Thanks for the reply's, I'm assuming to do the repartitioning with fdisk
or gparted to repartition, what tools do I use to manage the software
raid? I.e. how do I go about changing the swap partition to raid1 and
re-add the partitions to the array? This system is for me to practice on
for my RHCT/E exams(too broke to pay for training) so I'm planning on
breaking one of the drives(just remove it) and add a new one for
practice.
Thanks in advance,
Stephen
