Data node down

[#1]

Hi,

Assume that, I have 4 hard disk in my data node, if any one hard disk fails; my data node will go down.

Now my question is, what parameter I have to setup to avoid my data should be up?

Thanks in advance.

Sorry, my question is what parameter do I need to set, to avoid going down my data node

Set the "DataNode Failed Volumes Tolerated" field in CM -> HDFS ->
Configuration to the number of volumes each DN should tolerate the failure
up to. XML property, if you do not use CM, is
"dfs.datanode.failed.volumes.tolerated".
