I've been working a similar setup with 2 nodes and a quorem
server and have not had much success. I'm moving on to drbd9 as
the three active node setup looks appealing, however, for some
reason not communicated to me, the moderators blocked (or didnt
process) my last submission to drbd-user. If I have any success,
I'll post it, assuming its not blocked again.<br>
(no,I was not foul mouthed or unprofessional)<br>

<div>Hi, <br>
<br>
</div>
I've been using drbd for a few months now and I am far
from an expert. So please excuse me for any stupid
question.<br>
<br>
</div>
I have the following task: <br>
- Cluster of 3 nodes(Node1 and Node2 - main nodes, Node3 -
backup node). I know I should use Stacked devices. <br>
- Managed by Pacemaker(version 1.1.8). <br>
- Drbd(version 8.3) replication between the 3 nodes. <br>
- Node3 is backup. It should stay slave until both Node1 and
Node2 are down. In this case, Node3 should be able to bring
up all the resources automatically. Once Node1 and/or Node2
are up, Node3 should pass the resources back to them.</div>
<br>
</div>
<div>
<div>I searched the web, did lots of setups and tests with the
existing drbd resource agent. No success. It seems that the
default drbd RA is unable to handle this configuration.<br>
</div>
<div>So I decided to extend it for my particular case. I did
this and succeeded, but the setup seems heavy, complex and
difficult to track. And sometimes crashes.<br>
</div>
<div><br>
I don't mind discussing my setup. <br>
But for now I'd like to ask this:<br>
</div>
<div>- Have you approached such configuration before? Did you
come up with solution?<br>
</div>
<div>- Is there working configuration for such setup? I mean
using the existing drbd resource agent<br>
</div>
<div>- Can I ask for an example? Guidelines?<br>
</div>
<div><br>
</div>
<div>Thanks in advance.<br>
</div>
<div>Greetings, Nedelin.<br>
