> Prior to HDFS-1826, doUpgrade() would fail if any of the storage directories failed to
successfully write the new fsimage or edits files.
> Now it appears to "succeed" even if some or all of the individual directories fail.
> There is some discussion about whether doUpgrade() should have some fault tolerance,
but for now make it fail on any single storage directory failure, as before.
