August 17, 20232 yr Hi, hopefully somebody can help me as I've googled and read multiple threads on this topic but didn't manage to solve it. I started getting warning about there not being enough space for docker - Fix common problems also flagging the same thing: Quote "Docker image file is getting full (currently 87 % used) [...] investigate the possibility of docker applications storing completed downloads / incomplete downloads / etc within the actual docker image" I read the linked thread I've checked every volume mapping I have, every single one is mapped to a /mnt/user/.. path I checked my download paths in-app for sabnzbd and qBitorrent, they are: /downloads & /incomplete-downloads mapped as: /downloads -> /mnt/user/data/downloads/ /incomplete-downloads -> /mnt/user/data/incomplete-downloads I removed some unused images which took me from 100% docker image space utilization to 87% I heard it could be a caching issue but unsure where to start - I did try doing a balance: Something I found in cadvisor: my cache setup for the relevant shares:
August 17, 20232 yr Hit advanced view on the docker tab and see if you have any orphaned images. Also posting your diagnostics would be good.
August 17, 20232 yr Author No orphaned images (although after a prune there were some I removed which is how I got from 100% to 87% utilization) Diagnostics attachedlakeshore-diagnostics-20230817-0910.zip

A common example is Plex writing to a temporary folder while transcoding.

A common example is Plex writing to a temporary folder while transcoding. This seems likely actually... This issue coincides with me switching to Plex from Emby and Plex was using /transcode which was not mapped (it was done via some ENV variable and had a path I didn't recognize set as default). Is there a way I can clean out all the accumulated data to see if it refills now that I've changed that? Edit: Down to 57% utilization after changing that Edited August 17, 20232 yr by Jelly
