Broken?

Is this broken?

Docker verison: 17.05.0-ce, build 89658be
RexRax: v0.9.1
DVDCLI: Stable

dvdcli create --volumedriver=rexray/ebs --volumename=test123456789 --volumeopts=size=5 --volumeopts=iops=150 --volumeopts=volumetype=io1 --volumeopts=newFsType=ext4 --volumeopts=overwritefs=true

Results in:

WARN[0000] Unable to locate plugin: rexray/ebs, retrying in 1s 
WARN[0001] Unable to locate plugin: rexray/ebs, retrying in 2s

The reason I am using rexray/ebs is that the documents says it mimics that of the docker binary. Which requires rexray/ebs

docker volume create --driver rexray/ebs --name test-vol-1

^ This works

I have also tried with and without and changing to various other rexray examples.
