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.
