… long, long ago I recall reading that ZEVO can automatically reduce the priority given to a scrub, if it's sensed that initial priority makes performance of the Mac too poor for the end user. And I'm almost certain that I have felt the benefits of those reductions in priority.
Can anyone recall that documentation or discussion? With keywords such as scrub and verify I have searched without success:
- the quick start guide
- the ZEVO home page
- the wiki
- this forum
- local archives of private stuff from beta testing
– not finding what I want is a puzzle.
Maybe the automation is not specific to ZEVO, although ZFS discussions such as How to manage scrub priority or defer scrub? (2010-03) make me doubt that.
