I am now facing issues in creating volumes from the dashboard. Here is volume log file for reference : 2013-05-09 15:24:49 ERROR [cinder.service] Unhandled exception Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/cinder/service.py", line 224, in _start_child self._child_process(wrap.server) File "/usr/lib/python2.6/site-packages/cinder/service.py", line 201, in _child_process launcher.run_server(server) File "/usr/lib/python2.6/site-packages/cinder/service.py", line 95, in run_server server.start() File "/usr/lib/python2.6/site-packages/cinder/service.py", line 342, in start self.manager.init_host() File "/usr/lib/python2.6/site-packages/cinder/volume/manager.py", line 143, in init_host self.driver.check_for_setup_error() File "/usr/lib/python2.6/site-packages/cinder/volume/drivers/lvm.py", line 78, in check_for_setup_error raise exception.VolumeBackendAPIException(data=exception_message) VolumeBackendAPIException: Bad or unexpected response from the storage volume backend API: volume group cinder-volumes doesn't exist It says - volume group cinder-volume does not exist.
