The Ceph file system (CephFS) is the POSIX-compatible distributed file system
running on top of Ceph's powerful and stable object store. This presentation
details recent performance measurements and stability testing of CephFS in
large-scale environments via virtual private servers in the cloud. Particular
emphasis is placed on exploring the benefits and stability of using multiple
metadata servers to distribute metadata load, a CephFS feature slated for
stability in the upcoming Luminous release. This talk will share the newer
methods used for rigorously testing CephFS in larger cloud environments by the
CephFS team and how we are measuring performance.
