This class implements XrdOss interface for usage with a CEPH storage. It should be loaded via the ofs.osslib directive.
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.
