Hello everybody,

here is my problem: I have a computer which will be used as a router, firewall and fileserver. It has 2*40 GB hard-drives. I already installed Slackware 9.1 on the first disk and I want to mirror the disks, so I can sleep better at night
I have to mention I never did that before, so for the begining I started to read some docs and howtos. After I understood (a little) what RAID is and how it is done, I want to try by myself.
Is it possible to mirror the entire hard-disk (/hda) on /hdc without losing data? I have 4 partitions (swap, /, /home and /usr/local) and I would like to mirror all of them and change partition type to 0xfd (for autodetection). Is it possible? Or I have to reinstall? And how do I do it in each case?

I think I was not very clear, so if you don't understand my needs please ask for further explanation.

Thanks,
Ivan
