Detailed Description

This class implements XrdOssDF interface for usage with a CEPH storage.

This plugin is able to use any pool of ceph with any userId. There are several ways to provide the pool and userId to be used for a given operation. Here is the ordered list of possibilities. First one defined wins :

Note that the definition of a default via the ofs.osslib directive may clash with one used in a ofs.xattrlib directive. In case both directives have a default and they are different, the behavior is not defined. In case one of the two only has a default, it will be applied for both plugins.
