zfs discuss - Apr 2006 - ZFS iostat question

Howdy,

While playing around with ZFS, I came across the following zfs iostat 
output:

$ zpool iostat -v 5

                capacity     operations    bandwidth
pool         used  avail   read  write   read  write
----------  -----  -----  -----  -----  -----  -----
snaptest    9.87G  40.6G      0    200      0  25.1M
   raidz     9.87G  40.6G      0    200      0  25.1M
     c1t1d0      -      -      0    100      0  12.5M
     c1t2d0      -      -      0     85      0  10.6M
     c1t3d0      -      -      0     78      0  9.82M
----------  -----  -----  -----  -----  -----  -----

Is there a reason that the number of writes to c1t1d0, c1t2d0 and
c1t3d0 don''t roughly equal the total number of writes to snaptest?

Thanks for any insight,
- Ryan
