I imagine the server config would look like:
volume local-brick
type storage/posix
option directory /mnt/local-brick
end-volume
volume remote-brick
type protocol/client
option transport-type tcp/client
option remote-host 10.2.10.100
option remote-subvolume other-local-brick
end-volume
volume afr1
type cluster/aft
subvolumes local-brick remote-brick
end-volume
That's all a guess though.
But then would all your clients all only connect to 1 server? kinda
seems like so i guess unless there is some round robin something or
other?
I dunno - the client could use unify and mount both servers' afr1.
I'm sure someone with more clue can say for sure :)
