Hi,
I really need some body help here. I try to make 3 servers, 2 as server, and 1 as a client. I want to use "cluster/unify". But when i try to run, it always tell not connected. But if i comment the "cluster/unify" configuration it come to connected. Is there a way to make the glusterfs only able to unify all resources storage from other server in one pool data server only ?
Let me shared my configuration here ;
Server 1 Configuration (glusterfsd.vol)
[root at fs-lb1 glusterfs]# cat glusterfsd.vol
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
volume brick
type storage/posix
option directory /data
end-volume
volume server
type protocol/server
option transport-type tcp
option transport.socket.bind-address 192.168.0.10 # Default is to listen on all interfaces
option transport.socket.listen-port 6996 # Default is 6996
option client-volume-filename /etc/glusterfs/glusterfs-client.vol
subvolumes brick
option auth.addr.brick.allow 192.168.0.* # Allow access to "brick" volume
end-volume
volume brick-ns
type storage/posix # POSIX FS translator
option directory /data/export-ns # Export this directory
end-volume
volume servers
type protocol/server
option transport-type tcp # For TCP/IP transport
option transport.socket.listen-port 6999 # Default is 6996
subvolumes brick-ns
option auth.addr.brick-ns.allow * # access to "brick" volume
end-volume
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Server 2 Configuration (glusterfsd.vol)
[root at fs1 glusterfs]# cat glusterfsd.vol
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
volume brick2
type storage/posix # POSIX FS translator
option directory /Data # Export this directory
end-volume
volume server
type protocol/server
option transport-type tcp
option transport.socket.bind-address 192.168.0.11 # Default is to listen on all interfaces
option transport.socket.listen-port 6996 # Default is 6996
subvolumes brick2
option auth.addr.brick2.allow * # Allow access to "brick" volume
end-volume
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Client Configuration (glusterfs.vol);
[root at appman glusterfs]# cat glusterfs.vol
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

option remote-host 192.168.0.10 # IP address of the remote brick
option remote-subvolume brick # name of the remote volume
end-volume
volume client2
type protocol/client
option transport-type tcp
option remote-host 192.168.0.11
option remote-subvolume brick2

option remote-host 192.168.0.10 # IP address of the remote brick
option transport.socket.remote-port 6999 # default server port is 6996
option remote-subvolume brick-ns # name of the remote volume
end-volume
volume unify

I try to run with debug mode, i get the ouput here ( I don't know how to understand the output here) ;

Please help me out how to do the unify the storage to be a pool storage. Please correct my configuration. Is there a mistake on that ?
First of all, thank you very much for your kindly response.
