Hi all, Today I have a problem using CephFS. I use firefly last release, with kernel 3.16 client (Debian experimental). I have a directory in CephFS, associated to a pool "pool2" (with set_layout). All is working fine, I can add and remove files, objects are stored in the right pool. But when Ceph cluster is overloaded (or for another reason, I don't know), sometimes when I remove a file, objects are not deleted in rados ! I explain : I want to remove a large directory, containing millions of files. For a moment, objects are really deleted in rados (I see it in "rados df"), but when I start to do some heavy operations (like moving volumes in rdb), objects are not deleted anymore, "rados df" returns a fixed number of objects. I can see that files are still deleting because I use rsync (rsync -avP --stats --delete /empty/dir/ /dir/to/delete/). Do you have an explanation for that ? I have an old pool "pool1" containing CephFS objects, but associated to nothing because files where deleted in CephFS a few weeks ago (directory associated to this pool does not exist any more). Thank you a lot.
