Release note explaining ``cinder-manage db online-schema-migrations`` was created back in Newton, and was referring to wrong release names. This commit fixes that by changing "Newton" to "Ocata" and "Ocata" to "Pike". Change-Id: Ia52fe964ad37fab0271bda3057cc16fdd4848ae1

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.
