  <p>How to find out why it does not start? Other nodes now in "pending" status.  </p>
  
  <p>PS Maybe "node name already occupied couchbase babysitter_of_ns_1" is the second attempt to start, and main error is "Disallowed KILL_REQ, live nodes"</p>
  
  <p>PPS In general, the node on the other nodes in the cluster is shown as down, other nodes in "pend" state, and the port 8091 on broken node does not respond, although after the start of something started.</p>
