That PSU tester (I have the exact same one) only tests at idle current, it does not put any load on the supply. Similar to the memtest, it only can confirm a failure with a negative result, a pass by either memtest or that style of PSU tester just means it passed under certain conditions, not all conditions.

Screenshot in first post shows no parity. Would building parity after the fact work?

You will need to add a mapping with host side having the Unraid path, and the container side set to whatever folder you want to point deluge to. Docker containers can only access mapped paths, they have no way to get out of their own sandbox otherwise.

Put a whitelist rule in your firewall and only allow known IP's to traverse the firewall.

Looks like that one has 2 internal ports, the entire purpose of this thread is breaking out drives into a separate tower. I assume if you don't want to use 2ea external to internal adapters with the appropriate external cables it would be better to have at least 1 external SAS connector. Perhaps the local prices make it more advantageous to use internal -> external -> external -> internal with 2 sets of internal cables, 2 internal external slot adapters, and 1 external cable?

No, because I am not experienced with virtualizing Unraid. All my experience is bare metal. I don't understand why you would want to pass multiple small virtual disks, I assume (perhaps wrongly) that your actual disks are much larger, and you are just carving off small bits to pass through. Performance is likely to be terrible.

Probably because it's the only storage drive available to Unraid for the docker and virtual machine image files. I'm assuming you enabled the docker system with default settings, creating a 20GB virtual disk image file to store the downloaded container layers.

That one only has internal connections, so would need ANOTHER adapter to use external cables. If you have plenty of empty slots in your main tower, that might be an option. The HP Proliant H222 Host Bus Adapter listed I believe might work, but I don't know which cable to use and which adapter on the disk tower side. @JorgeB?

Post a link. The only result a google search for that part number came back to an 8i version. The ASM are SATA, not SAS. To work with an SAS expander you must get an SAS controller. That's why I said look for LSI. I didn't mention ASM, they won't work. Intel RES2SV240

Unassigned Devices plugin

Port mappings only apply if the container is bridged to the host's (Unraid) IP address. Since you assigned a specific IP to the container, all ports are open on that IP, so any changes need to be made in the container app config.

After using both, I prefer tmux. I believe either is available in nerdtools. https://www.howtogeek.com/671422/how-to-use-tmux-on-linux-and-why-its-better-than-screen/

Since there are so many different options for preclear, it's difficult to know for sure what's going on. Please post in the specific support thread for the preclear that you are using. Possibly this one?

Not sure where you got that. It will rebuild parity to the drives assigned to the parity slots. You can remove or add whatever drives you want, parity will be built based on the data drives included.

tools, new config, save all, main gui page, unassign drives you want to remove, start array to rebuild parity without them. Do NOT select parity is already valid, it is not, it must be rebuilt.

Docker run commands for each of the containers, be sure to redact any credentials.

Floating grounds are bad, mkay? Plug the UPS into a switched outlet or power strip, then turn off the power to it without breaking the ground connection. Chances are high you will get away with just yanking the cord, but the possibility is definitely there to create a very large voltage differential across cords still plugged in to the UPS, for example the USB lead. This could blow out the USB port. Many years ago I personally fried a surge protector plugged into a UPS output when I yanked the supply out of the wall to demonstrate how good my UPS was. Rather embarrassing, but I was really glad the only damage was the surge protector, not the connected equipment.

Formatted is NOT blank, it has an empty filesystem with all the table of contents and file metadata structures ready to accept files. Parity doesn't have any concept of files, or any format for that matter. Moving files around on array disks doesn't invalidate parity as long as the array is started.
