---------------------------------------

             Summary: Make sure a disk goes R/O for datanodes the datanodes are still started.
                 Key: AMBARI-5358
                 URL: https://issues.apache.org/jira/browse/AMBARI-5358
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 1.5.1


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.
