title: removing leaf from memsql cluster leads to slave partitions
body: <p>After removing a leaf from the memsql cluster i ended up having 2 slave partitions that are blocking the functionality of my cluster right now.  </p>
  
  <p>ERROR 1777 (HY000) at line 1: Partition &lt;>:&lt;> has no master instance.</p>
  
  <p>I was reading that slave partitions can appear only in replication - 2 , however i have replication -1 .</p>
  
  <p>Also what is the step to follow from here? Promoting partition does not work .</p>
