> When a disk fails, the startup script executed by ambari will prevent the node
> from starting due to an mkdir type operation on all directories. If the disk
> is RO, the datanode will not use it, and if failed volumes is greater than 1,
> it's valid to start a datanode in this case. Ambari won't let us.
