Mind if I squeak in one little comment on the state of hardware RAID card support...? I wish I could back it up with come code, but I'm just a lowly sysadmin :) (maybe one day, in one way or another) While as far as I can tell RAID card support is quite stable (knock on wood, thanks guys and girls), there's a noticable absence of RAID array control & status reporting software for many types of RAID cards, including my own (NetRAID 3i, amrd driver). For instance, for my particular type of RAID controller I cannot tell if the array has degraded without walking up to the server and seeing amber warning lights.... :( Good thing I'm not using these cards in a colo :) Even a simple syslog message saying "Houston, we have a problem" would be invaluable.. :) Of course I'm definitely not expecting the world, just though I'd point this out :) By the way I'm using either RELENG_4_5 or -stable on my boxes... Oh, and a question: can software RAID mirrors (via vinum) be booted from? (and still booted from if one drive goes down?)
