The Ceph Filesystem offers the POSIX-compliant distributed filesystem of any size that uses Ceph RADOS to store its data. To implement Ceph filesystem, you need a running Ceph storage cluster and at least one Ceph Metadata Serer (MDS) to manage its metadata and keep it separated from data, which helps in reducing complexity and improves reliability. The following diagram depicts the architectural view of CephFS and its interfaces:
libcephfs
libraries play an important role in supporting its multiple client implementations. It has the native Linux kernel driver support and thus clients can use native filesystem mounting, for example, using the mount
command. It has tight integration with SAMBA and support for CIFS and SMB. CephFS extends its support to Filesystem in USErspace (FUSE) using cephfuse modules. It also allows direct application interaction with the RADOS cluster using libcephfs libraries. CephFS is gaining popularity as a replacement for Hadoop...
