General Parallel File System (GPFS) IBM: Proprietary: Linux, Windows and AIX A POSIX-compliant, high-performance, parallel filesystem. Support synchronous replication between attached block storage, and asynchronous replication to remote filesystems. Also support erasure coding on dual homed SAS attached storage, and distributed over multiple ...
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. It can be deployed in shared-disk or shared-nothing distributed parallel modes, or a combination of these.
As described in Google's patents, advantages of these global file systems include the ability to scale with the object storage, use snapshots stored in the object storage for versioning to replace backup, and create a centrally managed consolidated storage repository in the object storage.

Some examples include: MapR File System (MapR-FS), Ceph-FS, Fraunhofer File System (BeeGFS), Lustre File System, IBM General Parallel File System (GPFS), and Parallel Virtual File System. MapR-FS is a distributed file system that is the basis of the MapR Converged Platform, with capabilities for distributed file storage, a NoSQL database with ...

This is the foundation for a large set of planned features: snapshots, copy-on-write (COW) data, data deduplication, reflink copies, online data and metadata scrubbing, highly accurate reporting of data loss or bad sectors, and significantly improved reconstruction of damaged or corrupted filesystems. This work required changes to XFS's on-disk ...
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.
