Hi,

                The datanode process shutdown abnormally, 

                I set dfs.datanode.failed.volumes.tolerated =2 in
hdfs-site.xml.

                Because I found one disk is fail to access. 

                Then restart the datanode process, it works.

 

                One day later, we replace a good harddisk , and create
folder and chown to hadoop.

                Then I want to know if I don't restart datanode process,
when the datanode can know that 

                The disk is good now?

                May I have to restart datanode process to update this?

                

Env:Hadoop 2.6

 

 

Best Regards,

Evan
