Hi
  Can anyone tell me the correct procedure to replace a hard disk in slave node (running datanode and region server) that indicate it might fail (red light in the HD) soon ? Thanks in advance.

1.) Shutdown rs
2.) Shut down dn
3.) Shut down server
4.) Replace drive
5.) Start server
6.) Services should start automatically
7.) Profit
