In this chapter, we will cover the following recipes:
- Understanding the Ceph Filesystem and MDS
- Deploying Ceph MDS
- Accessing CephFS via kernel driver
- Accessing CephFS via FUSE client
- Exporting Ceph Filesystem as an NFS
- ceph-dokan – CephFS for Windows clients
- CephFS – a drop-in replacement for HDFS
The Ceph Filesystem, also known as CephFS, is a POSIX-compliant filesystem that uses the Ceph storage cluster to store user data. CephFS supports the native Linux kernel driver, which makes CephFS highly adaptive across any flavor of the Linux OS. In this chapter, we will cover the Ceph Filesystem in detail, including its deployment, understanding the kernel driver and FUSE, as well as CephFS for Windows clients.
