title: How can orientdb create a index at the same time can accept written
body: <p>I'm sorry I ask agin. If I can't solve, orientdb can't put into production. </p>
  
  <p>My orientdb server version is 2.1.11, woking in distribute mode.</p>
  
  <p>I find when I create a index, all the node can't be written, request clients occurred "Quorum x not reached for request".</p>
  
  <p>How can orientdb create a index at the same time can accept written, rather than lock the cluster (all nodes).</p>
