no space left on device
If your Edison has been running smoothly for a while, chances are that the filesystem is filling up.
- slowly: due to normal operation, and even maintenance,
- quickly: if something is off, and loggin processes are trying to tell you about it, but noone takes note of the logs...
Fortunately, there are some quick actions you can take to reclaim space from the most likely culprits before debugging the problem that caused your filesystem to fill up.
