Problem/Justification I want to spin down disks over night / long periods of inactivity to save power. Energy is really expensive here in Europe, thus saving power over night / weekends is desirable. The toggle for HDD standby is already available in Truenas Scale, however, it no longer functions …

@Jaywalker Have you generated any scripts that would perform this function and then make a CRON Job for running the scripts? I ask since it “should” be fairly simple to do. You will find out that the main problems are going to be and drive activity would pull them out of the deep sleep and they “…

Possible patch: [image] HDD Sleep/Spindown/Standby TrueNAS General For those like me who finds TrueNAS the better choice, just wish it could do spindown properly for home usage, and are willing to tinker with it, here is a patch file of the changes I did to get…

Just a thought. You could perhaps schedule shutdown (maybe a chron job) change bios to start at power failure have a smart switch that can shut down / power up on schedule. My expectation is that TN will stop gracefully The smart switch cuts power completely a bit later Smart switch turns on po…

This approach is not feasible for many home lab users. Many opt for an all-in-one solution to reduce costs, meaning the gateway might be located on the TrueNAS, and the network would be interrupted when the system is shut down. Even without considering whether the gateway is running on TrueNAS, man…

The above two post are going off-topic: This is a feature to spin down drives with the NAS on, not to shut down the NAS. Thank you for reading. [image] Apple: the gateway might be located on the TrueNAS This is generally advised against anyway: Keep your basic network infrastructure independ…

The original post is about the benefit of spinning down the disks to save energy. I am still on 24.04 and considered the feature (but I am not using it) spinning down wears out the disks enormously. From what I was able to find - disks are rated to about 150000 start ups. This may seems a lot but …

I fail to comprehend why people are so indecisive. It’s a simple toggle switch that doesn’t function properly. If it did, you could easily toggle it to your desired setting, either keeping it spinning indefinitely or turning it off. Are you concerned about the hard drive exploding if it spins down…

[image] vbs: spinning down wears out the disks enormously Any data to support the word “enormously”? 365 days per year. 3 times that is a little over 1000, so back-of-the-envelop calculation goes that 150k spin-ups amount to 3 spin-ups a day for 150 years, or 30 spin-ups a day (over one per …

[image] etorix: Any data to support the word “enormously”? I guess this comes down to drive brand and actual number of spins. Some can handle more others less. No point to quote AI here but each person who is interested can do their own research. At the end - it is a big deal for some and not…
