It treats the pool like any other device, so if there is even one outstanding request to the pool, it counts towards the busy%. Keith W. from Joyent explained this recently on the illumos-zfs list: http://www.listbox.com/member/archive/182191/2014/10/sort/time_rev/page/3/entry/18:93/20141017161955:F3E11AB2-563A-11E4-8EDC-D0C677981E2F/ The TL;DR is: if your pool has more than one disk in it, the pool-wide busy% is useless.
