FreeNAS: How to increase scrub 'threshold'?

My NAS box is set to default scrub threshold every 35 days. How do I change it to scrub every Saturday night? Do I need to create a cron job? I'm on FreeNAS-8.0.4-RELEASE-p2-x64 (11367)

setting up expandable raidz

I heard you can expand a raidz if you add one with the exact same setting. So is it true that I can build a raid-2z now using 4 disks (so I have 2+2) and later on add another 4 disks so I have a raid-2z with 6+2? Or will this lead to 4+4? Is it even…
