Ubuntu 14.04 升级到 16.04 破坏了我的 ZFS

我刚刚将 Ubuntu 从 14.04 升级到 16.04，这似乎破坏了 ZFS。我按照说明这里并清除了所有旧的 ZFS 软件包。然后我从默认的 16.04 PPA 安装了 zfsutils-linux，但每当我运行任何 ZFS 命令时，我都会收到以下错误：

:~$ sudo zfs get all
The ZFS modules are not loaded.
Try running '/sbin/modprobe zfs' as root to load them.

我尝试使用 modprobe 按照错误消息的建议：

:~$ sudo /sbin/modprobe zfs
modprobe: ERROR: could not insert 'zfs': Invalid argument

看起来好像没有安装 ZFS，但是 apt-get 显示已经安装：

:~$ sudo apt-get install zfsutils-linux
Reading package lists... Done
Building dependency tree
Reading state information... Done
zfsutils-linux is already the newest version (0.6.5.6-0ubuntu16).
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
N: Ignoring file '50unattended-upgrades.ucf-dist' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension

我还亲自来到我的机器上，而不是使用 SSH 来观察启动过程，并看到许多 ZFS 项目在启动时失败，其中一个我认为是关于依赖关系的，但它过去得太快了，我没法全部读完。我试图通过查看启动日志来查看它们说了什么，但我找不到与启动期间显示的输出相匹配的启动日志文件。我可以在哪里查看启动时实际失败的原因？

进一步有趣的发现是，如果我只使用 zfs 命令，我会得到“缺少命令”输出，但是当添加任何命令时，我都会收到上述相同的错误消息。

:~$ zfs
missing command

where 'command' is one of the following:

Each dataset is of the form: pool/[dataset/]*dataset[@name]

For the property list, run: zfs set|get

For the delegated permission list, run: zfs allow|unallow

我还能做什么来解决此 ZFS 安装问题？

答案1

从 12.04 升级到 16.04 时也遇到了类似的问题。最后终于可以正常工作了，但我记不清具体做了什么（第 2 步不太明显）。

  1. zfs删除包括 PPA 在内的旧软件包，请参阅使用 ubuntu-zfs 从 ubuntu server 14.04 LTS 升级到 16.04 LTS
  2. 删除：spl-dkms和（我认为）spl
  3. 重新安装zfs

答案2

以下一系列root命令为我解决了这个问题。

apt clean
apt update
apt purge zfs*
apt remove spl dkms spl-dkms
apt autoremove
add-apt-repository --remove ppa:zfs-native/stable

apt install zfsutils-linux
apt install spl-dkms

reboot -n
