It seems that docker volume creation failed, cinder logs should provide more details why it failed. If I should guess, it's because your cinder volume size is not big enough (check with "vgs" command) - by default 25G volume per each node is created but you can tune size by tweaking following params in your env.yaml file (6G & 4G usually works fine for deployment testing):
master_docker_volume_size_gb: 6
node_docker_volume_size_gb: 4

ok thanks - that makes sense.
as it turns out I think I have a bigger issue in that the storage available on my cinder-volume is only 20G. The existing OSE and Origin setups we have typically use about 30-40G of docker images. I'm a little out of my depth here being a middleware person (although help from @paoloantinori) but I dont think I'm able to extend the cinder-volume size as the space (whilst isn't being used) has all been allocated to another volume.

PV /dev/sda2 VG rhel_integrationservices lvm2 [558.39 GiB / 60.00 MiB free]
PV /dev/sdb1 VG rhel_integrationservices lvm2 [1.64 TiB / 0 free]
PV /dev/loop1 VG cinder-volumes lvm2 [20.60 GiB / 20.60 GiB free]
Is there an option to not use Cinder and just use the local storage in the master and node VMs instead? Are there any other options you think might be worth exploring?

So it was my fault in the way I set up the host volumes in the first place, as a workaround to get me going, with the help of @jprovaznik and @paoloantinori ive run these steps. Not a recommended approach but good enough for me to continue.
mkdir /home/cinder-volumes
dd if=/dev/zero of=/home/cinder-volumes/cinder-volumes bs=1 count=0 seek=200G
losetup /dev/loop3 /home/cinder-volumes/cinder-volumes
vgextend cinder-volumes /dev/loop3
NOTE changes are not permanent, after an openstack reboot run..
losetup /dev/loop3 /home/cinder-volumes/cinder-volumes" and restart cinder-volume service
