upgrade_levels options are used to set version cap for RPC
|
|
messages sent between different nova services.
|
|
|
|
By default all services send messages using the latest version
|
|
they know about.
|
|
|
|
The compute upgrade level is an important part of rolling upgrades
|
|
where old and new nova-compute services run side by side.
|
|
|
|
The other options can largely be ignored, and are only kept to
|
|
help with a possible future backport issue.

|

Compute RPC API version cap.
|
|
|
|
By default, we always send messages using the most recent version
|
|
the client knows about.
|
|
|
|
Where you have old and new compute services running, you should set
|
|
this to the lowest deployed version. This is to guarantee that all
|
|
services never send messages that one of the compute nodes can't
|
|
understand. Note that we only support upgrading from release N to
|
|
release N+1.
|
|
|
|
Set this option to "auto" if you want to let the compute RPC module
|
|
automatically determine what version to use based on the service
|
|
versions in the deployment.
|
|
|
|
Possible values:
|
|
|
|
* By default send the latest version the client knows about
|
|
* 'auto': Automatically determines what version to use based on
|
|
the service versions in the deployment.
|
|
* A string representing a version number in the format 'N.N';
|
|
for example, possible values might be '1.12' or '2.0'.
|
|
* An OpenStack release name, in lower case, such as 'mitaka' or
|
|
'liberty'.
