Michael Marth commented on OAK-2879:
------------------------------------
[~mduerig], I wonder if a log message is enough. When the compacation runs
frequently such a log message might not be noticed in time and thus users would
run into the out of disc problem anyway. How about aborting compaction or
requiring a manual "force" setting?
> Compaction should check for required disk space before running

> In the worst case compaction doubles the repository size while running. As
> this is somewhat unexpected we should check whether there is enough free disk
> space before running compaction and log a warning otherwise. This is to avoid
> a common source of running out of disk space and ending up with a corrupted
> repository.
