DRDB yes. see: http://www.cloudera.com/blog/2009/07/22/hadoop-ha-configuration/ Really, when the question is DRBD + ZEN +"software X" the answer is always YES. Maybe on the high,high end issues like disk activity exceeding the ethernet capacity can be an issue, but for HDFS namenode you should be fine. (This problem would likely only occur with a very active disk like a database.) Edward
