Re: [Xen-users] Distributed xen or cluster?

[Rob Beglinger <rbeglinger@xxxxxxxxx>]

Nick,

Is your SAN an Active-Active or Active-Passive SAN?  I'm looking to set something up like what you're doing, but my SAN only supports Active-Passive.  We originally looked at Win2K8 with Hyper-V but fortunately that requires a SAN that supports Active-Active configuration.  I'm using SLES 10 SP2 for dom0, and will be running SLES 10 SP2 domU's as well.  I am running Xen 3.2.

I use SLES10 SP2 for my dom0, which has a few tools that make this possible:

- EVMS + Heartbeat for shared block devices

- OCFS2 for a clustered filesystem

- Heartbeat for maintaining availability.

 

I have a volume shared out from my SAN that's managed with EVMS on each of my Xen servers.  I created an OCFS2 filesystem on this volume and have it mounted on all of them.  This way I do file-based disks for all of my domUs and they are all visible to each of my hosts.  I can migrate the domUs from host to host.  I'm in the process of getting Heartbeat setup to manage my domUs - Heartbeat can be configured to migrate VMs or restart them if one of the hosts fails.

 

It isn't a "single-click" solution - it takes a little work to get everything running, but it does work.

Anyone aware of any clustering package for xen, in order to gain redundancy, etc.
