Dnk, I use two drives with linux raid 1 sets for the OS for all my CentOS machines, drives are cheaper than my rebuild time and hassle. I actually use 3 partitions mirrored on each: /boot of 100M; swap of 2 time RAM (disk is cheap); 70G as /, then the remainder is extended partition for lvm - in this case the extended partition is not mirrored as the contents are for mythTV recordings that I don't mind loosing. I have a HD TV card that takes 5G per hour of recording so space matters more than redundancy - also use xfs on this lvm part as it seems to work better for huge files. In your case I would set up both the raid 1 sets, put lvm volumes in place and allocate as needed for the mount points you want to have. Because you are using lvm, if you get the allocation wrong it can be remedied without too much hassle. Hope this helps.
