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. Read up on http://www.clusterlabs.org B.

I guess this solution won't do Mat a lot of good, does it? cheers, B. 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. _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

Thanks for all your answers I think that am going to test to configure my cluster by using DRBD and Pacemaker On the other hand DRBD is good to use two servers but it is not suited for more servers.

Gluster is supposed to scale well with many servers. Not sure if it can replace drbd though.

If you need to deploy more than tool XCP or XenServer servers per pool, then you need to use a shared iSCSI or NFS target instead of DRDB. I recommend building something ZFS based using Nexenta, OpenSolaris, or OpenIndiana. We experimented with Gluster, but we could never get the performance out of it that we could easily get from ZFS based solutions. We also played with FreeNAS and OpenFiler, but neither of those could match the performance of Nexenta/OpenSolaris/OpenIndiana. Here is a good article about building a ZFS based storage solution, which can be used as either an iSCSI or NFS target. http://www.anandtech.com/show/3963/zfs-building-testing-and-benchmarking You could build the exact box shown in that AnandTech article and then toss Nexenta Community Edition on it for free. It would provide you with a fast, reliable iSCSI/NFS target for your Xen pools. Good luck. -----Original Message----- From: xen-users-bounces@lists.xen.org [mailto:xen-users-bounces@lists.xen.org] On Behalf Of Matthieu Roudon Sent: Wednesday, March 07, 2012 9:24 AM To: Bart Coninckx Cc: xen-users@lists.xen.org Subject: Re: [Xen-users] Cluster xen Thanks for all your answers I think that am going to test to configure my cluster by using DRBD and Pacemaker On the other hand DRBD is good to use two servers but it is not suited for more servers.
