Further Analysis revealed that I am on Kubernetes 1.4, which has gci as image-type for the node. https://cloud.google.com/container-engine/docs/node-image-migration Since Kubernetes 1.4, gci image is defaulted for GKE Container Cluster and it is not supporting GlusterFS FileSystem as PV - Persistent Volume.
So, converted image-type from gci to container_vm
gcloud container clusters upgrade --image-type=container_vm "test-cluster"
Also, further note says that The following Kubernetes volume types that were supported in deprecated container-vm, are not yet supported in gci:
NFS
GlusterFS
iSCSI
