Ubuntu 14.04到16.04升级打破了我的ZFS
我刚刚将Ubuntu从14.04升级到16.04，这似乎打破了ZFS。 我按照这里的指示清除了所有旧的ZFS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作为错误消息建议：
:~$ sudo /sbin/modprobe zfs modprobe: ERROR: could not insert 'zfs': Invalid argument
似乎没有安装ZFS，但apt-get显示它是：
:~$ 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
我还亲自去了我的机器，而不是使用SSH来观看启动，并在启动时看到了一些ZFS项目失败，其中一个我认为有关于依赖关系的东西，但是我读得太快了。 我试图通过查看启动日志来查看他们所说的内容，但我一直无法找到与启动期间显示的输出相匹配的启动日志文件。 我在哪里可以看到启动时实际失败的是什么？
更有趣的发现是，如果我只使用zfs命令，我会得到’missing command’输出，但是当添加任何命令时，我从上面得到相同的错误消息。
:~$ zfs missing command usage: zfs command args ... where 'command' is one of the following: create [-p] [-o property=value] ... create [-ps] [-b blocksize] [-o property=value] ... -V destroy [-fnpRrv] destroy [-dnpRrv] @[%][,...] destroy # snapshot|snap [-r] [-o property=value] ... @ .. . rollback [-rRf] clone [-p] [-o property=value] ... promote rename [-f] rename [-f] -p rename -r bookmark list [-Hp] [-r|-d max] [-o property[,...]] [-s property]...

我还可以做些什么来解决这个ZFS安装问题？
有一个类似的问题从12.04升级到16.04。 最后让它工作，但不记得我做了什么（第2步不明显）。
- 删除旧的
zfs包，包括PPA，请参阅使用ubuntu-zfs从ubuntu服务器14.04 LTS升级到16.04 LTS - 删除：
spl-dkms和（我认为）spl - 重新安装
zfs
以下系列的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
