Cookbook way to set up raid1

I have a virgin system. I have two 9 Gig drives and Debian GNU/Linux. I want to create raid1 of /var and /home What's the best way to go about this? The software-RAID Howto is very _unclear_. brian -- Brian Lavender http://www.brie.com/brian/

make raid and retain data

temporary location, then restoring it to the /dev/md0 /home mount point later on. I succeeded at creating raid1 of /home with /dev/sda10 and /dev/sdb10, but I had to tar up all the data, create the raid, and then untar it all back onto the raid1 mount point? brian -- Brian Lavender http
