I'm still working on relocating temp files. I just ran DU. I suspect I just don't know how to read it properly but it looks like most of the 32GB (25.3G) is stored on the 8tb-ssd, which should have at least a terabyte free.
COREELEC:~ # du -xhs -d 1 /storage
4.0K /storage/downloads
2.7G /storage/.kodi
16.0K /storage/lost+found
4.0K /storage/tvshows
4.0K /storage/backup
4.0K /storage/pictures
12.0K /storage/picons
4.0K /storage/emulators
264.0K /storage/.config
4.0K /storage/screenshots
1.7M /storage/.cache
4.0K /storage/videos
4.0K /storage/music
4.0K /storage/.update
4.0K /storage/recordings
4.0K /storage/logfiles
4.0K /storage/.ssh
25.3G /storage/8tb-ssd
28.0G /storage
Also: This is LibreElec. I was running Coreelec, the network name was Coreelec, didn't want to break anything so I changed it to Coreelec.
Well, I looked closer. That storage/8tb-ssd is not my SSD. It's a directory with what I'm guessing is storage for pictures and data. Is there a way to trim that down a little? Or is 64GB a more reasonable amount of space?
