This patch provides script to migrate data from consistencygroups to
groups and from cgsnapshots to group_snapshots.
In the migration script, it creates a default_cgsnapshot_type
for migrating data and copies data from consistency groups to
groups and from cgsnapshots to group_snapshots. Migrated consistency
groups and cgsnapshots will be removed from the database.
It depends on the following patch that adds generic code for
online data migrations:
https://review.openstack.org/#/c/330391/
Run the following command to migrate CGs:
cinder-manage db online_data_migrations
--max_count <max>
--ignore_state
max_count is optional. Default is 50.
ignore_state is optional. Default is False.
