Cluster integrity has been disturbed
<p>I get this error on only one node on a 2-node cluster once every week. 
Here's the errors I got on the AMC:</p>

<p>Main error:</p>

<blockquote>
  <p>Cluster integrity has been disturbed</p>
</blockquote>

<p>Error for every set : </p>

<blockquote>
  <p>Mismatch in replication factor for namespace test as shown by nodes</p>
</blockquote>

<p>For information, the 2 nodes have <strong>the same aerospike.conf file</strong> with a replication factor of 2. 
Another thing that caught my attention is that, the whole cluster is not available while only one node is down (not visible), so I am questionning myself on the HA of Aerospike.</p>

<p>To solve this problem, I simply restart the node not visible.</p>

<p><a href="http://www.aerospike.com/docs/operations/troubleshoot/cluster/#cluster-size-change" rel="nofollow">On the aerospike documentation</a> it says :</p>

<blockquote>
  <p>This can be true if a set of nodes has split from the main cluster. (This is sometimes referred to as a split brain.) Generally, it is easiest to restart the “lost” node(s) to get it/them to rejoin the cluster.</p>

<p>But as this problem occurs every week, I would love to solve this once and for all :) </p>
