From 7efd84b1b743d3a91e23fd97dbf8a1d89b0d1f44 Mon Sep 17 00:00:00 2001 From: Mohammed Rafi KC Date: Thu, 16 Oct 2014 11:28:33 +0530 Subject: rdma: client connection establishment takes more time Backport of http://review.gluster.org/8934 For rdma type only volume client connection establishment with server takes more than three seconds. Because for tcp,rdma type volume, will have 2 ports one for tcp and one for rdma, tcp port is stored with brickname and rdma port is stored as "brickname.rdma" during pamap_sighin. During the handshake when trying to get the brick port for rdma clients, since we are not aware of server transport type, we will append '.rdma' with brick name. So for tcp,rdma volume there will be an entry with '.rdma', but it will fail for rdma type only volume. So we will try again, this time without appending '.rdma' using a flag variable need_different_port, and it will succeed, but the reconnection happens only after 3 seconds. In this patch for rdma only type volume we will append '.rdma' during the pmap_signin. So during the handshake we will get the correct port for first try itself. Since we don't need to retry , we can remove the need_different_port flag variable.
