Resolution

Go to crowbar Dashboard -> Barclamps -> OpenStack -> Nova and there click on "Raw" view, which opens up a json config.

Scroll down and look for the following section :
 "block_device": {
   "allocate_retries": 60,
   "allocate_retries_interval": 3
 },
The above are defaults, change allocate_retries from 60 to a higher value, for example 300.
Click 'save', and apply, and re-try launching the instance.

Note, these settings will be updated in '/etc/nova/nova.conf.d/100-nova.conf'  on controller and compute nodes:
block_device_allocate_retries = 300
block_device_allocate_retries_interval = 3

Cause

Nova expects the volume to be available within defined timeout.
With larger images it might take longer to create the volume than the default configured timeout.
