> 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.
