For what it's worth, I just updated some CentOS 7 servers from GlusterFS 3.12.1 to 3.12.4 and hit this bug. Did the patch make it into 3.12.4? I had to use Mike Hulsman's script to check the daemon port against the port in the volume's brick info, update the port, and restart glusterd on each node. Luckily I only have four servers! Hoping I don't have to do this every time I reboot!

Could you confirm this should have been fixed in 3.10.8? If so we'll test it for sure!
Fix should be part of 3.10.8 which is awaiting release announcement.

I just read it and very happy you found the issue. We really hope this will be fixed in the next 3.10.7 version!
3.10.7 - no I guess as the patch is still in review and 3.10.7 is getting tagged today. You’ll get this fix in 3.10.8.
PS: Wow nice all that c code and those "goto out" statements (not always considered clean but the best way often I think). Can remember the days I wrote kernel drivers myself in c :)

We (finally) figured out the root cause, Jo!Patch https://review.gluster.org/#/c/18579 posted upstream for review.

We use glusterfs 3.10.5 on Debian 9.
When we stop or restart the service, e.g.: service glusterfs-server restart
We see that the wrong port get's advertised afterwards. For example:
Before restart:

They try to reach it on the "new" port instead of the old one:[2017-09-21 08:33:25.225006] E [socket.c:2327:socket_connect_finish] 0-public-client-2: connection to 192.168.140.43:49154 failed (Connection refused); disconnecting socket[2017-09-21 08:33:29.226633] I [rpc-clnt.c:2000:rpc_clnt_reconfig] 0-public-client-2: changing port to 49154 (from 0)[2017-09-21 08:33:29.227490] E [socket.c:2327:socket_connect_finish] 0-public-client-2: connection to 192.168.140.43:49154 failed (Connection refused); disconnecting socket[2017-09-21 08:33:33.225849] I [rpc-clnt.c:2000:rpc_clnt_reconfig] 0-public-client-2: changing port to 49154 (from 0)[2017-09-21 08:33:33.236395] E [socket.c:2327:socket_connect_finish] 0-public-client-2: connection to 192.168.140.43:49154 failed (Connection refused); disconnecting socket[2017-09-21 08:33:37.225095] I [rpc-clnt.c:2000:rpc_clnt_reconfig] 0-public-client-2: changing port to 49154 (from 0)[2017-09-21 08:33:37.225628] E [socket.c:2327:socket_connect_finish] 0-public-client-2: connection to 192.168.140.43:49154 failed (Connection refused); disconnecting socket[2017-09-21 08:33:41.225805] I [rpc-clnt.c:2000:rpc_clnt_reconfig] 0-public-client-2: changing port to 49154 (from 0)[2017-09-21 08:33:41.226440] E [socket.c:2327:socket_connect_finish] 0-public-client-2: connection to 192.168.140.43:49154 failed (Connection refused); disconnecting socketSo they now try 49154 instead of the old 49152Is this also by design? We had a lot of issues because of this recently. We don't understand why it starts advertising a completely wrong port after stop/start.
