Section Number and Name: 

6.1.3.2. Upgrading the Red Hat Gluster Storage Pods

Describe the issue: 

The below command mentioned in the deployment doc is incorrect:

~~~
# for eachVolume in gluster volume list; do echo $eachVolume; gluster volume set $eachVolume server.tcp-user-timeout 42 ; done

For example:

# for eachVolume in gluster volume list; do echo $eachVolume; gluster volume set $eachVolume server.tcp-user-timeout 42 ; done
  volume1
  volume set: success
  volume2
  volume set: success
~~~

This command is mentioned multiple times in the doc. All the section numbers containing command is mentioned above.

Suggestions for improvement: 

It should be:

# for eachVolume in $(gluster volume list); do echo $eachVolume; gluster volume set $eachVolume server.tcp-user-timeout 42 ; done
