----------------------------------
    Comment: was deleted

(was: Thanks a lot and do you have some suggestion if I want to balance data when add disks for the system ？
like:
 1. install an new kudu on all disks
 2. dump all data from the old one
 3. import all data to the new one
 4. uninstall the old one
is this the best way ?
