After installing Red Hat Storage, glusterd service will be started automatically on all the servers in your trusted storage pool. You can also manually start and stop glusterd service manually.

Red Hat Storage allows you to dynamically change the configuration of Red Hat Storage volumes without having to restart servers or remount Red Hat Storage volumes on clients. You can perform this type of elastic volume management using the glusterFS daemon called glusterd.

Using the glusterd command line, logical storage volumes are decoupled from physical hardware, allowing you to grow, shrink and migrate storage volumes without any application downtime. As storage is added, Red Hat Storage volumes are rebalanced across the trusted storage pool making it always available online regardless of changes to the underlying hardware.
