That didnt help. I figured out whats causing the disks to never spin down. They werent also not showing any smart values. The hba lsi 9300 16i card was not updated to the newest bios and firmware. It was also very slow starting. Nearly 3 minutes took a reboot because of this hba. I I updated everything on this card like mentioned in this post HOW TO UPGRADE AN LSI HBA FIRMWARE USING UNRAID and now its working very fine. Thank you all for the help anyway! It really helped me understanding whats going on!

Yes it did before. What do you mean with "new Unraid install" ?

They dont. They try to spin down once and immediately spin up again. Every try after that will result in nothing till I reboot the system.

Could please somebody help me here. The disks arent spinning down and the summer is coming. They were above 50c last summer during parity check and i dont want them to be that hot all the time and to save some energy on them

Tried it, didnt work. I cant figure out whats preventing the spin down. Here are my diagnistics again. I hope somebody could help me out here...it worked just fine before 2 of my disks had corrupted filesystems. homepod-diagnostics-20230506-1258.zip

I cant find anything that prevents the disks from spinning down. They stayed on all the night wihthout docker or vm even activated in settings

Did that, pressed the "spin down" button for all disks and the hdds didnt spin down. All cache drives are spun down. Active streams doesnt show any activity and open files just has one process named "find" that is up and shows some paths in the cache.

Did the check, found some errors and did the repair as mentioned in these instructions. Now the array seems fine filesystem wise. But the disks wont spin down when not in use. How do i figure that out? homepod-diagnostics-20230503-2150.zip

Also my last parity check finished like that: Last check completed on Mon 01 May 2023 06:41:51 PM CEST (yesterday) Duration: 18 hours, 47 minutes, 18 seconds. Average speed: 147.9 MB/s Finding 45224462 errors

Thank you for all your support. I got the array working again but now i have a new problem or many. Fox Common Problems says "Unable to write to disk2". My mover does nothing I can see. All my disks arent spinning down anytime and my disk setting is set to a 15 minute spin down delay. I would really like to find the problem myself, so i dont need to relate to others to solve my problem, but i dont really know how. homepod-diagnostics-20230502-1904.zip

I think I understood that, but unfortunately disk2 is already empty and so is disk3. Only Data remaining is on parity1 but its disabled and I dont know how to bring it back. Is there a way to repair the parity or check it now in this config?

Since Disk 2 is empty because UnRaid already wanted me to format the disk every time it rebootet in order to be mountable, does that mean I could try to do a new config in order to get the data that is on the parity disk to work again?

The PSU was swapped out to a new one with more power now. I have a new controller but no cables atm, need to order them. Is it posible to get rid of the disabled mark on these two disks?

Its been a time, but I now had time to try it with new replaced cables. Now there is something else that seem wrong. The array just starts fine, but the perity with earlier read errors is now disabled and one of the formatted disks too. The other of the two formatted array disks shows up with no data but the array says its fine. homepod-diagnostics-20230413-1646.zip

The rebuild stopped at 0,0% now. Im afraid... diagnostics-20230408-1343.zip
