Hi everyone, As everyone hopefully knows by now, improving the peer identification mechanism within Glusterd is one of the features being targeted for glusterfs-3.6. [0] I had proposed this a while back, but had not been able to do much work related to this till now. Varun (CCd) and I have been working on this since last week, and are hoping to get at least the base framework ready and merged into 3.6. The main problem we have currently is that a peer can be associated with just a single address. This is stored in peerinfo->hostname. This isn't sufficient to address all possible addresses a peer could be associated with and lead to failures identifying peers during various commands. Also our identification isn't able to correctly match shortname, fqdns and ips, which could also lead to failures. Varun and me are hoping to solve these two problems and are currently working towards it. We hope to do the following, 1. Extend peerinfo to hold a list of addresses instead of a single address. 2. Improve peer probe to add unknown addresses to this list when we identify that it belongs to a known peer 3. Improve glusterd_friend_by_hostname helper to correctly handle matching addresses. These 3 changes should lay down the base for improving glusterds peer identification problems. I've updated the feature page [0] with the latest details. We have been doing changes over the past week, and our changes can be viewed on my glusterfs forks on forge [1] and github [2]. We currently don't have any changeset for review on gerrit, but if anyone wants to review code right now, you can use [3].
