"No space left on device" after cleaning up disk / API

Post by RuudBurger »

Tonight a backup went to wrong folder (NFS share didn't mount) so my root drive got filled 100%.

1. First issue is that, my whole settings reset if this happens. Got a few friends that didn't have limit set and if there is no space left, ini writing fails.
Maybe make sure there is a few MB free before writing an empty ini?

2. So I cleanup the files, 30GB now left on and setup SAB like before. Still it fails. So I dig a little deeper and see the following error is returned when sending an nzb file:

I tried restarting SAB, with the same issue. Only a full reboot of the system fixed the issue.
I see the issue is in python (or the filesystem) itself, so you can't fix that. But you can at least catch the error and return a proper response from the api (json formated).

I got a few users of CouchPotato coming in with same issues where it reported "wrong api key" and they know the api key is the same. But as long as there isn't json returned, I don't have a way of catching the error and notifying the user.

1. The backup should be automatically used.
Could be a bug that prevents this from happening. I'll see what I can do.

I'm not sure what you are asking here.
What's probably happening is that the CherryPy web framework cannot handle the "disk full" situation.
There's not a lot I can do about that.
Release 0.8.0 will have a much more recent version of CherryPy, so that may improve in the future.
SABnzbd does show a warning in its own UI (unless you disabled that),
assuming it doesn't run into the same problem.
