[Gluster-users] gluster probe node by hostname

[可樂我]

Thanks for your answer!
I am using glusterfs-3.6 and I know the situation you talk about.
I will see the 'Other Names' when I reverse probe node.

I still see the hostname and ip peer status when I restart GlusterD of
Node3 after modify peer file in Node3
But I don't want to see the any ip in peer status, how can I do?
Thank you very much
