Hello,
i'm new to DRBD and have some problems with splitbrains every week or so.
I have a standard Active/Passive setup as given in the
drbd-documentation and this is my config file:

usage-count no;
}

syncer { rate 100M; }
protocol C;
}

I have a two node cluster setup with Pacemaker and DRBD to run Postgres.
For whatever reason, drbd is almost always in an inconsistent state
everyday multiple times a day doing a big sync. Why is this happening?
Both nodes are Ubuntu 10.04.1 running drbd 8.3.7-1ubuntu2.1.

Yes. And every DRBD device on his own LV. Same thing on the second node.

This issue was reported to DRBD list and Citrix forums 2 weeks ago.
There was no official follow up from neither of the vendors.
Seems it's a Xen new kernel issue which was resolved internally at Citrix,
but fix is not available at present time. See thread below:

Hi there,
yesterday I did a regular manual fail-over (swap-over) to the second node of a
primary/slave drbd cluster.
This is the haresources:

I'm in this situation: Host A has a DRBD resource (primary, StandAlone)
and I want to create a diskless peer for it in dual-primary setup on
host B. So I do the following:

--create-device

Hi guys,
This is another report of DRBD not working with Xenserver 5.6 FP1. I
