Thanks for the heads up...
This is a clone pool, and the original is still intact after I recycle
these volumes.
Thanks!

Joel,
Be careful with the "brute force" recycling/relabel operation.
You MIGHT get yourself into a situation that you recycle/relabel volumes
with saveset needed for recoveries within the last 30 days...
Also be careful with volaccess - it is the last time the volume was
accessed, for read or write. So even just mount will count.
