Raid-0 hw or software (a bit OT)
I have a computer with nvidia chipset that offers sata-raid. I have configured it with raid-0 (mirror) on two drives. BUT when I tested this setup by unplugging one drive (expecting it to go "oh! a drive is missing, oh well log a warning, and boot from the remaining mirror"). However this did not happen, the computer did not boot. So first off, does anyone have any experience with nvidia raid? Is there some way to ensure the system boots even if not all the drives in the raid is available.
Second. I am now considering setting up software raid instead, mirroring two identical drives. Would sw raid handle one drive unplugged? I have never really used sw raid in this context before. What I am after is security for my files. I am of course backing them up to a different media, but I want the convenience of hard drive access as well. The computer has two harddrives, so the system (mandriva 2008) would have to be on the raid drives as well.
