June 14Jun 14 HiThis all started with I kept getting the dreaded docker.img full utilization message, which I traced to plex.Did some of the changes that I found on SpaceInvader One's site, as well as another post with how to change the docker image storage into a directory. That messed up things more!Searched to see if I had an orphan image. I did. Removed it, Went in to add previous containers from inside docker and they added.This afternoon, they're gone. AND BONUS, when I tried to add them back, multiple ways, I get this message (I was trying to add Plex back in)docker: Error response from daemon: invalid output path: stat /var/lib/docker/overlay2/a8e0da990e4d3948d0723d05b47dd41b11f3787e3be0866885d61887e998d649: no such file or directoryNot sure what to do or what is going on. Jorge B., if you're still the docker guru, I could use your help again! Diagnostics attached.Thanks in advance for any help anyone can provide. tower-diagnostics-20260614-1255.zip
June 14Jun 14 Community Expert Changing to docker folder is not really the fix for growing docker img. Looks like you had given it 90GB and still filled it.The usual cause of filling docker.img is an application writing to a path that isn't mapped.I recommend going back to docker.img, 50G should be plenty, and reinstalling everything from previous apps. Then you can try to troubleshoot your dockers one at a time to see which is filling docker.imghttps://docs.unraid.net/unraid-os/troubleshooting/common-issues/docker-troubleshooting/
June 14Jun 14 Author Hi trurlThe problem is, I can't reinstal previous apps. That's where I get that error message as noted above and command failed messageI tried to recreate but there is no option to delete Docker vdisk fileAttached is docker screenshot
June 14Jun 14 Author OK, I deleted the docker directory, went back in to re-add my calibre container and received this message:docker: Error response from daemon: invalid output path: stat /var/lib/docker/overlay2/d3c500dceffb37757b6c41d871deb6310b99e2cd0532ab56fe48f5f30257a829: no such file or directoryRun 'docker run --help' for more informationThe command failed.I also had an orphan image pop up immediately (screenshot attached). I deleted it and went to add calibre again. Received same message as above, orphan also returned.
June 14Jun 14 Author Where am I looking to change to docker.img? I went to advance view in docker from settings, I don't see anything like that. Started docker, tried to load calibre again, and I didn't see anything like that before I tried to load it in calibre page Edited June 14Jun 14 by isrdude
June 14Jun 14 Author OK, Good news. Found where it switched to directory and switched to btfs vDisk and set size to 50mb. Loaded all my containers back and here is where it gets interesting. It appears it's putting plex data in one of my folders (attached screenshot).How would I proceed to find out which is definitively filling up my image as I originally thought it was Plex as it appears to be putting data into a folder within the container that it desires.

June 16Jun 16 Author No. I have reinstalled:PlexCalibreDiskspeedDokuMunin-ServerOverseerrTautulliPlex, Calibre, Overseerr, Tautulli are the only ones that I have started up
June 17Jun 17 Community Expert On the Docker page, click Container Size button at bottom and post the results, along with new diagnostics.
June 18Jun 18 Author OK...I've attached a clip of the container size and new diagnosticsthanks again tower-diagnostics-20260618-0641.zip
June 18Jun 18 Community Expert That all looks reasonable so far and only using 15% of docker.imgPost docker run for plex
June 18Jun 18 Author I added some data to calibre and Plex be interesting to see if there were any changes, Here is the docker rundocker run -d --name='Plex-Media-Server' --net='host' --pids-limit 2048 -e TZ="America/New_York" -e HOST_OS="Unraid" -e HOST_HOSTNAME="Tower" -e HOST_CONTAINERNAME="Plex-Media-Server" -e 'PLEX_CLAIM'='claim-xxx' -e 'PLEX_UID'='99' -e 'PLEX_GID'='100' -e 'VERSION'='latest' -l net.unraid.docker.managed=dockerman -l net.unraid.docker.webui='http://[IP]:[PORT:32400]/web' -l net.unraid.docker.icon='' -v '/mnt/cache/appdata/Plex-Media-Server/':'/transcode':'rw' -v '/mnt/user/Media':'/data':'rw' -v '/mnt/user/Media/2017 Stanley Cup Final Pens vs Sharks/':'/2017 Stanley Cup Final Pens vs Sharks':'rw' -v '/mnt/user/Media/Hallmark/':'/Hallmark':'rw' -v '/mnt/user/Media/Idi Only/':'/Idi Only':'rw' -v '/mnt/user/Media/Movies/':'/Movies':'rw' -v '/mnt/user/Media/Great Courses America'\''s Founding Fathers/':'/Great Courses America'\''s Founding Fathers':'rw' -v '/mnt/user/Media/2024 Car Shows/':'/2024 Car Shows':'rw' -v '/mnt/user/Media/Baseball/':'/Baseball':'rw' -v '/mnt/user/Media/Christmas Trains/':'/Christmas Trains':'rw' -v '/mnt/user/Media/Classic Car Restoration Videos/':'/Classic Car Restoration Videos':'rw' -v '/mnt/user/Media/College Football/':'/College Football':'rw' -v '/mnt/user/Media/Documentary/':'/Documentary':'rw' -v '/mnt/user/Media/Dominique Graduation Photos/':'/Dominique Graduation Photos':'rw' -v '/mnt/user/Media/Ed Only/':'/Ed Only':'rw' -v '/mnt/user/Media/Emily & Rich -

June 18Jun 18 Community Expert I xxx your claim token.That's a lot of path mappings!Do you use the DVR feature?
June 19Jun 19 Author Thank you, I missed that!No. I've never used the DVR feature. Never really had a need to use it.Yeah, I've heard that a lot about my mapping But it makes sense for me for the way I catalog and separate everything out for ease of manual search.
June 19Jun 19 Community Expert DVR and transcoding are the only ways Plex should be writing anything (except to its own database in Appdata).Post a screenshot of Plex Transcoder Settings (Show Advanced)
June 19Jun 19 Community Expert That is not the screenshot I was asking for. That information is already in docker run you posted.23 hours ago, isrdude said: -v '/mnt/cache/appdata/Plex-Media-Server/':'/transcode':'rw'I am talking about the Transcoder Settings within the Plex application
June 19Jun 19 Community Expert That looks OK too.The only other container you have that I use is DiskSpeed, and it doesn't have any paths except its appdata.On 6/18/2026 at 9:24 AM, trurl said:only using 15% of docker.imgWhat do you get now with this command line?df -h /dev/loop2
June 19Jun 19 Author This what I get:Filesystem Size Used Avail Use% Mounted on/dev/loop2 50G 6.8G 44G 14% /var/lib/dockerPart of me wonders if it isn't Calibre that is causing the issue. Things are looking OK now that I put everything back on. But it was OK before and then just started to grow. The only dockers that add data are plex and calibre. It is growing compared to what I posted abovecalibre 3.55 GB 15.4 MB 238 kB DiskSpeed 950 MB 3.49 MB 9.30 kB Plex-Media-Server 721 MB 363 MB 2.39 kB overseerr 718 MB 22.7 kB 2.20 MB munin-server 341 MB 470 kB 9.46 kB Doku 234 MB 5.04 MB 408 kB tautulli 203 MB 2.67 kB 22.1 MB Total size 6.72 GB 387 MB 24.9 MB
June 19Jun 19 Author Made a small tweak to Calibre from an online post I found. Changed the generic LIBRARYINTERNALPATH was going and sending it to my mapped calibre library. Appears it impacted the writable size from the above previous size:calibre 3.54 GB 3.19 MB 42.6 kB
