Stuck in diagnostic mode after gateway timeout

I have been running a bitcoin node for over a year and it’s now stuck in diagnostic mode after gateway timeout.

Error: write/var/lib/containers/storage/overlay/metacopy-check2737866039/l1/.top-f4002600667:no space left on device

Can someone help me get my node up and running again please.

It says in the error message that you’ve run out of disk space.

You’d need a bigger disk. You’d add a new drive, and get an adapter for the old drive, then run through the transfer guide…
