Well you shouldn't be seeing one ~250GB drive if you have 3 250GB drives
in a RAID 5 configuration.  You _should_ see on drive with about ~500GB
on it as 1/3 of the total drive space is used for parity across all 3
drives.

So what I'm saying is, I don't have a clue why you're showing ~900GB
when even with those 3 drives striped you should only see ~750GB.
