From 63b52c4936a2e679639c38ef51a50aa8ca1c5c07 Mon Sep 17 00:00:00 2001 From: Junxiao Bi Date: Mon, 19 Sep 2016 14:44:44 -0700 Subject: [PATCH] Revert "ocfs2: bump up o2cb network protocol version" This reverts commit 38b52efd218b ("ocfs2: bump up o2cb network protocol version"). This commit made rolling upgrade fail. When one node is upgraded to new version with this commit, the remaining nodes will fail to establish connections to it, then the application like VMs on the remaining nodes can't be live migrated to the upgraded one. This will cause an outage. Since negotiate hb timeout behavior didn't change without this commit, so revert it.
