Hi guys, I've been having some issues crop up with my server, and I finally got around to checking the Fix Common Problems app to see what's what. I've attached the zip file of the diagnostics, but the symptoms are:

• Docker apps frequently stopping, in particular a Minecraft docker/server, and lately, I've tried to add an additional mapped drive/folder to my Emby docker, and it'll cause the server to hang for a certain period, seems like hours but could be 20+ minutes before I'm able to access the Unraid GUI. The only fix I've had to that is to not have a second mapped folder, which works fine.

Otherwise, my system works pretty great 99% of the time, but I lack the know-how to solve this one. 

Thanks for any advice!

 

Edit: I just perused a thread regarding limiting docker apps' memory, and I've set the (potential) offenders (emby, minecraft, nzbget) to a 4 gb limit on memory. I hope that's all it is and not some hardware fail, but if the diagnostics reveal something else, please let me know. Thanks!

Why do you have 200G docker.img? 20G is often more than enough, and it looks like you are currently using less than 3G.

 

Have you had problems filling docker.img? Making it larger won't fix problems filliing it, it will only make it take longer to fill. The usual cause of filling docker.img is an application writing to a path that isn't mapped to host storage.

 

Your appdata has files on the array.

I have no idea how/why my docker.img is that big, and I wasn't aware there could be problems filling it lol. Is there somewhere to modify that?
I've tried to move the appdata stuff off the array, but I can't quite figure it out. I gather it's one of those not great but not horrible things to do so I've kinda just left it.

Thanks for the tips!

You (or whoever set this up) must have set it that large since 20G is the default. You would have to recreate it at a smaller size if you don't want to waste all that space.

Nothing can move open files, so Docker has to be stopped in Settings. And, for your specific case, you have to set appdata to:

Primary: cache; Secondary: array; Mover action: array->cache

 

Similarly for domains share if you have space to keep it off the array. You have to disable VM Manager in that case to allow it to be moved.
