OSD class path issues¶

create error: error 5: Input/output error
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).
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.
