> Project: Hadoop HDFS
> Issue Type: Bug

> The description of dfs.datanode.disk.check.timeout in hdfs-default.xml is as
> follows:
> {code}
> <property>
> <name>dfs.datanode.disk.check.timeout</name>
> <value>10m</value>
> <description>
> Maximum allowed time for a disk check to complete during DataNode
> startup. If the check does not complete within this time interval
> then the disk is declared as failed. This setting supports
> multiple time unit suffixes as described in dfs.heartbeat.interval.
> If no suffix is specified then milliseconds is assumed.
> </description>
> </property>
> {code}
> I don't think the value of this config is used only during DataNode startup.
> I think it's used whenever checking volumes.
> The description is misleading so we need to correct it.
