Next, copy the deploy/ directory to the master node of the cluster. download the GitHub extension for Visual Studio, Hello World with GlusterFS Dynamic Provisioning. Additionally, Heketi provides interfaces for day-2 operations like volume expansion, disk replacement, and node replacement. Heketi has evolved significantly with the recent release of v6.0.0. The provided secret must have type "kubernetes.io/glusterfs", e.g. Glusterfs. This will result in Glusterd2 exposing both the high level and the classical volume interfaces behind the same consistent API and CLI. heketi REST API (like the GlusterFS volume plugin) to create/manage volumes and Glusterd2 provides better scale for membership of servers in a trusted storage pool. The initial rounds of conversation around the planning of content for release 8 has helped the project identify one key thing – the need to stagger out features and enhancements over multiple releases.
