Hi Allon,<br>
<br>
A DRBD Storage Domain in oVirt is the goal, yes.<br>

Hello all,<br>
<br>
A DRBD integration into oVirt is currently being planned.<br>
<br>
DRBD provides replicated, highly available block storage. For those<br>
unfamiliar with DRBD more information can be found here:<br>
<a href="https://www.drbd.org/en/comp/drbd-linux-driver" rel="noreferrer" target="_blank">https://www.drbd.org/en/comp/drbd-linux-driver</a><br>
<br>
DRBD 9 is the latest version of DRBD and interacts with DRBD Manage which<br>
is a daemon exposed via a D-Bus api. More information can be found here:<br>
<a href="https://www.drbd.org/en/comp/drbdmanage" rel="noreferrer" target="_blank">https://www.drbd.org/en/comp/drbdmanage</a><br>
<br>
DRBD Manage handles the creation, assignment, etc. of DRBD volumes and is<br>
the interface through which Cinder manages DRBD.<br>
<br>
We are looking for advice on how best to have oVirt communicate with DRBD<br>
Manage and we have come to two options:<br>
<br>
1) Use Cinder. Although we are integrated into Cinder, there are concerns<br>
about the need to set up a complete Cinder instance to provide access to<br>
DRBD.<br>
<br>
2) The alternative to Cinder would be to have the oVirt Engine communicate<br>
directly to DRBD Manage via D-Bus.<br>
<br>
Any advice on the best way to achieve this would be much appreciated.<br>
<br>
