I'm looking at high availability webserver setups at the moment and wondered if anyone was running a clustering filesystem across multiple Bitfolk VPSes?

I've been doing some reading on GlusterFS and it would seem to do what I need it to. I'm going to have a play with it on a couple of local VMs first while I understand how to make it work in my setup, but just wondered if anyone else is doing similar or has any words of wisdom?

Thanks

Alex
