title: All shards failed
body: <p>I was working on elastic search and it was working perfectly. Today I just restarted my remote server (Ubuntu). Now I am searching in my indexes, it is giving me this error.</p>
  
  <pre><code>{"error":"SearchPhaseExecutionException[Failed to execute phase [query_fetch], all shards failed]","status":503}
  </code></pre>
  
  <p>I also checked the health. The status is red. Can anyone tell me what's the issue. </p>
