#. **The MDS Map:** Contains the current MDS map epoch, when the map was
created, and the last time it changed. It also contains the pool for
storing metadata, a list of metadata servers, and which metadata servers
- are ``up`` and ``in``. To view an MDS map, execute ``ceph mds dump``.
+ are ``up`` and ``in``. To view an MDS map, execute ``ceph fs dump``.
Each map maintains an iterative history of its operating state changes. Ceph
Monitors maintain a master copy of the cluster map including the cluster
