I'm looking at getting a new box and wondering what people's experiences are with mirroring via ataraid(4) and various motherboards. Does it work? Does it tell you when a drive fails? Does it do the right thing when you put in a replacement? Does it work if the two drives aren't identical? Is performance acceptable? At the moment I'm using gmirror (previously ccd until GEOM came along and ccd became unstable) with a dedicated unmirrored OS disk. But in accordance with Murphy's law, I've had the boot disk fail twice in the past five years, so I'd like to put the damn root fs on the mirror.
