But when I am trying to mount the created gluster vol from an external machine it fails. In the log files of the client I can see that gluster is annoucing the bricks with the cloud infrastructure internal ips, which are not accessible from outside of the cloud. When I change the internal ips to the public domain names in /var/lib/glusterd/gv0.tcp-fuse.vol on every cluster host it works seamless. I definitely think that this is not the recommended way to solve this problem. Of course it breaks, if I add another bricks to the gluster.

I tried this first with negative result:

azureuser at stage1-gluster2:~$ sudo gluster peer probe stage1-gluster1.cloudapp.net
peer probe: failed: Error through RPC layer, retry again later

And in the log of the opposite:

[2015-07-24 08:51:03.223634] E [rpcsvc.c:617:rpcsvc_handle_rpc_call] 0-rpc-service: Request received from non-privileged port. Failing request

I didn’t set “server.allow-insecure”, because I think it is not a good idea. It is ok to use this in public and productive environment? I am also using ssl, do the “allow-insecure” setting has an impact on this security?
