There is 6TB on the DVR drive. I am using Channels DVR on Unraid as a docker container and the client is Channels on the Nvidia Shield. The Shield has 5GB available.
The Nvidia Shield may have 5GB free now, but check it when you get the error.
Also, posting a screenshot of the error would help.
The developers may ask you to submit diagnostics from the Channels app on the Nvidia Shield next time it happens.
You can also change settings so the buffer is on the server, instead of on the client.
Set Settings > Playback > Streaming Quality > Original Quality Delivery to Stream
I had the same issue. A few nights in a row, I’d wake up and see the black “storage full” screen, even though I wasn’t recording anything and had plenty of space on the drive.
Eventually, I realized there was a small issue with the app’s cache or recording settings. After clearing the cache and restarting the system, the problem was fixed. It might help to check if there are any unsaved recordings taking up space.
If it’s still happening, maybe try checking the drive to make sure there’s no issue with formatting or space calculation. Hope that helps!
