It seems to me that there is a lot of logical overlap between this and the MDS directory hotspotting/sharding. As I understand it, the MDS directory sharding is a manual process (from http://ceph.com/dev-notes/cephfs-mds-status-discussion/). >From a high level, a POSIX directory is just a bucket that can contain other buckets and objects with several pre-defined pieces of metadata. It seems like it might be a good idea to pull the MDS guys in to this discussion. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
