However you will need to rebuild the DRBD module against your new kernel if you haven't already.
There "shouldn't" be any compatibility issues running Xen and DRBD.

You can use DRBD, but using virtual guests serial cable between 2 VMWare hosts, and binding the DRBD clients to these physical interfaces this.
Can I use DRBD in a VMware guest?
Yes, you can.

The other way to test is to do a hard reboot on one.. .
Also you do not want to turn of drbd services .

I need to implement Linux-HA configuration in two servers. I've decided to use DRBD for block level replication on both hosts, mainly for MySQL data replication.
As I understand, in DRBD configuration there's always a primary server, others are slaves...

The slave does not mount the partition so working.
As far as I know, DRBD does partition level replication.
If you need DRBD "mainly" for MySQL replication, maybe it is easier to use the replication features.

Does anyone have experience configuring drbd with heartbeat between 2 virtual linux machines (VMWare Infrastructure)?
The problem I am running into is that heartbeat likes multiple data paths to see its peer node. For instance, it likes to have a network...

Finally - maybe DRBD is just not right....
Have you looked whether the VMs complain about API.
Not only does DRBD not use a serial cable, it can't ! I have no idea what you're talking about with this, DRBD has got nothing to do with it.

Is it possible to DRDB a entire server?
We have ~5 or so webservers that have identical specs but for each one I had to log in and install all the software, etc..
With DRDB I was thinking if I update one (say recompile apache), all of them would be updated...

As others have said, there is a limit to the number of nodes with DRBD.
For your automatic updates you boot with NFS root.
Hi,
this will not work, because drbd only supports three nodes.

sometimes, we loose connection between the two nodes (node 1 and node 2). When this happens, the two nodes starts both the services as masters,because they don...

I think you should first look at why the connection gets lost .
Hi and welcome to LinuxQuestions,
AFAIK that would take away the advantage of having high availability for your service .
