Hi Edward

I have asked questions in the last weeks about implementation of NAS 
boxes and host vserver machines.

What does AFR stand for ?


I would like to be able to run guests which have web servers, databases, 
mail servers and other systems all remotely mounted from 2 NAS servers.

I wanted to have the data mirrored between the two NAS's.

GlusterFS would seem to do all the above but because its a userland file 
system it would be fair to ask questions about its performance.

Where you able to do any performance for large and small files ?

Mike
