Announcing Gluster Storage Release 6 for Oracle Linux
The Oracle Linux and Virtualization team is pleased to announce the release of Gluster Storage Release 6 for Oracle Linux, bringing customers higher performance, new storage capabilities and improved management.
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 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.
New Features
Gluster Storage Release 6 introduces support for the following important capabilities:
- Gluster Geo-Replication: Geo-replication provides a continuous, asynchronous, and incremental replication service from one site to another over a LAN, WAN or across the Internet.
Geo-replication uses a master–slave model, whereby replication and mirroring occurs:- Master – the geo-replication source GlusterFS volume
- Slave – the geo-replication target GlusterFS volume
- Session - Unique identifier of Geo-replication session
Differences between Replicated-volumes and Geo-replication:
| Replicated Volumes | Gluster Geo-Replication |
|---|---|
| Mirrors data across clusters | Mirrors data across geographically distributed clusters |
| Provides high-availability | Ensure backing up of data for disaster and recovery |
| Synchronous Replication (each and every file operation is sent across all the bricks) | A-synchronous Replication (checks for the changes in files periodically and syncs them upon detecting differences) |
- Support for Oracle Linux 8: Gluster Storage Release 6 for Oracle Linux introduced the support for Oracle Linux 8 with Red Hat Compatible Kernel, in addition to Oracle Linux 7
Gluster Storage Release 6 for Oracle Linux 8 has been build as an Application Stream Module named glusterfs; module profiles available are:
- Server
- Client
An additional glusterfs-developer module is available as a technology preview and introduces the option to leverage gluster-ansible RPMS to automate gluster deployment and management by Ansible.
Additional enhancements in Gluster Storage Release 6 for Oracle Linux:
- Several stability fixes
- Client side inode garbage collection
- Performance Improvements
Gluster Storage Release 6 for Oracle Linux is today supported on following configurations:
| Platform | Operating System Release | Minimum Operating System Maintenance Release | Kernel |
|---|---|---|---|
| x86_64 | Oracle Linux 8 | Oracle Linux 8 Update 1 | Red Hat Compatible Kernel (RHCK) |
| x86_64 | Oracle Linux 7 | Oracle Linux 7 Update 7 |
