Attached RAID, I must have misconfigured something.

    I have an O200, running 6.5.22f. I have a SCSI RAID array attached,
    that's been upgraded, by replacing the drives in the array, now
    there's 12x250 gigs. I was told that there's a 2TB limit on a SCSI
    file system, so I've divided the array in 2(6 drives each, RAID 5).
    I'm not sure, but somewhere I must have something configured wrong. It
    seems like when I use both drives I get a lot of problems, which makes
    me think it's related to luns or something. I am getting a lot of xfs
    errors:

    Feb 1 02:59:14 1A:oliver unix: ALERT: xfs_stack_trace[0]
    0xc0000000003061d0
    Feb 1 02:59:14 1A:oliver unix: ALERT: xfs_da_do_buf: bno 8388608

    /xfs_da_btree.c. Caller 0xc000000000328480

    I have 2 luns mapped. Now this seems wrong to me, when I fire up fx
    and I seem to succesfully see drives on

    dksc(6,1,0)
    dksc(6,1,1)
    dksc(6,2,0)
    dksc(6,2,1)

    hinv comes back with:
