Cinder uuid-mapping-patch

it will be patched in cascading level's control node

Cascading level node can manage volume/snapshot/backup/ in cascaded level node, because of the mapping_uuid stored in cascading level represent the relationship of volume/snapshot/bakcup

Key modules

  • adding mapping_uuid column in cinder volume /cinder snapshot /cinder backup table, when cinder synchronizes db:

    cinder\db\sqlalchemy\migrate_repo\versions\023_add_mapping_uuid.py cinder\db\sqlalchemy\migrate_repo\versions\024_snapshots_add_mapping_uuid.py cinder\db\sqlalchemy\migrate_repo\versions\025_backup_add_mapping_uuid.py cinder\db\sqlalchemy\models.py

Requirements

  • openstack icehouse has been installed

Installation

We provide two ways to install the mapping-uuid-patch code. In this section, we will guide you through installing the instance_mapping_uuid patch.

  • Note:

    • Make sure you have an existing installation of Openstack Icehouse.
    • We recommend that you Do backup at least the following files before installation, because they are to be overwritten or modified:

  • Manual Installation

    • Make sure you have performed backups properly.

    • Navigate to the local repository and copy the contents in 'cinder' sub-directory to the corresponding places in existing nova, e.g. cp -r $LOCAL_REPOSITORY_DIR/cinder $NOVA_PARENT_DIR (replace the $... with actual directory name.)

    • synchronize the cinder db.

      mysql -u root -p$MYSQL_PASS -e "DROP DATABASE if exists cinder;
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY $MYSQL_PASS;
GRANT ALL PRIVILEGES ON *.* TO 'cinder'@'%'IDENTIFIED BY $MYSQL_PASS;
cinder-manage db sync

    • Done. The cinder proxy should be working with a demo configuration.

  • Automatic Installation

    • Make sure you have performed backups properly.

    • Navigate to the installation directory and run installation script.

      cd $LOCAL_REPOSITORY_DIR/installation
sudo bash ./install.sh

      (replace the $... with actual directory name.)
