To help this fellow along, I will translate his post:

Hello,

I would like to implement a cluster with Xen or Xen server with two Dell
R710 servers.

I would like to build a cluster using the entire added diskspace of the
two
servers, as well as the total memory.

What are your experiences and configurations for this?

Thanks in advance,

Regards,

Mat



Well Mat,

I usually use DRBD and Pacemaker for this. You can load balance the
cluster
resources (being Xen DomU's) across the two nodes. For live migration you
need dual primary.
For dual primary you need stonith.

I'm not familiar (yet) with Cloudstack, but
http://cloudstack.org/cloudstack/requirements.html seems to state that
the requirements are more than two servers. I guess this solution won't
do Mat a lot of good, does it?

cheers,

You're right. To get useful benefits from using cloudstack, one would need
*at least* one gateway/firewall,
one management node, a primary storage (local, redundant like drbd
master/master are not supported
out of the box and need to be "hacked"), one secondary storage (nfs e.g.)
and at least one switch capable
of dynamic vlan registration (i forget, 802.something).
Personally, I love cloudstack, but for the OP's needs, drbd master/master
with a stonith (could be done via
IPMI / iDRAC) would be a much better solution. For a two node cluster, i
think, REMUS and/or Kemari projects
are worth a try for failover scenarios.




I'm actually having the same challenge as OP. What if you would run
cloudstack ON a drbd master/master as a series of virtual machines? The main
benefit would be easy provisioning, central management, snapshotting etc

Well at that point just throw XCP into the mix...... itll run from local disk
Was thinking about that,

thx!
