Got it. Fixed the ACPI issue. And yes, I've disabled the onboard raid. My issue appears to be with SAS disks not spinning down in unraid. I've found threads that it was a known bug in previous versions but can't tell if it was supposed to have been fixed. Either way, disabling spindown eliminated the error messages.

I seem to be up and running -- I'm currently copying my data over but my log is FULL of these messages (performance doesn't seem to be suffering too much but this can't be good!)

The umask issue was unrelated. Fixed that and still couldn't connect to the daemon. Rolled back to version 79 (I'm using the aarch64 builds) and it works again. I wish there was a way to flag a docker image as broken.

Recently my deluge instance quit connecting to the daemon. Log is here: https://pastebin.com/F16zrHF7 ./run umask is failing but I'm not sure what that means?

Haha I told you I was new to this! I thought the expander communicated to the controller via PCIe. Now that I've hooked it up to the HBA everything seems to be working correctly.

Borrowed an spp disk from a friend. It was 17.04 but seems to have updated some items. I also installed an HP SAS expander and 2x4tb drives. Unfortunately the drives didn't just automatically show up in UNRAID. How do I troubleshoot that?

Understood. I don't mind fan noise but it seems quite unnecessary at current levels. Obviously I can't obtain a SPP directly from HP but is there any risk in breaking something upgrading to another one that I can (hopefully) find?

Thanks to both of you. Very helpful info. @1812 I'll check out your thread. Any info you might have on quieting down fans would be appreciated. Mine aren't racing -- they come down about 50% after I boot -- but they do make more noise (and use more power) than I'd like. My usage on this box will be pretty low (it's replacing an Odroid C2 "server" that I've been running) so I don't see any reason to keep the jets fired up when it's mostly going to spend its days idling.

This is ALL new to me so excuse the dumb questions -- I'll be firing up UNRAID this week and want to make sure that my understanding of my hardware is correct. I purchased a DL380 G7 off of eBay. It's a 24bay sff unit. It showed up with a PCIe p410i RAID controller. The 24bay backplanes require 4x SAS cables. Two of these are connected to the PCIe card and 2 are connected to the mainboard. I also ordered a HP H220 HBA PCIe card. It's my understanding that I needed that to correctly use UNRAID in JBOD mode -- but there are only 2 ports on that card. Can I use some type of SAS splitter or do I need to buy an SAS expander? Either option is inexpensive I just want to make sure I have everything that I need to set myself up for success.
