[Gluster-devel] replicate data between 2 servers and 1 client

[Alain Gonzalez]

I changed vol files, because I need data replicated on three machine (two
servers and one client). If I changed data on 1 machine, data must be
changed on the other two machines...

My actual vol file:

Server1:

volume brick
 type storage/posix
 option directory /home/export/
end-volume


### Add network serving capability to above brick.
volume server
 type protocol/server
 option transport-type tcp
 subvolumes brick
 option auth.addr.brick.allow * # Allow access to "brick" volume
end-volume

Server2

volume brick
 type storage/posix
 option directory /home/export/
end-volume

### Add network serving capability to above brick.
volume server
 type protocol/server
 option transport-type tcp
 subvolumes brick
 option auth.addr.brick.allow * # Allow access to "brick" volume
end-volume

Client:

### Add client feature and attach to remote subvolume of server1
volume brick1
 type protocol/client
 option transport-type tcp
 option remote-host 192.168.240.227      # IP address of the remote brick
 option remote-subvolume brick           # name of the remote volume
end-volume

### Add client feature and attach to remote subvolume of server2
volume brick2
 type protocol/client
 option transport-type tcp
 option remote-host 192.168.240.228      # IP address of the remote brick
 option remote-subvolume brick           # name of the remote volume
end-volume

volume afr
 type cluster/afr
 subvolumes brick1 brick2
end-volume

Raghavendra G said me that in Glusterfs 2.0 requires posix-locks. I proved
changed "type storage/posix" for "type features/posix-locks" but not working
correctly.
