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
