So my appdata cache is currently sitting at 923GB used of 966GB. This pool only has appdata storage (excluding plex which has its own pool) when I calculate the size of the data stored within the appdata folder it shows that there is only 396GB storage in it. This is the only folder on the drive... That I can see.

Is there any other reason this pool might be filling up? I've tried restarting docker.

I just figured this out. Kasm was the main culprit. I usually have my zfs datasets hidden. When i opened it up it showed that kasm had over 350Gb of data even though it wasnt being calculated during general operations. I'm guessing hidden files werent being shown. Anyway I dont use it often enough and got rid.
