This usually happens because your OSDs can’t find cls_rbd.so. They search for it in osd_class_dir, which may not be set correctly by default (http://tracker.newdream.net/issues/1722).
Most likely it’s looking in /usr/lib/rados-classes instead of /usr/lib64/rados-classes - change osd_class_dir in your ceph.conf and restart the OSDs to fix it.
