@Freyes: I am not sure I understand your comment, because in my understanding it contradicts it self:

a) host=<value> (or not setting it at all) is for active-passive
b) (the behavior until 21.04) is host=<same_value>.

host=<same_value> is when we want to cluster the cinder-volume services in the way that is not supported/recommended by upstream

If you are saying that we *should* be using host=<same_value> for purestorage <= Ussuri,>=Pike, this is incorrect in case of new deployments. For existing deployments sure something should be done to be able to maintain the existing config (host=<same_value>) so the flag doesn't flip and doesn't cause issues (mentioned below)

@Nobuto: that patch is good workaround to achieve a way to maintain the existing config for purestorage. I will further develop this in the other LP.
