Compile drbd9 on CentOS7
背景：最近CentOS7系统升级到最新内核后，使用从yum源中安装的drbd9导致内核崩溃

随后决定自己编译安装，下面是制作rpm包的过程
编译环境
OS：CentOS7
Kernel ：3.10.0-862.2.3
下载软件包
https://www.linbit.com/en/drbd-community/drbd-download/
drbd-9.0.14-1.tar
drbd-utils-9.4.0.tar
升级内核
yum install kernel kernel-devel kernel-headers
安装编译需要的工具
yum install gcc make automake gcc-c++ flex
编译drbd内核模块
tar xzvf drbd-9.0.14-1.tar
cd /drbd-9.0.14-1
make
...
Module build was successful.
=======================================================================
With DRBD module version 8.4.5, we split out the management tools
into their own repository at https://github.com/LINBIT/drbd-utils
(tarball at http://links.linbit.com/drbd-download)
That started out as "drbd-utils version 8.9.0",
has a different release cycle,
and provides compatible drbdadm, drbdsetup and drbdmeta tools
for DRBD module versions 8.3, 8.4 and 9.
Again: to manage DRBD 9 kernel modules and above,
you want drbd-utils >= 9.3 from above url.
=======================================================================
制作rpm包
make kmp-rpm
编译drbd-utils
tar xzvf drbd-utils-9.4.0.tar
cd drbd-utils-9.4.0
直接生成drbd.spec文件，制作rpm包，因为源码bug的关系，需要手动建立/root/rpmbuild/SOURCES目录
mkdir /root/rpmbuild/SOURCES
生成Makefile文件
./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc --without-83support --without-84support
生成drbd.spec文件
./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc --without-83support --without-84support --enable-spec
make rpm
...
You have now:
/root/rpmbuild/RPMS/x86_64/drbd-9.4.0-1.el7.centos.x86_64.rpm
/root/rpmbuild/RPMS/x86_64/drbd-utils-9.4.0-1.el7.centos.x86_64.rpm
/root/rpmbuild/RPMS/x86_64/drbd-xen-9.4.0-1.el7.centos.x86_64.rpm
/root/rpmbuild/RPMS/x86_64/drbd-udev-9.4.0-1.el7.centos.x86_64.rpm
/root/rpmbuild/RPMS/x86_64/drbd-pacemaker-9.4.0-1.el7.centos.x86_64.rpm
/root/rpmbuild/RPMS/x86_64/drbd-heartbeat-9.4.0-1.el7.centos.x86_64.rpm
/root/rpmbuild/RPMS/x86_64/drbd-bash-completion-9.4.0-1.el7.centos.x86_64.rpm
/root/rpmbuild/RPMS/x86_64/drbd-man-ja-9.4.0-1.el7.centos.x86_64.rpm
/root/rpmbuild/RPMS/x86_64/drbd-debuginfo-9.4.0-1.el7.centos.x86_64.rpm
这样编译出来的包安装会可能会出现以下问题：
[root@lms-0 ~]# rpm -ivh drbd-utils-9.4.0-1.el7.centos.x86_64.rpm

解决办法：修改drbd.spec.in文件

%bcond_without bashcompletion
%bcond_without sbinsymlinks
+ %if %{rhel} == 7
+ %undefine with_sbinsymlinks
+ %endif
# --with xen is ignored on any non-x86 architecture
%bcond_without xen
%bcond_without 83support
重新打包，安装成功
