<p class="yiv6406426161MsoNormal">I created the VDO volumes fine on the drbd devices, formatted them as xfs filesystems, created cluster filesystem resources, and the cluster us using them. But the cluster won’t fail over. Is there a VDO cluster RA out there somewhere already?

<p class="yiv6406426161MsoNormal">For DRBD there is enough info, so let's focus on VDO.</p>
<div id="yiv6406426161yMail_cursorElementTracker_1620961478467">
<p class="yiv6406426161MsoNormal">There is a systemd service that starts all VDOs on the system. You can create the VDO once drbs is open for writes and then you can create your own systemd '.service' file which can be used as a cluster resource.<br clear="none">
