Or am I looking at it the wrong way and should I do it different? Mirroring is one approach, but here's another: One of the servers holds the data and nfs exports it to the other two. The webroot is on the mounted nfs filesystem. This also eliminates potential data synchronisation problems if you have different filesystems having overlapping/incompatible changes made to them. It lets you invest in one really resilient storage system instead of three possibly inferior ones. Peter.
