Subject [jira] [Created] (HDFS-1848) Datanodes should shutdown when a critical volume fails
Date Wed, 20 Apr 2011 00:02:05 GMT
Datanodes should shutdown when a critical volume fails
------------------------------------------------------

                 Key: HDFS-1848
                 URL: https://issues.apache.org/jira/browse/HDFS-1848
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: data-node
            Reporter: Eli Collins
             Fix For: 0.23.0


A DN should shutdown when a critical volume (eg the volume that hosts the OS, logs, pid, tmp
dir etc.) fails. The admin should be able to specify which volumes are critical, eg they might
specify the volume that lives on the boot disk. A failure in one of these volumes would not
be subject to the threshold (HDFS-1161) or result in host decommissioning (HDFS-1847) as the
decommissioning process would likely fail.
