Chapter 4. Technology Previews
This chapter provides a list of all available Technology Preview features in this release.
Technology Preview features are currently not supported under Red Hat Gluster Storage subscription services, may not be functionally complete, and are generally not suitable for production environments. However, these features are included for customer convenience and to provide wider exposure to the feature.
Customers may find these features useful in a non-production environment. Customers are also free to provide feedback and functionality suggestions for a Technology Preview feature before it becomes fully supported. Errata will be provided for high-severity security issues.
During the development of a Technology Preview feature, additional components may become available to the public for testing. Red Hat intends to fully support Technology Preview features in the future releases.
Note
All Technology Preview features in Red Hat Enterprise Linux 6.7, 7.1, and 7.2 are also considered technology preview features in Red Hat Gluster Storage 3.1. For more information on the technology preview features available in Red Hat Enterprise Linux 6.7, see the Technology Previews chapter of the Red Hat Enterprise Linux 6.7 Technical Notes: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/6.7_Technical_Notes/technology-previews.html
4.1. Replicated Volumes with Replica Count greater than 3
The replicated volumes create copies of files across multiple bricks in the volume. It is recommended that you use replicated volumes in environments where high-availability and high reliability are critical. Creating replicated volumes with replica count more than 3 is under technology preview.
