May 23, 20224 yr What do you do if you deleted the docker.img file and rebuilt and then went to previously installed apps and find that none of the docker are there. WIll I have to manually reinstall all of these dockers or is there a way to recreate these with all my old settings? I upgraded to 6.10 this past week and installed a new precleared drive and woke up to none of the dockers working. So I did the Docker rebuild first...

The settings for previously installed apps are in the config folder on your flash drive just like all of your other settings. Did you make a new Unraid install without your configuration?
May 23, 20224 yr I did not make a new Unraid install I just uploaded through GUI to 6.10 and then upgraded again today when the pop up came up. I was upgrading an old 2TB drive with a new 6TB drive and I coppied all the data from old drive to a current drive. I then removed the old drive in the config and rebuilt parity with one less drive. all checked out. I then precleared the new drive and added it to the array and formatted it as normal. All checked out. noticed none of my dockers were showing in the dashboard (don't know if that was before or after but they were all on when I went to bed last night as the new drive was finishing Post Read. Remembered last time this happened a few years ago about the rebuilding docker.img. So I did that. but when I went to previous apps location it only had two plugins listed and dockers was greyed out. Unfortunately my flash back up is way out of date. Brain fart and I didn't backup before upgrade. I hadn't upgraded in awhile. I think I was on 6.5 still. But anyway on the app page after deleting and re enabling docker image in settings page I get this at the top. EDIT: found this but here is my cache info Edited May 23, 20224 yr by Japes

May 23, 20224 yr Community Expert Cache filesystem is going read-only: May 23 10:31:46 Tower kernel: BTRFS info (device sde1): forced readonly Best way forward to make sure it's fixed is to backup anything else important on cache and re-format it, then restore the data and re-create the docker image.
May 23, 20224 yr I figured so that's what I was in the process of doing so I'' report back when that's done. Starting with all the family photos since it looks like the mover hasn't moved those in quite awhile Edited May 23, 20224 yr by Japes
May 24, 20224 yr Everything seems to be going ok so far. Only one of the dockers so far needed to be re set up like new.

You must always have another copy of anything important and irreplaceable.

It was more a comment of that seeming weird since I haven't added photos to the server in over a week and Mover is supposed to have been run nightly so the Cache drive must have been having issues for at least a week. So, the Docker weirdness I was experiencing last week kind of makes sense now.

December 13, 20223 yr My filerun stopped working and would not restart, while most other dockers were still ok. Grafana and Mosquitto could not start. So I turned docker service off, and back on, it reported the same issue. Rebooted, same issue. I tried to backup appdata with CA plugin, but the status part always stops at filerun/system/data. I will leave it overnight and see if it gets any further. I am downloading diagnostic, but it is stuck at "lsof -Pni 2>/dev/null|todos >'/realserver-diagnostics-20221212-1807/system/lsof.txt'"
January 29, 20233 yr complete noob to unraid. brand new install. this docker failing to start stuff is not giving me the warm and fuzzies about paying for this once my trial runs out. any assistance would be appreciated.

January 29, 20233 yr I also seen this from JorgeB in another thread.... "Remove any custom docker networks and try again, if it doesn't help reset lan settings by deleting/renaming /boot/config/network.cfg then reboot." didnt have any?? Rebooted and only ran diagnostics sadie-diagnostics-20230128-2246.zip Edited January 29, 20233 yr by Colin Betzel additions
January 29, 20233 yr Community Expert Not sure what's going on there. docker.img appears to mount, then immediately unmounts. Try recreating docker.img then post new diagnostics https://wiki.unraid.net/Manual/Docker_Management#Re-Create_the_Docker_image_file
