Public bug reported:

Project > Volume > Create Volume fails and only shows a generic 'Error'
in the table.  User has to go to /var/log/cinder/volume.log  to see why
it failed.  It would be nice to propagate the error message (or
something) like the one in the volume.log: "Volume group "cinder-
volumes" has insufficient free space (1279 extents): 1280 required.\n'"

I believe Instances has a nice way of letting user know the failure... it will show a new section in the Instances table:
