First symptom is that I noticed cards with history were showing no graphs. Then Samba addon erroring out. Then try to SSH in and got error creating /tmp//tmux-0 (no space left on device)
So I guess I need to delete my logs and history db. But uh… how?
No SMB
No SSH
Popping microSD into another machine (MacOS) just shows 42MB resin boot partition because hass.io
Once I did that I found what I needed in: resin-data/resin-data/homeassistant/home-assistant_v2.db
Others, who have a later version of hass.io from after the change from Resin to HassOS, I believe would find it at: hassos-data/supervisor/homeassistant/
Now, another thing I discovered is that I have some super huge backups in resin-data/backups (1Gb each, and they’re daily!) so I need to dig in and see what I did there.
I have this same problem and have found 6Gb worth of backups. I can read them using Paragon but is there any way to actually delete them? I don’t want to do anything apart from delete these back ups so I can free up space
