Some researchers have made a functional and experimental analysis of several distributed file systems including HDFS, Ceph, Gluster, Lustre and old (1.6.x) version of MooseFS, although this document is from 2013 and a lot of information are outdated (e.g. MooseFS had no HA for Metadata Server at that time).

DRBD layers logical block devices (conventionally named /dev/drbdX, where X is the device minor number) over existing local block devices on participating cluster nodes. . Writes to the primary node are transferred to the lower-level block device and simultaneously propagated to the secondary nod
In computing, the Global File System 2 (GFS2) is a shared-disk file system for Linux computer clusters. GFS2 allows all members of a cluster to have direct concurrent access to the same shared block storage, in contrast to distributed file systems which distribute data throughout the cluster.
Table Explanation. Software: The name of the application that is described; SMP aware: . basic: hard split into multiple virtual host; basic+: hard split into multiple virtual host with some minimal/incomplete communication between virtual host on the same computer
Ceph (pronounced / ˈ s ɛ f /) is a free and open-source software-defined storage platform that provides object storage, [7] block storage, and file storage built on a common distributed cluster foundation. Ceph provides distributed operation without a single point of failure and scalability to the exabyte level.
GPFS (General Parallel File System, brand name IBM Storage Scale and previously IBM Spectrum Scale) [1] is a high-performance clustered file system software developed by IBM. ...
DRBD is fully supported to facilitate replication between ESOS storage servers, and/or to create redundant ESOS storage server clusters. Virtual Tape Library (VTL) support by the mhVTL project. Three SSD caching solutions: EnhanceIO, bcache, and dm-cache (lvmcache).
Inktank Storage was the lead development contributor and financial sponsor company behind the open source Ceph distributed file system. [2] Inktank was founded by Sage Weil and Bryan Bogensberger and initially funded by DreamHost, [3] Citrix [4] and Mark Shuttleworth. [5] Red Hat acquired Inktank Storage for $175 Million in April 2014. [6]
