title: redshift leader node using up 100% of disk
body: <p><a href="https://i.stack.imgur.com/E9iJ8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/E9iJ8.png" alt="enter image description here"></a>we have a 50 node redshift cluster, and we run vacuum periodically. and currently we are running a pipeline where we are moving some data onto S3 and deleting it from redshift.</p>
  
  <p>after about 2 weeks of processing. our disk usage on 49 nodes ( except leader ) came down from 95% to 80%. but the disk usage on leader went up and its now at 100%.</p>
  
  <p>I tried rebooting the cluster to see if there were transient files that were holding the space. but that didnt help.</p>
  
  <p>any suggestion would be a great help at this point.</p>
  
  <p>thanks!</p>
