Just looking at this again - after a numerous false starts.
In say a 4 node cluster with replicated I get the idea that each vdi would be stored on two nodes. But; you still have full mobility across the entire cluster - I assume that the actual vdi file will not move between nodes and as such will be using the network back to it's 'home' location.
Is there any way to find out in such a situation where the vdi actually physically lives, so the VMs can be arranged accordingly and to minimise problems caused my a sometimes flaky network.
Is it physically possible to move the location of a vdi within the xosan setup?
Can we have a dedicated XOSAN forum here?!
