Heketi
RESTful based volume management framework for GlusterFS
...With Heketi, cloud services like OpenStack Manila, Kubernetes, and OpenShift can dynamically provision GlusterFS volumes with any of the supported durability types. Heketi will automatically determine the location for bricks across the cluster, making sure to place bricks and their replicas across different failure domains. Heketi also supports any number of GlusterFS clusters, allowing cloud services to provide network file storage without being limited to a single GlusterFS cluster.
