Hi,

Not clear how this computation is done

For sake of discussion Say the machine with data node has two disks /disk1
and /disk2. And each of these disk has a directory for data node and a
directory for non-datanode usage.

/disk1/datanode
/disk1/non-datanode
/disk2/datanode
/disk2/non-datanode

The dfs.datanode.data.dir says "/disk1/datanode,/disk2/datanode".

With this, what does the DFS and NonDFS indicates? Does it indicates
SUM(/disk*/datanode) & SUM(/disk*/non-datanode) etc. resp. ?

Thanks,
