> Make DN minimum valid volumes configurable

> Key: HDFS-1161
> URL: https://issues.apache.org/jira/browse/HDFS-1161
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: data-node
> Affects Versions: 0.21.0, 0.22.0
> Reporter: Eli Collins
> Assignee: Eli Collins
> Fix For: 0.21.0, 0.22.0

> Attachments: hdfs-1161-1.patch, hdfs-1161-2.patch, hdfs-1161-3.patch,

>
>
> The minimum number of non-faulty volumes to keep the DN active is hard-coded
> to 1. It would be useful to allow users to configure this value so the DN
> can be taken offline when eg half of its disks fail, otherwise it doesn't get
> reported until it's down to it's final disk and suffering degraded
> performance.
