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 (bug #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.
