如果安装了 rdma-core，系统升级可能会导致 Yum 安装不需要 32 位软件包
在 Red Hat Enterprise Linux 7.4 中，rdma-core.noarch 软件包由 rdma-core.i686 和 rdma-core.x86_64 弃用。在系统升级过程中，
Yum 将原始软件包替换为两个新的软件包，并安装任何所需的依赖项。这意味着 32 位软件包以及可能安装大量 32 位依赖项，即使不需要，也是如此。
要临时解决这个问题，您可以使用带有 --exclude=\\*.i686 选项的 yum update 命令，或者在升级后使用 yum remove rdma-core.i686 来移除 32 位软件包。(BZ#1458338)
