GlusterFS is an open source, fully distributed storage solution for the world’s ever-increasing volume of unstructured data. It is a software-only, highly available, scale-out, centrally managed storage pool that can be backed by any POSIX filesystem that supports extended attributes, such as Ext3/4, XFS, BTRFS and many more.
This release provides many of the most commonly requested features including proactive self-healing, quorum enforcement, and granular locking for self-healing, as well as many additional bug fixes and enhancements.
Some of the more noteworthy features include:
- Unified File and Object storage - Blending OpenStack’s Object Storage API with GlusterFS provides simultaneous read and write access to data as files or as objects.
- HDFS compatibility - Gives Hadoop administrators the ability to run MapReduce jobs on unstructured data on GlusterFS and access the data with well-known tools and shell scripts.
- Proactive self-healing - GlusterFS volumes will now automatically restore file integrity after a replica recovers from failure.
- Granular locking - Allows large files to be accessed even during self-healing, a feature that is particularly important for VM images.
- Replication improvements - with quorum enforcement you are assured that your data has been written in at least the configured number of places before the file operation returns, allowing a user-configurable adjustment to fault tolerance vs performance.
