Chapter 2. What's New in this Release?

User Serviceable Snapshot

The User Serviceability Snapshot feature is out of technology preview and is fully supported.You can now view and retrieve snapshots using the CIFS protocol for Windows clients. A new volume set option features.show-snapshot-directory is added to make the .snaps directory explicitly visible at the root of the share.

gstatus Command

The gstatus command provides an easy-to-use, high-level view of the health of a trusted storage pool with a single command. It gathers information by executing the GlusterFS commands, to gather information about the statuses of the Red Hat Storage nodes, volumes, and bricks. The gstatus command is a Technology Preview feature.

Remote Direct Memory Access

Remote Direct Memory Access (RDMA) support for communication between GlusterFS bricks and clients is out of technology preview and is officially supported. It fixes bugs and provides options to configure RDMA support for the new and existing volumes.

Red Hat Storage Object Store

Object Store has been rebased to Red Hat OpenStack Icehouse.

The Object Expiration feature is now supported in Object Storage. This feature allows you to schedule deletion of objects that are stored in the Red Hat Storage volume. For example, you might upload logs periodically to the volume, and retain those logs for only a specific amount of time. You can use the Object expiration feature to specify a lifetime for objects in the volume. When the lifetime of an object expires, it automatically stops serving that object at the specified time and shortly thereafter removes the object from the Red Hat Storage volume.
