<p class="MsoNormal">My main motivation is the desire for a compressed filesystem. I have experimented with using VDO for that purpose and it works, but the setup is complex and I don’t know if I trust it to work well when VDO is in a stack of Pacemaker cluster
resources. If there a better way of getting compression to work above DRBD?<o:p></o:p></p>
