I configured with afr option, but when I created, modified or delete a file
on server2, don´t replicate on other server and client. Replicated between
server1 and client.
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
What I do wrong?
