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
raidz1-1 ONLINE 0 0 0
ada11 ONLINE 0 0 0 block size: 512B
configured, 4096B native
ada1 ONLINE 0 0 0
ada8 ONLINE 0 0 0
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
