Hi Melvin,

The bug is not reproducible with  glusterfs--mainline--3.0--patch-903. Can you check whether it is possible to reproduce the issue?

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?
