========= Ceph FS ========= .. important:: **WE DO NOT RECOMMEND USING CEPH FS IN PRODUCTION YET!** RBD, ``librbd``, RADOS, ``librados``, and RADOS Gateway are stable for production. The Ceph FS file system is a POSIX-compliant file system that uses a RADOS cluster to store its data. Ceph FS uses the same RADOS object storage device system as RADOS block devices and RADOS object stores such as the RADOS gateway with its S3 and Swift APIs, or native bindings. Using Ceph FS requires at least one metadata server in your ``ceph.conf`` configuration file. .. toctree:: Mount Ceph FS Mount Ceph FS as FUSE Mount Ceph FS in ``fstab``
