Elliptics network - a distributed hash table storage got initial fsck implementation. Actually I can only say this is a data checker, which does not try to recover if something is broken.

And it only works with provided text log and only for non-transactional objects uploaded, i.e. what is generated with HTTP fastcgi frontend. Fsck checks number of copies in the storage according to config and reports them to the user, which in turn can manually start upload process if number does not match.

This is a very first step of course and things will be improved with time, but it is already quite handy for administrators. To date elliptics network storage still requires manual intervention for 100% guarantee that storage contains needed number of copies, although in some cases it can be done automatically.
