+--name storage1 --opt=size=32

+dockercaptain1981@node1:~$ sudo docker volume create --driver rexray/gcepd

+dockercaptain1981@node1:~$

+
+We need to setup RexRay Plugin on all those nodes. It can be done manually or we have swarm-exec.sh script which can install RexRay in a single shot on all Swarm Nodes.
+
+```
+git clone https://github.com/mavenugo/swarm-exec
+sudo ./swarm-exec.sh docker plugin install –grant-all-permissions rexray/gcepd GCEPD_TAG=rexray
+```
+
+OR 
+
+You can run the below command on all the nodes
+
+```
+sudo docker plugin install --grant-all-permissions rexray/gcepd GCEPD_TAG=rexray
+```
