Well, if my RAID truly is dead and I can't recover any of the data on it (which it's looking like right now) then there's really no problem with me trashig that thing and letting ZFS take over. I have 8 disks in there. What I assumed RAID5 would do with that was 6+2, which is fine by me. If ZFS can give me the same result as a RAID5 array can (as in, a continuous 18TB filesystem with 6TB for parity, or whatever) I'm totally fine with that. I will have to read up on ZFS, which I should've done ages ago anyway.
