Issue

• Openshift3.6 installer is failing when trying to install hosted registry to use Gluster with the traceback:

task path: /usr/share/ansible/openshift-ansible/roles/openshift_storage_glusterfs/tasks/glusterfs_common.yml:192
fatal: [node1.example.com]: FAILED! => {
    "failed": true
}

MSG:

the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'dict object' has no attribute 'results'

The error appears to have been in '/usr/share/ansible/openshift-ansible/roles/openshift_storage_glusterfs/tasks/glusterfs_common.yml': line 192, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:
