What did the show warnings; output ?
I didn't run it 
Ok, do you have .cfg and .ibd file for abuse_filter_action table that causes problems and could you share that with us ?
No I don't have them anymore as this happened a few days ago, as I tried twice and the second time it worked fine - which is also weird because nothing changed in the way I did it.
If you do not have error logs or anything else that would help to get bottom of this, I can't help you anymore. If you see this again please do not remove anything. On surface it could be that you did run out of disk space when exporting but not sure as above IO error is quite generic.
We did not run out of space.
But that is the whole point, that the error is quite generic and doesn't help to debug or troubleshoot the issue.
The point of this ticket was to see if it would be possible be a bit more verbose when showing this error so you can actually start digging on it
