在我重新启动CentOS服务器之后，ZFS不起作用：
$ sudo zfs list The ZFS modules are not loaded. Try running '/sbin/modprobe zfs' as root to load them. $ sudo modprobe zfs modprobe: FATAL: Module zfs not found. 我的操作系统版本是CentOS Linux release 7.2.1511 (Core)和uname -r打印3.10.0-327.18.2.el7.x86_64 。
我注意到一些软件包似乎在机器启动时自动更新 – 我在/var/log/yum.logfind以下条目：
Feb 28 10:11:17 Updated: epel-release-7-9.noarch Feb 28 10:11:29 Updated: openblas-openmp64-0.2.19-4.el7.x86_64 Feb 28 10:11:30 Updated: openblas-threads64_-0.2.19-4.el7.x86_64 Feb 28 10:11:31 Updated: openblas-openmp-0.2.19-4.el7.x86_64 Feb 28 10:11:32 Updated: openblas-serial64_-0.2.19-4.el7.x86_64 Feb 28 10:11:33 Updated: openblas-threads-0.2.19-4.el7.x86_64 Feb 28 10:11:34 Updated: openblas-threads64-0.2.19-4.el7.x86_64 Feb 28 10:11:35 Updated: openblas-0.2.19-4.el7.x86_64 Feb 28 10:11:36 Updated: openblas-openmp64_-0.2.19-4.el7.x86_64 Feb 28 10:11:37 Updated: openblas-serial64-0.2.19-4.el7.x86_64 Feb 28 10:11:37 Updated: openblas-devel-0.2.19-4.el7.x86_64 Feb 28 10:11:43 Updated: libtirpc-0.2.4-0.8.el7.x86_64 Feb 28 10:11:44 Updated: 1:nfs-utils-1.3.0-0.33.el7.x86_64 Feb 28 10:12:22 Installed: kernel-devel-3.10.0-514.6.2.el7.x86_64 Feb 28 10:12:27 Updated: x2goserver-4.0.1.20-1.el7.x86_64 Feb 28 10:12:27 Updated: x2goserver-xsession-4.0.1.20-1.el7.x86_64
从dkms status看来，ZFS没有安装：
$ sudo dkms status nvidia, 352.93, 3.10.0-327.10.1.el7.x86_64, x86_64: installed nvidia-uvm, 352.93, 3.10.0-327.10.1.el7.x86_64, x86_64: installed (original_module exists) spl, 0.6.5.9: added zfs, 0.6.5.9: added nvidia-uvm, 352.93, 3.10.0-229.el7.x86_64, x86_64: installed-weak from 3.10.0-327.10.1.el7.x86_64 nvidia, 352.93, 3.10.0-327.18.2.el7.x86_64, x86_64: installed-weak from 3.10.0-327.10.1.el7.x86_64 nvidia-uvm, 352.93, 3.10.0-327.18.2.el7.x86_64, x86_64: installed-weak from 3.10.0-327.10.1.el7.x86_64 nvidia, 352.93, 3.10.0-327.4.4.el7.x86_64, x86_64: installed-weak from 3.10.0-327.10.1.el7.x86_64 nvidia-uvm, 352.93, 3.10.0-327.4.4.el7.x86_64, x86_64: installed-weak from 3.10.0-327.10.1.el7.x86_64
当我尝试做dkms install我得到一个错误：
$ sudo dkms install zfs/0.6.5.9 Error! echo Your kernel headers for kernel 3.10.0-327.18.2.el7.x86_64 cannot be found at /lib/modules/3.10.0-327.18.2.el7.x86_64/build or /lib/modules/3.10.0-327.18.2.el7.x86_64/source.
kernel-headers的版本似乎与kernel相匹配，但版本库中没有相同版本的kernel-devel软件包。

我应该如何继续？
我想升级内核（释放514.6.2.el7 ），但是我不喜欢这样做，因为我担心它可能会破坏事情。 （我inheritance了这个服务器作为临时pipe理员，我不明白它是如何configuration的。
