Yep, I noticed this weekend it scrubbed saturday, sunday and monday back to back despite being set to 7 days. I set it to 14 days last night and it scrubbed again this morning.
I noticed the same exact issue all this week. Did a clean install after an schedule upgrade and every night at 345a there is a scrub on the boot pool. I have another scheduled upgrade tomorrow, which includes moving the boot pool to an NVME. I'll post back after reinstalling TrueNAS and loading the config file.
After our upgrades and a fresh install of 22.12.2, the issue persist. I tried searching open bug reports but didn't find any. I will submit a bug report today.
I just installed TrueNAS-SCALE-22.12.2 a couple of days ago. The scrub is set to 7 days but it is actually scrubbing every 6 hours. I don't know how to stop it!
