Yay! FreeBSD is up and running, without any sort of RAID controller. After buying a 3Ware from eBay and having it need *identical* disks, I thought I was sunk. So, I ran out to Micro3000 (thanks, Erik!) and picked up a Promise FastTrak100 TX2. Turns out that this controller only does on-line swaps and rebuilds when using a special Windows driver. Gah! Oh, and manual, off-line rebuilds take forever. It took about an hour and a half to re-sync the mirror after I intentionally broke it. Ah well.
Anyway, to make a long story short, thanks to the wonderful help I received from
Oh, and yes, Erik, I think I will need to return that controller. It just doesn’t work quite how it says on the box. :\ Ah well. Things are good, for now.
