If all your AFR ad Unify translators are defined on the server side, you
have to have some form of failover on the client, such as a round-robin
IP address between the servers, or heartbeat for a shared IP, etc.
If you put unify on the client side, or both unify and AFR on the client
side, nothing else should be required. I would advise you to set the
transport timeout to something smaller though,even if it's just for
testing purposes and you set it higher again later. I find 10 seconds
works fine for me.

OK => If I unplug ethernet eth0, /mnt/glusterfs is no responding until I plug again the ethernet eth0
I didn't configure transport timeout and if don't plug again ethernet eth0, /mnt/glusterfs is no responding ...What is the time-period before command complete successfully because I have waiting about 30 secondes !
Have I to necessarily to configure transport timeout ?
When you say "But after that time-period command should complete successfully", is condition to plug again ethernet eth0 ?
If you want say that command should complete successfully after a time-period slightly greater than transport timeout without to plug again ethernet eth0 (server), have I to use necessarily translator unify with "rr" in first before translator AFR, or is translator AFR alone does automatically high availability if one sublvolume is down ?
PS: I have only 2 nodes server for my test.
Should I have 3 nodes server to have high availability if I use AFR with option replicate *:2 or should I have high availability too if I have 2 nodes server with AFR with option replicate *:2 if I unplug ethernet eth0 server ?

Hi Benjamin,
It may not be responsive for a period slightly greater than transport
timeout. But after that time-period command should complete successfully.

Yet I use unify rr + AFR between server A and server B
Is it normal for a high availability storage system like glusterfs ?
