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 :
- the path can be prepended with userId and pool. Syntax is : [[userId@]pool:]<actual path>="">
- the XrdOucEnv parameter, when existing, can have 'cephUserId' and/or 'cephPool' entries
- the ofs.osslib directive can provide an argument with format : [userID@]pool
- default are 'admin' and 'default' for userId and pool respectively
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.
