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?

I could never get the docker to work, so I'm still using the Phaze plugin that has worked for years.

I assure you that when I went into the Docker settings for the first time ever, those values were already filled in like that. To me, that's the same thing as a default setting. Can I just create the right settings/shares/whatever? Is there anything that I need to watch out for, or is it pretty safe to play around with this and try different things?

If you click on it, the screenshot should be crystal clear. I didn't specify anything, everything you see is what unRaid has by default. Everything I'm reading says I should use mnt/cache/something for Dockers. But I'm still not confident that I'm grasping the concepts right.

I definitely don't have an appdata share and I never deleted it. I've been using this unRaid server since before Dockers were an option, so maybe that's why it wasn't created by default? So, if you can see that image, you know what I have under Settings>Docker. I can't get past that screen without, I presume, creating appdata and Appshare. I was hoping someone could outlined what I need to do to not mess that up.

Should I just create an appdata share? And Appshare? How do I do that? It's not a regular user share, right? Sorry, I'm a total newb (experience-wise if not time-wise), but my Plex plugin just stopped working and I figure it's time to get this new Docker thing working. I tried reading through all of the pinned posts, but several of them are completely outdated, and I'm unsure how accurate some of the others are. I made it through the Space Invaders video, but, as you can see in this screenshot, I was quickly derailed and unable to simply do what he describes. I'm one of those guys that likes to get things going and then leaves it alone. I know a lot of you guys tweak your servers, but I can go months and months without ever looking at my unRaid settings.

Ah, well, that's good to know, too. I have not actually encountered it with unRAID. I was just thinking back that several years (yikes, a decade?) ago a "1 GB drive" might have different actual capacities depending on the make and model. I figured that now that I'm looking at 10 TB drives, that the issue might be just as common.

I didn't have notifications set up until I was updating software to prep for this parity drive upgrade. Now it emails me more than I would like. I don't tinker with it much. I know next to nothing about linux, so I had to read tutorials and follow them word for word to get this server set up and I don't want to do anything to make it not run! I check the server GUI every week or so to make sure the Plex plugin is up to date, but I don't do much beyond that. I'm thinking about adding the rclone plugin and using Backblaze B2 to back up my irreplaceable photos, so it looks like that may entail dabbling with text commands (which I absolutely hate).

Excellent. Good to know. Thank you for the response.

Hmm, I did what you said, and it didn't work to take me to that thread. But thanks for finding that thread for me!

So, I recently replaced my parity drive with a 10 TB drive and have decided that I'm saving up to buy another 10 TB drive to upgrade to dual parity when I get the chance. That made me think about what happens if the drives aren't exactly the same size. If I use two different brands of drives, and one is 10.1 TB and one is 10.2 TB, will unRAID still be able to use 10.1 TB of parity (and the extra .1 TB on the larger drive is just ignored)? Same question with a data drive, I guess. If I stay with single parity, and have a 10.1 TB parity drive, could I put a 10.2 TB data drive in my box and that last .1 TB is ignored? Or does the data drive absolutely have to be smaller than the parity drive?

I just wanted to thank everyone who helped me with this. My unRAID server is working like a charm. I've already replaced my smallest, fullest drive with my old 6TB parity drive and everything is running smooth. And I'm saving up for another 10TB drive so I can switch to dual parity in the future. I do have a question on that, but I'll start a new thread.

Anyone know how to translate this link to the new forums format?

Here's a screenshot of my MAIN tab:

OK, the parity rebuild is done and it's telling me parity is good. I'm starting a parity check now before I take it out of maintenance mode. One thing that didn't look right, was that it gave me an error where the Total Size should have been indicated: Warning: parse_ini_file(state/diskload.ini): failed to open stream: No such file or directory in /usr/local/emhttp/plugins/dynamix/include/DeviceList.php on line 21 10.0 TB Please tell me that I was right and that this isn't a dealbreaker.
