将新的硬盘加入hdfs-site.xml配置中吧:
dfs.data.dir
${hadoop.tmp.dir}/dfs/data
Determines where on the local filesystem an DFS data node
should store its blocks. If this is a
[color=]comma-delimited
list of directories, then data will be stored in all named
directories, typically on different devices.
Directories that do not exist are ignored.
