This patch is roughly an adaptation of Ia6fc9011ee6f5461f40a1307b72709d769814a79 for cinder. During an upgrade, cinder pins the version of RPC calls to the minimum seen across all services. This ensures that old services do not receive data they cannot handle. After the upgrade is complete, all cinder services are supposed to be reloaded to cause them to check again the RPC versions of services and use the new latest version which should now be supported by all running services. There is a second issue in that it takes some time for the upgraded services to update the cinder services database table with their new version. We need to wait until all cinder services have done this before the restart is performed, otherwise the RPC version cap will remain in place. There is currently no interface in cinder available for checking these versions, so as a workaround we use a configurable delay with a default duration of 30 seconds, as we do for nova. This change restarts all cinder services after an upgrade, after a 30 second delay. Closes-Bug: #1954932 Related-Bug: #1833069 Change-Id: I9164dc589386d2c2d4daf1bf84061b806ba9988d

# NOTE(mgoddard): After upgrading cinder, services will have an RPC version cap
|
|
# in place. We need to restart all services in order to allow them to use the
|
|
# latest RPC version. Ideally, there would be a way to check whether all cinder
|
|
# services are using the latest version, but currently there is not. Instead,
|
|
# wait a short time for all cinder services to update the version of their
|
|
# service in the database. This seems to take around 10 seconds, but the
|
|
# default is 30 to allow room for slowness.
