Docker image disk utilization of 99%

[Zonediver]

Hi experts,

 

i have a strange problem with the docker image.

unraid reported a utilization of 99 (!) % and i cant imagine why.

I use only 5 dockers - two are running - plex and tautulli.

The Image has a size of 10,49GB...

This happend now the 3rd time - if someone know whats going on here, please give me a hint.

Thanks for your help

Something was clearly writing stuff to your docker image from 16:29 to 16:40, continuously. If you only have Plex and Tautulli running during that period then one of those 2 dockers are writing stuff directly to the docker image so probably incorrect mapping.

 

I would suspect it to be Plex. File sync?

File sync is not active - this happens very rarely... 3x in 8 months...

The mappings aren't the only thing you need to consider though. It is the paths specified in the application, and whether or not they correspond to mapped storage. Common mistakes are specifying a path in the application that doesn't exactly match a container path in upper/lower case, and specifying a relative path in the application (what is it relative to?)

 

I don't use tautulli but from looking at it I assume it only writes to appdata.

 

The main ways plex will write to a path other than appdata are transcoding and DVR if you use either of those features. The new "skip intro" feature also seems to be a problem for some.
