Since my HDD failure I'm trying to be more proactive. I've followed @cyberjock guide to Scrub and smart test schedules to make sure srubs and smart tests don't happen at the same time. My long tests take 527 minutes. Is it ok to have them run for all 6 drives at the same time? If they start at 4am they won't finish until ~1 PM. Can I still use my freenas while that is going on? I've included jpgs of my setup in case someone has some comments.
