Hi & thanks,

Well, obviously my intention is not to create a mess, but the reason for 
redundancy is probably that servers may disappear from the cluster for a 
while. In case I run any glusterfs commands related to the volume 
definition at that time, those changes will not reach the unavailable 
server. That's why I wonder how GlusterFS will sync such information 
when the server is available again? In case I know how that is handled, 
I'll know what I can do and what I cannot do.
