had to use the -IA switch when using ghost.

Here's the kicker, I use the -IA switch and it does a sector by sector read, so that mean it'll use up 80GB of storage to storage the image...I just want to know what kind of switch I need to use to create a standard ghost image that isn't 80 GB

Whether you use Ghost or more down to the earth use the dd command from a Linux you can only clone a partition or the entire hard disk.

If your source Red Hat has several partitions you can clone them one by one and it wont take up the entire hard disk.

Remeber Linux identifies the hard disks by the connection points as hda, hdb, hdc and hdd for IDE cables and sda and sdb for Sata. You must use the target disk in the same hardware connection point for the Linux to boot properly.

It may come as a surprise but using the dd command in terminal mode is the best way. Say your Red Hat have 4 partitions hda1, hda2, hda3 and hda4. All you need to do is to use cfdisk program to create hdb1, hdb2, hdb3 and hdb4 identical to the size to the first lot. These 4 lines Bash commands will clone the lot
Code:
dd if=/dev/hda1 of=/dev/hdb1
dd if=/dev/hda2 of=/dev/hdb2
dd if=/dev/hda3 of=/dev/hdb3
dd if=/dev/hda4 of=/dev/hdb4
