Installing to SATA fakeRAID

Hi All,

Here's the deal. I have an Abit AV8 3rd Eye motherboard and a pair of 300Gb SATA drives. I want to install a Linux distribution (preferably Red Hat Fedora) and put everything on one or more RAID 1 partitions from the start. Is this feasible? Or should I lower my expectations and install the O/S on a non-RAID partition and set up my RAID 1 paritions for data after the installation? The AV8 is a fakeRAID motherboard, which probably influences the options.

In any event, does anyone have experience of either installation scenarios, or links to installation guides that cover either of these?

It's generally not a good idea to install your OS on a RAID partition.. you *are* going for RAID1 (backup), so I suppose it may be worth doing. To do it, you have to be able to setup the RAID at or around BIOS time which requires a real RAID card or motherboard with RAID support and some method of defining the array.
Once the array is defined, you'll simply install the OS on the SCSI drive that more recent versions of Linux *may* see.

If I were you, I'd install the OS on a non-raid partition, setup the drives as individual, then use a software RAID in Linux to create your RAID (in which case, the type of mobo you have really makes no difference... though, in your case, that's not much of a concern being that it sounds like your mobo doesn't really do hardware RAID control anyway).
Doing it this way is pretty easy... there's plenty of documentation on it - look at fdisk and "Linux Software Raid" in google. If you want to be lazy, software raids can be setup easily with Webmin.

Of course, if you want performance, go out an buy a real hardware controlled RAID card from 3Ware. Stay away from Promise.
