It seems you already have the Unassigned Devices plugin, and you're able to install it now. The button is showing in your screenshot. It took me forever (or maybe just a few hours) to figure out that the prerequisite of having "Uninstalled Devices Installed" meant another plugin and not that I had uninstalled devices in my server. It's not clear at all and a couple of extra words would eliminate that confusion.

Thanks. I thought maybe if I rebuilt both, it would be the same as rebuilding single parity in terms of protection, but thinking about it further, I see that dual parity is completely different from single parity. I've actually decided to stick with single parity until I'm done reformatting my ReiserFS drives. I think having a much larger data drive will make that a lot easier. Thank you again!

Hmmm... Forgive me as I'm slow sometimes. How would that apply to my situation? I don't really want to touch the data drives until after I've upgraded my parity drive(s). I was just wondering if I had to upgrade my existing single parity drive first, and then add the second parity drive, or if I could rebuild both at the same time. After I've upgraded my parity, I do plan on replacing a data drive with the old parity, and then trying to reformat the disks that are still ReiserFS when I'm able to figure that out. But parity first before I touch any data disks.

OK, so I bought a couple of 18TB drives, and I was going to use one of them to upgrade my parity disk and the other to upgrade a data disk, but after a recent scare where I had two missing disks (turns out it was a known issue with WD drives and SATA power - both drives are fine), I think I want to move to dual parity. I searched the forums and wasn't able to find anything on this. Probably because I suck at searching. Should I replace the single parity and let it rebuild first, or is it possible (and safe) to throw both drives in there at the same time and rebuild them both at the same time?

That was the problem. Got a molex-sata power adapter and the drives are there now. Thank you very much!

Huh. I guess I'll try a molex to sata adapter. Amazon will deliver that in a couple of days for under $5, so it's a cheap and easy thing to try.

It's an internal enclosure (fits in where 4 drive bays are in my case, and allows 5 drives to fit in the same space). The old cage had a backplane that split the power for the drives and connected the data cables to hot swap bays, but I've replaced that with an enclosure that uses direct cabling. So it's not the enclosure. And I've swapped out cables (both data and power) and the cables work fine on the other drives. The problem stays with the drives, which leads me to believe that it's not an issue with cables or the power supply.

I'm not sure if it's a coincidence or not, but I upgraded my router (which is physically near my Unraid server box), and shortly after, I had two disks go missing. I figured maybe I jostled the server, so I shut it down, and checked the cables. They seemed solidly connected. Then I assumed it was the drive enclosure (it passes data and power through the enclosure) that both of the missing drives were in. New enclosure has cables going directly to the drives. Same two drives are missing. So I bought a SATA card to try. Same two drives missing. Switching out cables and SATA ports shows that it's a problem with those two hard drives. I thought I had the server set up to send me notices if there were SMART errors. It certainly let me know when I was getting low on disk space. What are my options now? Seems odd that two drives would fail at the same time with no errors leading up to their failure. This has certainly cemented my decision to add a second parity drive, but I'm hopeful that there's something I'm missing that is obvious to one of you.

I'm having the exact same issue.

Oh, wow. That was easy. It seems that all my preps were unnecessary. Once I swapped the CPU, there wasn't anything else I had to do. It just worked. Nice.

This thread was exactly what I needed. I built my unRaid box on a Z87 Mobo with an i3 CPU and it seems to be maxing out the CPU more and more often lately. So, I can just throw an i7 (the older ones for my mobo are fairly cheap now and that should be more than enough processing power) in there and there's not much of anything that I should have to do with unRaid, right? I'll screenshot my "main" screen with all the drive assignments just in case. Anything else I should do before I swap out the CPU? I haven't done anything to set up any VMs. I just use dockers (Plex and Zoneminder NVR) and an older Phaze plugin for Transmission (I tried switching to Docker, but couldn't get it to work). None of those things should care about the CPU changing?
