We tried dd but it kept crashing and I had to reboot, I forget the error but
tried it twice and both times the system locked up and required rebooting.
Any ideas on this.
Using dd what commands would you recommend ?
I have hda1 (primary) and hdb1 (secondary)
Could you let me know the exact commands to use dd ?
Maybe we are trying to send too much at one time, thesse are both 40GB hard
drive. Redhat 7.1
Thanks for any help.

You probably want to use 'dd' rather than 'rsync' for something like this.
It'll be much easier.

trying to clone to the secondary slave drive and be take the primary out and
change the slave to primary and boot from it. The problem I am having is
that it the copied drive will not boot, It is not getting the lilo boot and
config properly. When I try to boot the copied drive , it boots to a Blank
screen with an "L" in the upper left hand corner.
