Have gluster events setup with two nodes 2. Do peer probe operation 3. Check the event message generated by the peer probe command Actual results: =============== UUID is showing zeros in the event message for the peer probe operation. Expected results: ================= It should show correct UUID in the event message.

However the subesquent (dis)connect events would be carrying the valid UUIDs. The way to solve this issue is to conditionally populate UUIDs. If EVENT_PEER_CONNECT has to be generated for the first RPC_CLNT_CONNECT which is because of a peer probe trigger the event would only have hostname whereas for the rest of the other cases the event will populate uuid along with hostname.

I got a suggestion in the patch saying let's not generate EVENT_PEER_CONNECT for a peer probe trigger which sounds right to me.

COMMIT: http://review.gluster.org/15678 committed in master by Atin Mukherjee (amukherj) ------ commit 9565222c3bb17d124e3d62ec0ab987ce45999047 Author: Atin Mukherjee <amukherj> Date: Wed Oct 19 12:53:35 2016 +0530 glusterd: conditionally pass uuid for EVENT_PEER_CONNECT When a new node is probed, on the first RPC_CLNT_CONNECT peerctx->uuid is set to NULL as the same is yet to be populated. However the subesquent (dis)connect events would be carrying the valid UUIDs. Solution is not to generate EVENT_PEER_CONNECT on a peer probe trigger as CLI is already going to take care of generating the same.
