python-brickclientΒΆ

  • 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 of python-brick-cinderclient-ext i.e. 0.2.0 requires and update to be made in Line32 fo below script. /usr/share/python-brickclient/venv/lib/python2.7/site-packages/brick_cinderclient_ext/__init__.py update “brick-python-cinderclient-ext” to “python-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. [Example of Config Drive Script]

    #!/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>
