In case of people run into the encryption issue: One problem was that the keyfile I was using was too large. I'm not sure what is the maximum size but 8.2MB was too large. Also to format and encrypt a new drive I needed to place the keyfile manually at /root/keyfile, the contents of the /root directory is in ram so it gets deleted when the machine is shut off or rebooted.

Oh I just went back and yes you are right sde isn't cache1 but my unassigned parity1. I just wiped it and I don't have any more errors except for one in syslog. My array started automatically when rebooting and didn't ask me for the keyfile. Feb 9 20:57:53 Tower emhttpd: /mnt/disk2 mount error: Volume not encrypted I will do more research on that. Sorry about that. I wasn't very vigilant. Thank you so much @johnnie.black

Looking at it again it looks like my disk1 (sdd) and cache1 (sde) both have the same UUID even though they have been running together for a long time. Is that possible?

Thank you so much johnnie.black! That fixed it! Is this in the documentations somewhere cause that really got me? On a side note, I have been providing a keyfile (a photograph) on array start but disk2 states "Unmountable: Volume not encrypted". Unraid gave the format option but that didn't change anything. Something doesn't look quite right. Feb 9 20:08:23 Tower root: Starting diskload Feb 9 20:08:23 Tower emhttpd: Mounting disks...

Sure I will get that sorted and post back. Thank you so much for your help! All of the disks have been in the system for many months now. sde is actually my parity1 drive that I moved off of the array after running New Config so that I can move data faster with unBalance so that I can encrypt disk1. The only drive that changed was parity2 which is being moved and formatted as btrfs encrypted. When the array started with disk2 unraid asked me to format it so I did. Then upon restarting the array is when I got the cache drive problem. I didn't know if UUIDs ever change in hard drives but there are supposed to be so many that its basically impossible to duplicated them. What are the chances? 🤣

disk1 is full of data and disk2 was in the process of being changed from parity2 to disk2 so its empty. Its does look like Unraid thinks that they were in the cache pool before and now they are not. I think I stumbled on a bug here. If I mount the problem cache drive as read only in unassigned devices all the files are there.

Unfortunately I rebooted since this happened but here is what I've got right now. Is there a log history? I also posted something in the first post. This is the line that I don't get. I only ever had these same two cache drives. Feb 9 16:18:38 Tower emhttpd: cache NumMisplaced: 3 syslog.txt

Hey guy's, long time Unraid user here. I ran into something that doesn't make sense. I haven't added or removed any drives in a very long time. Cache 1 states "too many missing/misplaced devices" and wants to be formatted even though it's file system still states btrfs. Feb 9 16:18:38 Tower emhttpd: cache uuid: 0b1c567a-f0dc-4b7e-a313-8d098ed56c16 Feb 9 16:18:38 Tower emhttpd: cache TotDevices: 2 Feb 9 16:18:38 Tower emhttpd: cache NumDevices: 2 Feb 9 16:18:38 Tower emhttpd: cache NumFound: 2 Feb 9 16:18:38 Tower emhttpd: cache NumMissing: 0 Feb 9 16:18:38 Tower emhttpd: cache NumMisplaced: 3 Feb 9 16:18:38 Tower emhttpd: cache NumExtra: 0 Feb 9 16:18:38 Tower emhttpd: cache LuksState: 0 Feb 9 16:18:38 Tower emhttpd: /mnt/cache mount error: Too many missing/misplaced devices Feb 9 16:18:38 Tower emhttpd: shcmd (1310): umount /mnt/cache Feb 9 16:18:38 Tower root: umount: /mnt/cache: not mounted.

Two as parity and one as data. I needed more space and wanted to encrypt my data so I decided to move my parity 2 drive as a data drive. I stopped the array. Went to new config and chose to preserve cache assignments and clicked apply. I changed the default disk format from btrfs to btrfs encrypted. Then I reassigned my parity 1 and disk 1 the way it was before and added the old parity 2 drive to disk 2. Of course my cache drives are still in their respective places. So then I chose a keyfile and clicked on start array. The disk 2 didn't have a file system and required a format so I went to the bottom of the main page and saw the option to format disk 2. No other disk was there so I formatted. All was good so I went to disable the auto start of all my docker containers (The docker image file and appdata are all on the cache drive). Then I stopped and restarted the array. Which is where I got my cache drive issue. I thought that if one of the cache drives wasn't working I would still be able to see the data because the drives are mirrored but I don't see the data. Also disk 2 was formatted but now it has an unlocked yellow icon and the tool tip says "Device to be formatted" even though the file system stated on the drive is btrfs. I really need to fix my cache drive issue more so than anything else. I didn't even touch the cache drives and they were working after using the new configuration function and formatting disk 2. I know this because my dockers were all working. I mounted my cache drive in read only mode and my data is there but I still need to get it back into the array, hopefully without moving data around. PS: I have the license for 12 drives so I'm in the clear there although I have plugged in many drives over the years if that makes a difference. Thanks a bunch guys!

WiFi support could be had by passing through a WiFi device to a VM with a tiny Linux installation. That way the VM will give a network connection over WiFi to the rest of the server.

I love how easy it is to get VMs with pass through working out of the box. I would like to see the unraid docker interface work with docker-compose

Thank you for applying this patch. I was getting D3 on reboot of a Windows VM on a reference Asus 5700 XT but now it works! It appears to work even on Force Stop but I didn't do enough testing to confirm this. I also get the error for the audio. I think its because this patch is focused on the GPU part. qemu-system-x86_64: vfio: Cannot reset device 0000:25:00.1, no available reset mechanism. Am I right to assume that future Unraid updates will eventually overwrite the changes? My system specs are: MSI x570 Edge Wifi 3900x Reference Asus 5700 XT

Awesome it works! Never though to do it this way! Thank a bunch!

Just a note, sometimes in Windows 10 you need to enter the hostname in the username box when you login to a share ex: tower/username password

Hi everyone! I'm new to the forum. I have three Unraid servers and remote access has become a primary goal for me recently. I can't for the life of me find the commands that I can run via SSH to start and stop the array. For example I upgraded my server to 6.2 remotely and rebooted. Now I'm stuck with SSH access and in order to access the web gui I need to start Docker which needs the array to be up. One of my containers contains a proxy server that allows me to access the web gui. I'm guessing that on this server I forgot to enable "Auto Start Array" Thank you for your help!
