Krishna,

I am trying to figure out a config that will give me 4+ servers in  
cluster/unify and with replicate *:2 on AFR. Here is my config  
without iothreads,writebehind, etc... I modeled this after http:// 
www.gluster.org/docs/index.php/ 
GlusterFS_User_Guide#AFR_Example_in_Clustered_Mode

What am I doing wrong? Can you fix my example?  I want to scale to 20  
nodes also, what do I need to change to get to 20 nodes?


### NODE 1 server.vol
volume brick
         type storage/posix
         option directory /var/GlusterFS
end-volume

volume brick-afr
         type storage/posix
         option directory /var/GlusterFS-AFR
end-volume

volume server
         type protocol/server
         option transport-type tcp/server
         option bind-address 172.16.30.11
         option listen-port 6996
         subvolumes brick brick-afr
         option auth.ip.brick.allow 172.16.30.*
         option auth.ip.brick-afr.allow 172.16.30.*
end-volume


### NODES 2-4 server.vol
same as above but with 172.16.30.12 bound
