A Red Hat Gluster Storage trusted storage pool consists of nodes, volumes, and bricks. The get-state command outputs information about a node to a specified file.
Using the command line interface, external applications can invoke the command on all nodes of the trusted storage pool, and parse and collate the data obtained from all these nodes to get an easy-to-use and complete picture of the state of the trusted storage pool in a machine parseable format.
