"Docker Error"... "No space left on device"

I had a full node downloaded and blazing along.
But had to shut it off once I learned about the huge bandwidth and total data capacity that it requires each month, that my internet DSL plan doesn’t accommodate for, (especially after downloading the full node in the first place.)

REFERENCE = Monthly Bandwidth?

Near the end of last month, I had enough data remaining to fire it up again and at least have the node update. It got stuck at about 85% I think it was. Services wouldn’t update. I couldn’t figure out why. Shut it down at the last day of my DSL cycle.

Started it back up a day or two again (for this month), and now it won’t even boot past the screen I’m showing here.

So, I hope that explains where I’m at with this device.

In regards to your proposed “SSH” concept: I don’t know how to do that. Is that type of troubleshooting/recovery/deleting procedure in the DIY documentation?
thx
