Expected/desired behavior

Default options shouldn't be exposed

Details on how to reproduce (minimal and precise)

create a PVC without brick mux enabled.

• Operating system used: Centos 7.4
• Glusterd2 compiled from sources, as a package (rpm/deb), or container: Container
• Using External ETCD: (yes/no, if yes ETCD version): external etcd
• If container, which container image:
• Using kubernetes, openshift, or direct install: Kubernetes
• If kubernetes/openshift, is gluster running inside kubernetes/openshift or outside:

Other useful information

• glusterd2 config files from all nodes (default /etc/glusterd2/glusterd2.toml)
• glusterd2 log files from all nodes (default /var/log/glusterd2/glusterd2.log)
• ETCD configuration
• Contents of uuid.toml from all nodes (default /var/lib/glusterd2/uuid.toml)
• Output of statedump from any one of the node

Useful commands

• To get glusterd2 version

[root@gluster-kube3-0 /]# glusterd2 --version glusterd version: v6.0-dev.92.git4d140ab git SHA: 4d140ab go version: go1.11.2 go OS/arch: linux/amd64 ```

• To get ETCD version

/ # etcd --version etcd Version: 3.3.8 Git SHA: 33245c6b5 Go Version: go1.9.7 Go OS/Arch: linux/amd64 / #

```

• To get output of statedump

  curl http://glusterd2-IP:glusterd2-Port/statedump
