server.vol :

type storage/posix # POSIX FS translator
option directory /media/storage # Export this directory
end-volume
volume posix-locks-home1
type features/posix-locks
option mandatory-locks on
subvolumes home1
end-volume
### Add network serving capability to above home.
volume server
type protocol/server
option transport-type tcp
subvolumes posix-locks-home1
option auth.addr.posix-locks-home1.allow * # Allow access to "home1" volume
end-volume
----------
client.vol:
---------
## Reference volume "home1" from remote server
volume home1
type protocol/client
option transport-type tcp/client
option remote-host 192.168.253.41 # IP address of remote host
option remote-subvolume posix-locks-home1 # use home1 on remote host
option transport-timeout 10 # value in seconds; it should
be set relatively low
end-volume
## Reference volume "home2" from remote server
volume home2
type protocol/client
option transport-type tcp/client
option remote-host 192.168.253.42 # IP address of remote host
option remote-subvolume posix-locks-home1 # use home1 on remote host
option transport-timeout 10 # value in seconds; it should
be set relatively low
end-volume
volume home
type cluster/afr
option metadata-self-heal on
subvolumes home1 home2
end-volume
--------
Make sure the IP addresses are correct.
You can use the same server.vol and client.vol for both the machines.
(assuming you have backend directory names same)
