I have just about completed a setup for a RedHat 6.2 workstation with
all updates and a bunch of customizations to it. I will need to
duplicate this on a bunch of new machines with identical harddrives.
What is the fastest way to duplicate these multi partitioned drives? I
experimented with dd about 6 months ago but it seemed really slow.
What I am going to try is booting from toms boot disk with both the
newly configured drive in it and a new emtpy one. Then do dd if=/devhda
of=/dev/hdb
Would I gain anything by putting the empty drive on the second
controller (/dev/hdc)?
What would be an efficient block size to use?
Will this setup lilo (on the mbr) as well?
Would I be better off just cpioing each partition to a server and
creating a script that will partition the new drive, copy the files,
mount the new partitions and run lilo? I guess this would not lock me
into a specific harddrive geometery.
There is some significant emtpy space on some of these partitions as
well as some unpartitioned space at the end for future use. These are
10GB drives with about 40% unpartitioned.
I guess I could fdisk the partitions and then dd the individual
partitions? Is there a way to copy or script non interactively the
creation of partitions on a hard drive?
I have never actually tried to use cpio or cp for that matter to create
a real installation. I have always backed up stuff but have never
really had to recover one yet execpt for my testing and there I did a
new install and just copied my data over.
If all goes well I will be needing to replicate this installation a lot,
so any tips on how to set this up are greatly appreciated.
Thanks,
Bret
