thanks for your reply. I am trying to understand what you mean. for
instance, I have 6 clients and 3 GFS servers, they are divided into 3
client1 GFS server1
client3 GFS server2
client 5 GFS server3
So my question is how to balance the workload between these 3 GFS
servers since they are hosting identical data?
anyone successfully implemented this using CTDB+GFS?
