          From https://issues.apache.org/jira/browse/WHIRR-101?focusedCommentId=12917410&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12917410

          When we address this holistically, we may need to have a script that arranges the fstab and formats volumes accordingly, possibly using lvm or something to span disks together.

          Hadoop works best when disks aren't spanned together, since a datanode round robins between disks itself.
