Actually, it did identify it initially. ada0 was the offending 4096k 
sector drive. I replaced it, with a 512/512 sector drive, but the error 
didnt go away.

The drives in the set are all now 512

             ada11   ONLINE       0     0     0  block size: 512B

             ada9    ONLINE       0     0     0



# camcontrol identify ada11 | grep "sector.*physical"
sector size           logical 512, physical 512, offset 0
# camcontrol identify ada1 | grep "sector.*physical"
sector size           logical 512, physical 512, offset 0
# camcontrol identify ada8 | grep "sector.*physical"
sector size           logical 512, physical 512, offset 0
# camcontrol identify ada9 | grep "sector.*physical"
sector size           logical 512, physical 512, offset 0
