And to delete the non-used ones ? Not yet -- fsck and repair are under development. The recent "Question on cephfs recovery tools" thread gives some sense of the current state of these. The tools that enable checking if an inode is linked are not yet merged into master (various pull requests are in flight), and definitely not sufficiently tested to recommend you using on this cluster. If you have relatively few files, you can do this stuff "by hand" with some scripting. Do an "ls -lRi", build a list of all the inodes that are linked, then do a "rados -p data ls" and check if each object's inode number is in the list of linked inodes. That's going to be really slow though! One of the features of the real recovery tools is sharding the work out to multiple workers to make it through in more reasonable time.
