<div dir="ltr">Hi Atin,<div><br></div><div>That's quite interesting. Why does a system with multiple ips make that necessary? Would you be able to provide an explanation on what the probe is actually doing and what it is used for? Or alternatively point me to some documentation that lays this out? Gluster official docs don't seem to really explore this in any detail from what I could find.</div><div><br></div><div>Thanks,</div><div>Joe</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Feb 4, 2017 at 4:29 AM, Atin Mukherjee <span dir="ltr"><<a href="mailto:atin.mukherjee83@gmail.com" target="_blank">atin.mukherjee83@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div>You'd not need a bidirectional probe until and unless you want to assign multiple IPs/host names to a particular peer.</div><div><br><div class="gmail_quote"><div><div class="h5"><div>On Fri, 3 Feb 2017 at 16:35, Joseph Lorenzini <<a href="mailto:jaloren@gmail.com" target="_blank">jaloren@gmail.com</a>> wrote:<br></div></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div class="m_8682467261790239266gmail_msg"><div class="m_8682467261790239266gmail_msg">All:</div><div class="m_8682467261790239266gmail_msg"><br class="m_8682467261790239266gmail_msg"></div><div class="m_8682467261790239266gmail_msg">According to the docs, when you initially set up a gluster storage pool, the first two servers need to probe each other.

I probe from server 1 to server 2 but I do not probe from server 2 to server 1. My expectation would be that either the pool or peer commands would indicate the server 2 does not "trust" server 1 but it in fact server 2 just indicates its successfully connected in a pool and server 1 is a trusted peer.</div><div class="m_8682467261790239266gmail_msg"><br class="m_8682467261790239266gmail_msg"></div><div class="m_8682467261790239266gmail_msg">In addition, if I do a probe from server 2 to server 1, it does not just say probe success.
