Description Eoghan Glynn 2012-09-25 10:43:57 UTC

Description of problem:

Volume detach fails with:

nova.api.openstack   File "/usr/lib/python2.7/site-packages/nova/volume/cinder.py", line 178, in begin_detaching
nova.api.openstack    cinderclient(context).volumes.begin_detaching(volume['id'])
nova.api.openstack AttributeError: 'VolumeManager' object has no attribute 'begin_detaching'

This is due to a mismatch between the nova code and the python-cinderclient, specifically the following commit is missing from the latter:

  https://github.com/openstack/python-cinderclient/commit/a4d46014


Version-Release number of selected component (if applicable):

python-cinderclient-0.2-2.fc18.noarch


How reproducible:

100%

Steps to Reproduce:
1. Create a volume
2. Attach volume to an instance
3. Detach volume
  

Actual results:

Attempt to detach fails with 500 Server Error.


Expected results:

Detach should suceed with 202 Accepted.

Comment 1 Eoghan Glynn 2012-09-25 11:12:47 UTC

Initial work-around pending rebuild of python-cinderclient packages:

  sudo yum install git
  git clone https://github.com/openstack/python-cinderclient.git $HOME/git
  sudo mv /lib/python2.7/site-packages/cinderclient /lib/python2.7/site-packages/cinderclient.old
  sudo ln -s $HOME/git/python-cinderclient/cinderclient/ /lib/python2.7/site-packages/cinderclient
  sudo service openstack-nova-api restart

Comment 2 Eoghan Glynn 2012-09-25 11:27:00 UTC

The same versioning problem causes boot-from-volume to fail with:

Build error: ['Traceback (most recent call last):\n', '  File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 493, in _run_instance\n    instance)\n', '  File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 725, in _prep_block_device\n    return self._setup_block_device_mapping(context, instance)\n', '  File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 432, in _setup_block_device_mapping\n    \'\', \'\', snapshot)\n', '  File "/usr/lib/python2.7/site-packages/nova/volume/cinder.py", line 218, in create\n', "TypeError: create() got an unexpected keyword argument 'imageRef'\n"]
