+Dependencies:
+ - Executed on all nodes. 
+    * The GlusteFS servers are configured on all storage servers. 
+    * The GlusterFS clients on all the servers
+    * The volumes are created in the configured domains
+ - Expects that partition for bricks is already prepared
+
+Parameters:
+  glusterfs_version: should be defined (without dot, like 39)
+  glusterfs_transport: Transport to use, defaults to rdma
+
+  glusterfs_network: CIDR for gluster internal Infiniband network
+    - if 192.168.12.0/24 is specified, the 'ipekatrin1' storage node will be mapped '192.168.12.1' IP, etc.
+  glusterfs_servers: List of storage servers in glusterfs_network
+  glusterfs_bricks_path: The location to store volume bricks, defaults to 'ands_data_path'/glusterfs
+  glusterfs_domains: Volume configuration
+
+Facts:
+
+Actions:
+ - Installs appropriate GlusterFS repositories (to match specified version)
+ - Installs required packages, only native clients on the servers without storage
+ - Enables firewalld if necessary and allows GlusterFS service
+ - Configures SELinux, etc. 
+ - Probes all storage nodes using internal Infiniband IPs
+ - Creates requested volumes and mounts them
