I'm considering setting up a Lustre cluster system for our XEN virtual machines as shared storage, mainly for high availability on our XEN VPS servers.
Does anyone use Lustre in a production environment? What is your opinions / experiences with it?
I haven't used Lustre but was also researching on using it for same purpose as shared storage for VMs. Dropped it in the end from consideration after some discussion on the Lustre mailing list points out that it's more intended for high performance rather than high availability. So it might not be that suitable as a HA solution.
Have you considered trying Gluster instead? _______________________________________________
Well, I'm really after the speed it offers.
With lustre, from what I understand, I could use say 3 or 5 or 50 servers to spread the load across the server and thus have higher IO. We mainly host shared hosting clients, who often have hundreds & thousands of files in one account. So if their files were "scattered" across multiple servers then the access to those files would be quicker.
In terms of high availability, I'm thinking that if I use more servers and thus have less load on each server, then the rate of failure would also be less. I see they have a high availability option, but would also be interested to know what was said about it. Would you can to point me to the specific conversation about this?
