Bug #50852
Updated by Ramana Raja almost 3 years ago
MDSRank doesn't need to store the fs_name fetched from the MMDSMap message's map_fs_name. fs_name can be obtained by MDSRank from the mdsmap in the MMDSMap message. https://github.com/ceph/ceph/commit/51af2346fdf accidentally introduced the map_fs_name(file system's name) in the MMDSMap message. The original intention of the commit was to encode file system ID in the MMDSMap message as it's not in the mdsmap; the MDSRank would fetch the ID from the message and use it for security validation. It was later decided to use the fs_name and not the ID for security validation.
