Description

At present, zpool iostat output looks like this (from bdha)

               capacity     operations    bandwidth
pool        alloc   free   read  write   read  write

In the above, c0t7d0 is a log device

  pool: tank
 state: ONLINE
 scrub: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        tank        ONLINE       0     0     0
          mirror-0  ONLINE       0     0     0
            c0t2d0  ONLINE       0     0     0
            c0t3d0  ONLINE       0     0     0
          mirror-1  ONLINE       0     0     0
            c0t4d0  ONLINE       0     0     0
            c0t5d0  ONLINE       0     0     0
        logs
          c0t7d0    ONLINE       0     0     0
        cache
          c0t6d0    ONLINE       0     0     0

The iostat output should make it clear that c0t7d0 is a log device.
