Alternatively we could start cluster2 daemon before split-brain test

Assuming this change would re-introduce a race on the local environment? If so and if possible, might be easier to just start the second daemon before the test case.

I believe the error "image is still primary within a remote cluster" is possible only when the second daemon is started? As I understand it is triggered when the tag owner is not ORPHAN_MIRROR_UUID.
It is set to ORPHAN_MIRROR_UUID by demote request and can be changed only if mirroring is started?

I assume we are testing a bit different cases when running rbd_mirror.sh with RBD_MIRROR_USE_RBD_MIRROR set (daemons are not stopped/started, theuthology case) and when it is not set. If we force the second daemon to start, the cases will became the same. There is good and bad things with this.

I am slightly in favor of my current version though.
