Announcing Gluster Storage Release 4.1 for Oracle Linux 7

Simon Coter
Director of Product Management

The Oracle Linux and Virtualization team is pleased to announce the release of Gluster Storage Release 4.1 for Oracle Linux 7. Gluster Storage is a runtime component of the Oracle Linux Cloud Native Environment.

Gluster Storage is an open source, POSIX compatible file system capable of supporting thousands of clients while using commodity hardware. Gluster provides a scalable, distributed file system that aggregates disk storage resources from multiple servers into a single global namespace. Gluster provides built-in optimization for different workloads and can be accessed using either an optimized Gluster FUSE client or standard protocols including SMB/CIFS. Gluster can be configured to enable both distribution and replication of content with quota support, snapshots, and bit-rot detection for self-healing.

Gluster 4.1 for Oracle Linux 7 introduces support for:

  • Either the Unbreakable Enterprise Kernel (Release 4 and higher) and the Red Hat Compatible Kernel
  • x86_64 and aarch64 architectures
  • Upgrades from an existing Gluster 3.12 configuration
  • NFS-Ganesha, which provides NFSv3, v4, v4.1, and pNFS server support for Gluster volumes

This release also includes a technology preview of Heketi, which provides a RESTful management interface to manage the lifecycle of GlusterFS volumes.

Notable enhancement and new features:

  • Management
    • Samba volumes can be made inaccessible to clients without stopping the same smb.conf. This enhancement can also preserve changes to smb.conf, when configured externally
    • GlusterD2 brings initial support for rebalancing, snapshots, intelligent volume provisioning (This is a technology preview and still experimental)
  • Monitoring
    • GlusterFS 4 offers a lightweight method to access internal information and avoids the performance penalty and complexities of previous approaches
    • GlusterFS 4.1 introduces additional metrics to help determine the effectiveness of the xlator in various workloads
  • Performance
    • Gluster FUSE mounts now support FUSE extension to leverage the kernel "write-back cache"
    • Improved performance when there are frequent metadata updates in the workload, typically seen with shared volumes
    • Processing FUSE read requests can be done in parallel
    • Better workload distribution on reads for replicate-based volumes
  • Standalone
    • Utime feature enables Gluster to maintain consistent change and modification time stamps on files and directories across bricks
    • Thin Arbiter volumes in Gluster (part of the GlusterD2 technology preview)
    • Automatically configure backup volfile servers in clients (part of the GlusterD2 technology preview)

Installation

Gluster Storage is available on the Unbreakable Linux Network (ULN) and the Oracle Linux yum server. It is currently available for the x86_64 and aarch64 architectures and can be installed on any Oracle Linux 7 server running either the Red Hat Compatible Kernel (RHCK) or the Unbreakable Enterprise Kernel (UEK) Release 4 or 5. 

For more information on hardware requirements and how to install and configure Gluster, please review the Gluster Storage for Oracle Linux Release 4.1 documentation.

Support

Support for Gluster Storage is available to customers with an Oracle Linux Premier support subscription. Refer to Oracle Linux 7 License Information User Manual for information about Oracle Linux support levels.

    Great to see GLuster on Unbreakable Enterprise Kernel get updated!

    Since Oracle Linux is an IBM Linux clone, will GLuster be coming to Oracle's Solaris 11.4???

    Hi David,

    there is no plan, actually, to get Gluster available on Solaris/SPARC platform.
    Thanks

    Simon
