Sounds like you might need to use IPMITool to reset your values. Do you know what your lower threshold is for your fans? You’ll need to figure out how low you can run them and use IPMITool to set that in the BMC so it doesn’t freak out and ramp them up to full power. I set mine to correspond to my different fans in the system.

It makes total sense and I can’t believe I didn’t think about it. I don’t understand all the inner-workings of Unraid but I completely forgot I changed it from Auto to Reconstruct write when I was having to rebuild drives over and over again while tracking down the issue of drives intermittently throwing read and write errors. (It was a combination of things, an add on, software side and a 5 in 3 hot-swap cage where the backplane had something fail and had to be replaced)

Aka reconstruct write? Yes, I had that enabled instead of auto when I was troubleshooting my disk error issues. I think you’re spot-on, I just checked the logs and when the mover script ran overnight, it spun up the whole array when it moved a few items.

Just accessed the Windows Backup share manually to copy the files to a spinning HDD on the MCX1 system and it did NOT spin up the whole array. So, it's not anything to do with disk 9, it's something the process Windows Backup is doing when opening and modifying the files. I am at a loss, I'm just going to quit using unraid for Windows Backups. Nobody else seems to have an idea of what's going on, so F it.

I guess, at this point, if I want to keep all my drives from spinning up every hour, stop using unraid for my windows backup location. BTW, it's Windows 10.

I just tried opening another file on disk 9. It also stores my User shares (for Windows), Time Machine for my MacOS and a few other things and accessing a file manually by opening it via user share, it does NOT spin up the whole array. So it's SOMETHING Windows Backup is doing.

I just checked and disk 9 is on one of the standard SATA motherboard ports.

BTW, I appreciate your help. Can't seem to get anyone else to even look at it. I feel like I've narrowed it down considerably but just need someone that understands the innerworkings of Unraid more than I do. If it's a setting I need to check or change. I've tried everything, I tried changing the Windows Backup share (only on disk 9) to use the cache instead of writing to the array, I've managed to see a repeatable, maybe ancillary cause, when Windows Backup writes to disk 9. Other than when that happens, the array stays spun down. I can also demonstrate that when I have Kodi access a TV show, Movie or Song, it doesn't spin up the entire array, just the disk it's on.

I've tried disabling all plugins and dockers, no joy. I can spin the array down and it stays down until 30 past the hour when Windows Backup opens a file and modifies it on disk 9. As you can see referenced in the diagnostics attached. Windows Backup opens and modifies a file every hour at 30 past the hour. So I've seen what seems to cause the array to spin up and can predict when it happens. I just don't get why when only disk 9 and parity should spin up, the whole array spins up and has 5-10 reads, per disk. mrpunrfsx1-diagnostics-20240919-2010.zip

I uninstalled Fix Common Problems as part of my investigation. I did have that option checked (skip spun down disks) I just can't figure out why when Windows Backup accesses JUST disk 9 , it spins the whole array up.

I just wanted to add, I think this was a multi-faceted issue. I think there was an add-on that contributed to the intermittent write/read errors to disks. I ended up changing/upgrading every single component in my system. I changed the motherboard, processor (E3 to E5 Xeon), RAM (DDR3 to DDR4), drive SATA cables, LBA breakout cables, power supply (660W Seasonic to 850W Seasonic), power supply cables, PS cabling configuration and LBA card. Even after changing all that, I ended up with errors again on one disk and it couldn't be rebuilt, even in safe mode (like worked before). I just ordered a new 5 in 3 hot swap cage, I narrowed down the lion's-share of the issues to one 5 in 3 hot swap cage (an old iStarUSA cage) and am replacing that cage. I am OCD so I'll eventually change the other 3 cages (I have space for a total of 20 3.5" spinning HDD) but at 130.00 a pop, it's not cheap. I will say that I think the Silverstone 5 in 3 I chose is the nicest HDD cage I've used and I like that it's tray-less. this is the one I ended up going with:https://www.amazon.com/dp/B07ZWK1337?ref=ppx_yo2ov_dt_b_fed_asin_title

I changed the backup shares to use the cache_sdd then move to the array. We will see if that helps the spin-up issue. Thanks for all the help, BTW..

I just noticed a correlation, not sure why it's happening; hopefully someone can explain what's going on. Windows Backup is writing to a file on disk 9 at approximately 30 minutes past, every hour. It should be spinning Disk 9 and Parity up. Then within seconds, the entire array spins up corresponding to Windows Backup writing to Disk 9. Windows Backup only exists on Disk 9, by design. The share is only on Disk 9. Additional information: the share Windows Backup is set to not use the cache disk and write directly to the array.

I have no idea what is spinning the disks up. I tried disabling all plugins and dockers and something still spins them up every hour. I spun them down and can see when file activity (windows backup) accessed disk 9 but all the others spun up with something making a few reads to the entire array shortly afterward. I'd understand if disk 9 and Parity spun up but why did the entire damn array spin up? Maybe because I have a MacOS machine with Time Machine pointed to disk 9 also? mrpunrfsx1-diagnostics-20240919-1435.zip

It's a cheap one I got from Amazon Vine. We will see if it causes issues or not. I'm about to upgrade my router on the other side of my AT&T router to a Ubiquiti Cloud Gateway Max or Dream Machine. I haven't decided how much I want to allot for that purchase yet. I was looking at bifurcation on the new motherboard and can choose PCIE 1.0, 2.0 or 3.0 per slot in the BIOS.
