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?)

Thanks very much,
Eric Parusel
