There was a problem hiding this comment.
clgtm(, I´d factor out some code to extra methods though, for readability)

Description
This changes the way how the linstor plugin sets the correct options to allow live-migration.
Before we set
allow-two-primariesoption on all resources and also don't enable protocol C for that brief time.Now we explicitly set
allow-two-primariesand protocol C on the specific resource connection used andafter the live migration is done those options get removed.
This allows live migration to work if you have set protocol A between 2 datacenters (e.g. DR site).

Live migration in a Linstor cluster with protocol C and A configured between nodes.
How did you try to break this feature and the system with this change?
