Re: [Gluster-users] initial pool setup -- bidirectional probe required?
Hi Atin, 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.

Re: [Gluster-users] initial pool setup -- bidirectional probe required?
You'd not need a bidirectional probe until and unless you want to assign multiple IPs/host names to a particular peer.

[Gluster-users] initial pool setup -- bidirectional probe required?
All: According to the docs, when you initially set up a gluster storage pool, the first two servers need to probe each other. However, after that, you add additional servers in by probing from a node that's already in the pool. However, when I follow the directions with gluster 3.8, the behavior doesn't seem to match up when I do the initial set up of two nodes. 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. In addition, if I do a probe from server 2 to server 1, it does not just say probe success. Instead it says, "probe successful host already in peer list". So here are my questions: is this initial probe each server from the other dance actually required? And if it is, is a there a way to tell through a command or looking at a log whether that's occurred or not? https://gluster.readthedocs.io/en/latest/Administrator%20Guide/Storage%20Pools/ Thanks, Joe ___ Gluster-users mailing list Gluster-users@gluster.org http://lists.gluster.org/mailman/listinfo/gluster-users
