python-brickclient¶
- This element is aimed for providing cinder local attach/detach functionality.
- Currently the feature has a dependency on a known bug
https://launchpad.net/bugs/1623549, which has been resolved
and will be part of the upstream with the next release of
python-brick-cinderclient-ext. Note: Current version ofpython-brick-cinderclient-exti.e. 0.2.0 requires and update to be made in Line32 for/usr/share/python-brickclient/venv/lib/python2.7/site-packages/brick_cinderclient_ext/__init__.py: updatebrick-python-cinderclient-exttopython-brick-cinderclient-ext.
Usage¶
Pass the below shell script to parameter user-data and set
config-drive=true at the time of provisioning the node via
nova-boot to make cinder local attach/detach commands talk to your
cloud controller.
#!/bin/bash
FILE="/etc/bash.bashrc"
[ ! -f "$FILE" ] && touch "$FILE"
echo 'export OS_AUTH_URL="http://<controller_ip>:5000/v2.0"' >> "$FILE"
echo 'export OS_PASSWORD="password"' >> "$FILE"
echo 'export OS_USERNAME="demo"' >> "$FILE"
echo 'export OS_TENANT_NAME="demo"' >> "$FILE"
echo 'export OS_PROJECT_NAME="demo"' >> "$FILE"
exec bash
To attach: ``/usr/share/python-brickclient/venv/bin/cinder local-attach <volume_id>``
To detach: ``/usr/share/python-brickclient/venv/bin/cinder local-detach <volume_id>``
Alternatively, the same action can be completed manually at the node which does not require setting up of config drive such as:
/usr/share/python-brickclient/venv/bin/cinder \
--os-username demo --os-password password \
--os-tenant-name demo --os-project-name demo \
--os-auth-url=http://<controller_ip>:5000/v2.0 local-attach <volume_id>
