I don't know of any way to observe IOPS per zvol and I believe
this would be tricky. Any writes/reads from individual datasets (filesystems
and zvols) will go through the pipeline and can fan out to multiple
mirrors or raidz or be striped across devices. Block writes will be
combined and pushed
Brendan Gregg has put together a few dtrace scripts for looking at
various parts of the zfs subsystems recently. I don't find them in
the DTraceToolkit-0.99 release though.

If there a simple, existing way I can observe the read / write / IOPS on
a per-zvol basis?
If not, is there interest in having one?
Cheers!
