Hello all,

A DRBD integration into oVirt is currently being planned.

DRBD provides replicated, highly available block storage. For those unfamiliar with DRBD more information can be found here: https://www.drbd.org/en/comp/drbd-linux-driver

DRBD 9 is the latest version of DRBD and interacts with DRBD Manage which is a daemon exposed via a D-Bus api. More information can be found here: https://www.drbd.org/en/comp/drbdmanage

DRBD Manage handles the creation, assignment, etc. of DRBD volumes and is the interface through which Cinder manages DRBD.

We are looking for advice on how best to have oVirt communicate with DRBD Manage and we have come to two options:

1) Use Cinder. Although we are integrated into Cinder, there are concerns about the need to set up a complete Cinder instance to provide access to DRBD.

2) The alternative to Cinder would be to have the oVirt Engine communicate directly to DRBD Manage via D-Bus.

Any advice on the best way to achieve this would be much appreciated.
