My guess is that wd0 is a 512e disk (4k physical sectors, but emulates 512byte/sector) and that isn't handled consistently. Apparently the vdev code uses the physical sector size and the zvol code uses the logical sector size. Can you please verify that wd0 is such a disk ?
I guess this is one of these disks: [ 4.598545] wd0 at atabus1 drive 0 [ 4.598545] wd0: <WDC >[ 4.598545] wd0: drive supports 16-sector PIO transfers, LBA48 addressing [ 4.598545] wd0: 1863 GB, 3876021 cyl, 16 head, 63 sec, 512 bytes/sect x 3907029168 sectors
(4096 bytes/physsect; first aligned sector: 8)
