I added tests for FrameRelayStorageStrategy and HostFileSystemStorageStrategy:

1.6-testing rev. 15256.
merged into trunk on rev. 15257.

I'm agree about the changes on datacollection-config.xml. What if we let
hrStorageIndex to use IndexStorageStrategy by default and write a comment about
the new HostFileSystemStorageStrategy ?

Something like this:

<resourceType name="hrStorageIndex" label="Storage (MIB-2 Host Resources)"
       resourceLabel="${hrStorageDescr} (index ${index})">
   <persistenceSelectorStrategy
class="org.opennms.netmgt.collectd.PersistAllSelectorStrategy"/>
   <storageStrategy
class="org.opennms.netmgt.dao.support.IndexStorageStrategy"/>
   <!--
   There is a new strategy called HostFileSystemStorageStrategy, that use file
system names as
   a resource index. The rules include to convert root filesystem (i.e. "/"
without quotes) to _root_fs,
   and for other file systems replace character "/" with "-".

   If you want to use this, replace strategy tag with this:
   <storageStrategy
class="org.opennms.netmgt.dao.support.HostFileSystemStorageStrategy"/>

   Remember that if you already have RRDs/JRBs... you will lost data.
  -->
</resourceType>
