Hi

Check out the two last comments for HDFS-1312 :
https://issues.apache.org/jira/browse/HDFS-1312

If you can't afford to wipe out DN data and rebalance, you can try out=20
the proposed script (after non-prod testing obviously)

      <br>
      <br>
      I need to free some space on one of the data directories on one
      server.
      <br>
      I have 2 data volumes : /data/1 and /data/2
      <br>
      <br>
      One of the hard drives was broken, and after we replaced it, i ran
      a rebalance.
      <br>
      The problem is i forgot to change the policy to FreeSpace (insted
      of default round-robin).
      <br>
      <br>
      So now i have only 60MB free on /data/1 , and this is where
      checkpoints are stored.
      <br>
      <br>
      So i need an advice how can i free some space only on this volume.
      <br>
      <br>
      Can i just delete something from
      <br>
/data/1/dfs/dn/current/BP-1312742174-xxxxx-1359718879114/current/finalize=
