Hi Melvin,

Can you send the volume specification files of two servers? Are the two afrs in server configuration have children in the same order?

regards,

Hi,

I've tried setting up the HA translator using glusterfs-2.0.0rc1 and fuse-2.7.4glfs11. I have a 2 clients connecting to the 2 glusterfs-servers (lb1 and lb2) which run server-side AFR between themselves. To test if the HA works, I shutdown the lb1. I could see both the clients switching to lb2 in the log (fuse-bridge: inode num of /globalshare changed 54394886 -> 30605318) so it works fine. However when I restarted lb1 and try to shutdown lb2, 1 of the clients report "Transport endpoint is not connected" and the logs are as below. Can someone advise if HA translator is currently stable?
