Resolving a split brain on replication

[Gr-R]

make sure nodes can ping each other.

clear metadata on both nodes, and verify source/destination settings.

reestablish connections and then the add the task.

I've already done this. The nodes can see each other plainly. I've practically redone the configuration from scratch and the result is always the same.
We have also replicating from the secondary node to the first node.

[Gr-R]

check and make sure NIC settings are same on both nodes... jumbo frames ?

also make sure volumes are same size.

have you done anything to tune drdb ? same settings on both nodes ?

[enealDC]

Keep in mind that as I've already said, I have completely restored factory configuration and setup. Removed contents of units, etc. These units are on the same vlan and when you configure replication, you can see the volume on the other end indicating good connectivity. In addition, the task gets created on the remote node..
As I said previously, it does not appear that this error or situation is resolvable via any of the interfaces I have at my disposal..

send me the logs from each node, via support, or in PM

[enealDC]

sent to support@open-e.com

there are sock errors on the network connection between the nodes.

reset the DRDB configuration to default and see if it works

default values:
max-buffers=2048
max-epoch-size=2048
unplug-watermark=128
sndbuf-size=0
al-extents=127
no-disk-barrier=off
no-disk-flushes=off

Thanks for looking it over.
We started with the defaults and modified it as a last resort to see if it would fix it.
In short, we've already tried reestablishing it using the default settings..
