I have a 4 gig system disk that is 98% full.  I want to copy the entire contents to a larger 73gig drive.  The contents is irix and all my apps.

What is the best way to do this instead of reinstalling everything’s no from scratch.

insert second disk, "fx" it to be a root disk, run this script (as in save it, name it "clone", as root do "./clone 2" if your new disk will have scsi id of 2, then type 0 if its on scsi controller 0):

Code:

#!/bin/sh
# program to copy root & usr partitions and create a new bootable disk
# Note that this script is limited to SCSI drives, and only those
# on controller 2.
# It makes the root & usr filesystem on partition 0 & 6 for destination drive
# and install sash, ide & fx in the volume header of  the destination drive.

if [ $# -eq 0 ]
then
       echo "Usage $0 [disk_number]"
       exit 1
elif [ $1 -eq 1 ]
then
       echo "The disk number needs to be greater than 1."
       exit 1
elif [ $1 -le 1 ]
then
       echo "The disk number needs to be greater than 1."
       exit 1
else
       NUM=$1

Is this still the suggested method for disk cloning?

[callahan]

Yes. Xfsdump/xfsrestore is the way to go. It's not hard to do with a few basic commands (fx, mkfs, and xfsdump | xfsrestore), but I assume this script will work too.

[pcar]

This process worked perfectly, thanks all!

I cloned my hard disk to a SCSI2SD for my Indy without any problem. Now it works a little bit more silent.

Thanks!!!
