前言：
zfs是一个强大的新一代文件系统，但由于开源证书的问题，该项技术并没有合并到主流Linux操作系统内核当中，这个不得不说是一个非常巨大的遗憾。
ok，那么zfs到底如何强悍就不在本文内吹捧了，直接记录centos7下编译安装该zfs文件系统的过程
一、
zfs文件系统的版本介绍和安装方式介绍
zfs文件系统的一些基本特点
第一点，zfs文件系统是和操作系统的内核深度绑定的，就像ntfs文件系统一样，Linux要使用此类文件系统，必须要内核方面支持。
第二点，zfs文件系统是可以和其它文件系统混用的，就像我们现在的操作系统内所作的事情一样，比如，有的操作系统根区文件系统是ext4，但并不妨碍我们使用xfs作为数据盘的文件系统，这个也是标准的部署方案。
第三点，zfs文件系统对于数据库这样的应用非常有用，可以做到秒级恢复，本文在centos7系统内尝试编译安装zfs文件系统
zfs文件系统的版本介绍
zfs文件系统在epel源里面好像是有，但版本过低，是0.7.3版本，该版本和centos7是完全不兼容的，现在的版本最新是2.4.1，源码下载地址是： https://github.com/openzfs/zfs/releases
选用2.4.1版本的原因是最新的zfs文件系统对于一些安全漏洞以及一些使用上的bug问题做了比较多的改善
zfs文件系统的安装方式
zfs文件系统的安装方式主要是两种，第一种是二进制方式安装，也就是最为常用的yum安装方式，但该方式对于版本的选择太少，局限性过高，第二种方式是源码编译方式，该方式比较复杂，但安装的成功率会更高，并且对于上面的版本冲突问题也能够解决的比较好。
本文采用源码编译的方式编译安装部署zfs-2.4.1，该版本是2025年12月发布，综合各方面来说，还是比较好的
二，zfs文件系统编译前的准备工作
1，硬件资源
计划在VMware虚拟机内实现zfs文件系统的编译，因此，先给该虚拟机添加3块硬盘，并可在系统中看到，zfs文件系统对于内存需求较高，因此是8G
三，centos内核版本
本例使用的是5.4.266内核版本
bash
[root@centos1 zfs-2.4.1]# uname -a
Linux centos1 5.4.266-1.el7.elrepo.x86_64 #1 SMP Mon Jan 8 23:23:50 EST 2024 x86_64 x86_64 x86_64 GNU/Linux后面改成了5.4.69内核版本
四，编译环境的创建
bash
yum install autoconf automake libtool -y
./autogen.sh
yum install -y zlib-devel libuuid-devel libblkid-devel libattr-devel libtirpc-devel openssl-devel bc五，zfs源码预编译和编译
第一次编译报错如下：
bash

*** kernel as usual.经查找资料，发现本例使用的内核版本是长期支持版本5.4.266，不支持动态内核编译，因此，更换内核版本为3.10.1160，内核重新安装后重启启用新内核
bash
yum remove kernel-lt-* -y
yum install -y kernel-3.10.0-1160.118.1.el7.x86_64 kernel-devel-3.10.0-1160.118.1.el7.x86_64 kernel-headers-3.10.0-1160.118.1.el7.x86_64在使用3.10.1160内核后，仍然报错，因此采用新的内核，直接 编译，编译完成后的内核版本如下（我自己设定的名字，因此，大家不要太纠结这个版本号问题）

编辑有问题的头文件，为缺失的宏提供默认值：
# 编辑 modes.h
vim /root/zfs-2.4.1/module/icp/include/modes/modes.h
找到第45行附近（大约）：
#define CAN_USE_GCM_ASM (HAVE_VAES && HAVE_VPCLMULQDQ ? 2 : 1)
修改为：
#ifndef HAVE_VAES
#define HAVE_VAES 0
#endif
#ifndef HAVE_VPCLMULQDQ
#define HAVE_VPCLMULQDQ 0
#endif
#define CAN_USE_GCM_ASM (HAVE_VAES && HAVE_VPCLMULQDQ ? 2 : 1)该报错可以忽略，但预编译的时候没有选择忽略，因此，报错，只是一个加密功能的问题，zfs文件系统的核心功能没有改变
make继续报错，如下：

# 编辑 gcm.c
vim /root/zfs-2.4.1/module/icp/algs/modes/gcm.c
找到第856行附近，注释掉有问题的行：
//{ "avx2-vaes", IMPL_AVX2 }, // 暂时禁用然后就一路畅通，zfs文件系统终于顺利编译完成了
稍微总结下，由于是虚拟机的缘故，一些硬件检测导致编译失败，因此这些优化措施是可以禁用掉的，如果是真实物理机，估计很可能不会有这些报错
测试zfs文件系统是否安装成功：
bash
[root@centos1 zfs-2.4.1]# lsmod |grep zfs
[root@centos1 zfs-2.4.1]# modprobe zfs
[root@centos1 zfs-2.4.1]# lsmod |grep zfs
zfs 5554176 0
spl 122880 1 zfs看到内核加载了zfs文件系统的模块，标志此次编译安装完成
六，zfs的rpm安装包生成
经过上面的一番操作，make出了zfs文件系统，那么，如果每个机器上都编译一次，未免太不人性化了，因此，还是需要直接编译出centos7x86_64的操作系统用的rpm安装包
狠简单的一个命令，make rpm就可以了，但是，我这里要说一下但是，还是缺了一些编译依赖，编译依赖解决后，还需要修改一下makefile文件，先说编译依赖问题：
bash
yum install -y rpm-build ncompress libudev-devel libaio-devel bc编译依赖解决完后，打开Makefile文件，vim /root/zfs-2.4.1/Makefile，将HAVE_RPMBUILD = no 修改为HAVE_RPMBUILD = yes
后面的rpm生成就非常顺畅了，生成的rpm包如下：
bash
[root@centos1 zfs-2.4.1]# ls -alh *.rpm
-rw-r--r-- 1 root root 1.6M May 3 20:56 kmod-zfs-5.4.69-2.4.1-1.el7.x86_64.rpm

-rw-r--r-- 1 root root 28M May 3 20:58 zfs-test-2.4.1-1.el7.x86_64.rpm从这些rpm包的名字可以看出，zfs文件系统是和操作系统内核强相关的，因此，在这里做一个总结，即使是使用rpm包安装，也必须要编译或者yum安装大于等于4.18的版本
