I woke up this morning to this error on disk 5. I have recently started running PlexCache which I assume may have been giving the disks a workout. Should I replace the drive or is it likely a cable issue? Diagnostics attached. tower-diagnostics-20240831-0824.zip

Rebuild has completed successfully. A reboot has fixed the Array Operations tab too. Maybe it’s time for an update. thanks again for your help!

It’s happening with Safari too. Not to worry. It’s 75% of the way through the rebuild so we’re looking good. Thanks for your help @JorgeB!

yeah, I've done that now and it's rebuilding. The Array operaions tab has only 3 buttons and the main tab still has dropdowns, even though it's doing a rebuild. Is that as expected?

OK, I stopped, restarted with P2 unselected, stopped again, reslected P2 and started. It was rebuilding parity this morning, but I just checked it and it has write errors in the logs, and it says it's paused at 1.7% of a parity check. In the Array Operations tab I only have reboot, shutdown and sleep. Whast my best course of action here? Can I reboot, and then deselct P2? Will it need to rebuild parity on P1? I'd be happy with single parity for now if it gets me up and running. tower-diagnostics-20231123-1420.zip

A few months ago I swapped my SATA cards for a HBA as I had been getting UDMA CRC errors. Everyting has been fine since, but I had to shutdown the server today for the first time and on restart, one of my parity drives is disabled. SMART looks OK to me (but I'm not an expert). Is there anything to be concerned about here? Do I just need to rebuidl parity? tower-diagnostics-20231120-1107.zip

You should exclude your cache drive in the plugin settings. 47deg is usually fine for an SSD. Mine ran constantly when I got new SSD's until I excluded my cache pool.

FWIW, my KP issues were down to BIOS version. I updated to the latest Gigabyte BIOS and it ran fine for the past 3 years.

I thought I might post this here as it's taken me a while to piece it all together and it may help someone else get Fan Auto Control working. I have a Gigabute Z390 Aorus Elite board. Unraid can't support the fan PWM controler out of the box. I spent a couple of evenigns playing with sensors-detect btu noting was recognised. Then I found this page: https://github.com/a1wong/it87/issues/1 Essentially, you go to Main -> Boot Devices ->Flash -> Syslinux Configuration -> Unraid OS Change the second line from: append initrd=/bzroot to: append initrd=/bzroot acpi_enforce_resources=lax Then add this line to your /boot/config/go file: modprobe it87 force_id=0x8628 Reboot and Fan Auto Control should see your PWM fan.

I’m fairly sure you need to edit settings.json. Not sure which one though. Possibly the one on the flash drive.

As luck would have it, today is my 6th anniversary - at least it was 6 years ago I received my licence key. While I’ve had a couple of issues over the years, they have been few and far between and almost always been answered quickly in the forum. And I’ve not lost a byte of data in that time! I come for the parity, but I stay for the community!

I’ve had some success with the resilio sync docker as a replacement.

The Open Files plugin will show you which processes have open files. I found this very useful to track down why my disks were spinning up.

Do you have any unassigned drives? It looks like they are monitored but there is no way to exclude them. I had this issue and disconnecting an unassigned drive fixed it.
