Hello,
running Truenas at home where I have a Pool of 8 spinning disks for cold storage. Have an SSD pool for stuff I access regulary.
Due to energy prices in Sweden this not so fantastic year(and perhaps years to come) I want the disks in standby and not spin them up unnecesarily.

I have a fresh installation of Truenas Core 13, no jailed services running, boot-pool is on a single ssd.

However something spins up the disks two times between 02:00 and 04:00 every night but can't figure out what. It's just two read operations for a few kB.
Scrub has default to run once a month and currently I have not configured any smartd checks in the web ui.

So wonder if anyone got any idea on what could be spining up the disks?
