This usually happens because your OSDs can't find ``cls_rbd.so``. They
|
2011-12-14 18:47:38 +00:00
|
|
|
search for it in ``osd_class_dir``, which may not be set correctly by
|

|
|
|
default (http://tracker.ceph.com/issues/1722).

Most likely it's looking in ``/usr/lib/rados-classes`` instead of
|
|
|
|
|
``/usr/lib64/rados-classes`` - change ``osd_class_dir`` in your
|
2014-03-08 23:01:40 +00:00
|
|
|
``ceph.conf`` and restart the OSDs to fix it.
