---------------------------------

             Summary: Use ERROR instead of INFO for volume failure logs
                 Key: HDFS-4048
                 URL: https://issues.apache.org/jira/browse/HDFS-4048
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.0.0-alpha
            Reporter: Stephen Chu
            Assignee: Stephen Chu
             Fix For: 3.0.0, 2.0.3-alpha


I misconfigured the permissions of the DataNode data directories (they were owned by root, instead of hdfs).

I wasn't aware of this misconfiguration until a few days later. I usually search through the logs for WARN and ERROR but didn't find messages at these levels that indicated volume failure.

After more carefully reading the logs, I found:
{code}
2012-10-01 13:07:10,440 INFO org.apache.hadoop.hdfs.server.common.Storage: Cannot access storage directory /data/4/dfs/dn
2012-10-01 13:07:10,440 INFO org.apache.hadoop.hdfs.server.common.Storage: Storage directory /data/4/dfs/dn does not exist.
{code}

I think we should bump the log level to ERROR. This will make the problem more visible to users.
