The online data migrations command in the release notes
needs to be corrected.
$ cinder-manage db online-data-migrations
usage: cinder-manage db [-h]
{online_data_migrations,purge,sync,version} ...
cinder-manage db: error: argument action: invalid choice:
'online-data-migrations' (choose from 'online_data_migrations',
'purge', 'sync', 'version')
"cinder-manage db online_data_migrations" is the right command.

upgrade:
|
|
- To get rid of long running DB data migrations that must be run offline,
|
|
Cinder will now be able to execute them online, on a live cloud. Before
|
|
upgrading from Ocata to Pike, operator needs to perform all the Newton
|
|
data migrations. To achieve that he needs to perform `cinder-manage db
|
|
online_data_migrations` until there are no records to be updated. To limit
|
|
DB performance impact migrations can be performed in chunks limited by
|
|
`--max_number` option. If your intent is to upgrade Cinder in a non-live
|
|
manner, you can use `--ignore_state` option safely. Please note that
|
|
finishing all the Newton data migrations will be enforced by the first
|
|
schema migration in Pike, so you won't be able to upgrade to Pike without
|
|
that.
