Ive got two free spaces...whats up with that? The two at the bottom (sda and sdb) are the actual 250gb HDDs. If i didn't install the dmraid thing like the "how to" said to do then that would be all that shows up. Anyways, what do i do about the two free spaces and what is all the stuff in the middle supposed to be(dev/mapper/sw_ccjdedhaif_dark1 to "..."_dark9)?
