|

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.ceph.com/issues/1722).
|
||||
After adding ``--debug-ms=1``, you can see which OSD is contacted.
|
||||
In the contacted OSD's log, you'll find the reason why this happens,
|
||||
and usually it is because the "rados classes" can't be loaded at runtime with ``dlopen``:
|
||||
|
||||
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.

|

|

This means the OSD could not find ``libcls_rbd.so``.
|
||||
You can customize the load path of these modules in ``ceph.conf`` with ``osd_class_dir``.
|
||||
By default, this is ``$libdir/rados-classes``, so when developing, you likely have to adjust the path.
