Auto-promote is enabled. As you can see it failed, and it can only fail
if it was enabled... Your problem is the "multiple primaries" thingy.
Please tell us which drbdmanage commands you executed. The granularity
of "trying to live migrate" is a bit too coarse to reproduce the issue.
At least for me.
