Ceph File System

CephFS achieves these goals through the use of some novel architecturalchoices. Notably, file metadata is stored in a separate RADOS pool from filedata and served via a resizable cluster of Metadata Servers, or MDS,which may scale to support higher throughput metadata workloads. Clients ofthe file system have direct access to RADOS for reading and writing file datablocks. For this reason, workloads may linearly scale with the size of theunderlying RADOS object store; that is, there is no gateway or broker mediatingdata I/O for clients.

For most deployments of Ceph, setting up a CephFS file system is as simple as:

Finally, to mount CephFS on your client nodes, setup a or kernel mount. Additionally, acommand-line shell utility is available for interactive access or scripting viathe .
