Timing of Periodic Mainteance Tasks on TrueNAS Scale (feddit.de)

EDIT: I found something looking through the source code on Github. I couldn't find anything at first, but then I searchedfor "periodic" and found something in middelwared/main.py.

Theses tasks (see below) are executed at system start and will be re-run after method._periodic.interval seconds. Looking at the log in var/log/middelwared.log I saw, that the intervall was 86400 seconds, exactly one day. So I'm assuming that the daily execution time is set at the last system start.

I've rebooted and will report back in a day. Maybe somebody can find the file to set it manually, not in source code. That is waaaay to advanced for me.

EDIT 2:

EDIT: I was correct, the tasks are executed 24hours later. This gives at least a crude way to change their execution time: restart the machine.

Hej everyone, in the past few weeks, I've been digging my hands into TrueNAS and have since setup a nice little NAS for all my backup needs. The drives spin down when not in use, as the instance only recieves/sends backup data once a day. Howevery, there are a few periodic tasks which wake my drives. Namely:

catalog.sync	                Success	26796 	12/03/2024 18:06:54 	12/03/2024 18:06:54 		
catalog.sync_all	        Success	26795 	12/03/2024 18:06:54 	12/03/2024 18:06:54 		
zfs.dataset.bulk_process	Success	26792 	12/03/2024 18:06:43 	12/03/2024 18:06:43 		
pool.dataset.sync_db_keys	Success	26791 	12/03/2024 18:06:42 	12/03/2024 18:06:43 		
certificate.renew_certs	        Success	26790 	12/03/2024 18:06:42 	12/03/2024 18:06:43 	
 
dscache.refresh	                Success	24991 	12/03/2024 03:30:01 	12/03/2024 03:30:01 
update.download	                Success	25027 	12/03/2024 03:46:01 	12/03/2024 03:46:02

I spend the last hour searching online and digging through files and checking cron. I found the dscache.refresh and the update.download. I can't find the first five. At least one of them wakes my drives. Does anyone have an idea? There used to a periodic.conf, but I can't find it on my system. Thanks!
