fixes:
|

- |
|
||||
A change was added to the import API which provides time-based
|
||||
locking of an image to exclude other import operations from
|
||||
starting until the lock-holding task completes (see Bug
|
||||
1884596_). The lock is based on the task that we start to do the
|
||||
work, and the UUID of that task is stored in the
|
||||
``os_glance_import_task`` image property, which indicates who owns
|
||||
the lock. If the task holding the lock fails to make progress for
|
||||
60 minutes, another import operation will be allowed to steal the
|
||||
lock and start another import operation.

|
||||
After upgrading, deployments using the cinder backend should
|
||||
update their config to specify a volume type. Existing images on
|
||||
those backends will be updated at runtime (lazily, when they are
|
||||
first read) to a location URL that includes the store and volume
|
||||
type information.
