Hi YoOrD,
That should be the right thing to do. You can contact your hosting admin for clearing up space in that disk. But I am not sure how good they would do that for you.
If they are unable to help you on that, then probably you can try shrinking the database and cleanup the unused space so that it doesn't fail to get data inserted.
May be you can take a look at this thread -
Shrink Log without SQL service restart However you can take a look at my last post at the bottom of that thread which has steps to clean up space.
This needs either SQL service restart or (detatch and attach DB commands) 4th and 5th step in that post, to free up the unused space. But if it is the live DB server, then this would not be the solution you are looking for. May be your hosting admin could help you on that.
Hope that helps.
Cheers!
