Sorry missed this reply! Finally got some time to try and resolve this. The USB drive is soldiered so I don't have the ability to shuck the drive and connect this way. Can you advice please if there's ANY way I can recover the contents of the pool and shift it to a new single 2TB SSD drive I have?

Thank you again for your time! root@box:~# fdisk -l /dev/sdd Disk /dev/sdd: 476.94 GiB, 512110190592 bytes, 1000215216 sectors Disk model: Tech Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Yes, one of the drives has always been connected via USB. I've been meaning to migrate back to one cache drive, internal SSD. If it's the USB one that's causing problems/damaged, would you be able to offer advice on how to migrate the data over and remove the USB drive from the pool, please? If I can get the array back online, I'll gladly just moved everything off the cache for time being.

Hello Jorge, thank you again! I left the scrub running overnight and immediately it was finding bad bits. It did however abort the scrub by itself overnight and attempting the scrub again simply does nothing (pressing the srub button had the page pending for a second or two, but nothing more happened). I powed off the server. Booting it back up today, the cache pool has also reverted to how it looked at the start of this thread. I had a go at bringing the cache pool back online using your steps above, as the terminal response from each step was the same, however after reaching this step: - I'm presented with this: root@box:~# btrfs fi show Label: none uuid: 94418e24-71a8-4933-a795-612a5f71ebf5 Total devices 1 FS bytes used 412.00KiB devid 1 size 2.00GiB used 228.75MiB path /dev/loop2 warning, device 2 is missing warning, device 2 is missing ERROR: cannot read chunk root Label: none uuid: adb84329-04d6-471b-afbd-2443872bcda4 Total devices 2 FS bytes used 1.88TiB devid 1 size 1.82TiB used 1.82TiB path /dev/sdi1 *** Some devices missing Am I right to assume one of the drives needs replacing, as it's damaged/on it way out? Is there any way to identify what drive of the two might be the cause? And if so, is there anyway to shift the cache from one drive onto the other, or both cache drives content onto the non-cache drives until I can replace the cache drives? Let me know if you feel I need to make a new thread for this! box-diagnostics-20241022-1236.zip

Running it now, already started making corrections. Thank you again!

Many many thanks, Jorge! Popped you a little beer money your way!

You genius, functioning again! Thank you! I manually stopped Docker in case there's any ongoing issues. box-diagnostics-20241021-1609.zip

I hope someone can help, please? I woke up this morning to find my cache pool of 2 devices were no longer mounted. I've tried stopping the array, un-assign both cache devices. Start array.

Unraid Server Version#: 6.11.5 Plex Server Version#: 1.31.2.6810 Docker Version: Tested on official, binhex and linuxserver Whenever I mount my webdav drive which appears to Plex as any other local directory, Plex begins to scan through the files, detecting credits, updating metadata, etc. After several minutes it locks up gets stuck in a ‘ERROR - Waited over 10 seconds for a busy database; giving up.’ loop and never progresses. I’ve completely wiped the container and tried again and again. It breaks every time I add this folder to the library after several minutes of scanning. Previously the container also messes with Unraid a lot. It becomes impossible to stop or remove through the GUI, as well as through the terminal using the kill command. Further Unraid refuses to shutdown. The only way to stop and remove the container is to ensure it isn't set to auto-start on boot, and then forcibly shutdown the server, and then power back up. The container can then be removed. Attempting to do anything with container throws the error, likely given it can't stop the container?: docker: Error response from daemon: Conflict. The container name "/Plex-Media-Server" is already in use by container "d86a32cb08a6240307d266349cbfe0556fb55105af5185b25d5f156db634b5f4". You have to remove (or rename) that container to be able to reuse that name. Please advise.

Have you tried: In the Steam game library, search for Cyberpunk 2077 and right-click on it with the mouse. In the right-click menu, select “Properties” to access the game’s properties. Inside the properties window, locate “Compatibility.” Then, check “Force the use of a specific Steam Play compatibility tool.”

Sadly not. I just don't understand it. No high CPU usage, no high RAM and no high disk usage. Sometimes disk usage shows 0 activity... when it should be loading a game?!

I'm running Unraid on my HP Proliant Gen8 Microsever. For whatever reason Unraid is seeing iLO as a unassigned drive. Because of this, this extra 'mount' (HP_iLO_LUN_00_Media_0_000002660A01-0:0) is bringing me 1 over my drive limit for my Unraid license, preventing my array from auto starting. Each boot I have to use the Unassigned Devies (/Plus) plugin to unmount this mount before being able to start the array. Is there any way I can stop this from happening? box-diagnostics-20221106-1017.zip

How do we enable Neko, please?

Thank you both for your replies. My games are stored on my cache. I'll give an unassigned drive a go!

Thank you for this amazing project!! I have noticed that there is a huge audio lag when accessing Steam via noVNC. Is there any way to resolve this? I've also noticed a number of games do not launch. Some without an error, or in the case of Portal: Any ideas why this might be?

My Docker memory has been slowly creeping up as I add containers. It was last hovering around 90% until I just added the Steam Headless container. How can I troubleshoot what is causing this? I've currently 27 live containers + 39 not running. I've stopped the Docker service for the time being as I can't imagine this is doing any good. Please advise. Edit: As per the attached screenshot, I tried upping the vdisk size from 30GB to 40GB. It was still at 100%. Further, the Docker service is refusing to start now. Is there any way I can start the Docker service without it starting any containers so I can begin troubleshooting? box-diagnostics-20220924-1515.zip
