title: AWS Aurora ALTER TABLE not working
body: <p>I'm trying to add a new column to a table that weighs about 20GB using:</p>
  
  <pre><code>ALTER TBLE ... ALGORYTHM = INPLACE
  </code></pre>
  
  <p>After about one hour of processing, the ALTER command fails and returns the following error without adding the column:</p>
  
  <pre><code>ERROR 1034 (HY000): Incorrect key file for table '[TABLE]'; try to repair it
  </code></pre>
  
  <p>Any idea why is this happening?</p>
