Ubuntu Xenial (16.04) “zfs share”命令不适用于 SMB 共享

  • 772

我在 Ubuntu Xenial (16.04) 上的 ZFS 问题

多年来，我一直在包维护者的 zfsonlinux.org 站点上运行 ZFS。事情一直很好。但是最近我在 Ubuntu 16.04 发布时升级到了它。我很高兴它内置了 ZFS。到目前为止，除了一件事之外，一切都运行良好。

zfs share -a并且zfs share filesystem不工作，因此，每当我重新启动系统时，zfs-share.service都不会启用在 ZFS 中配置的 SMB 共享。对于 Debian 8.x 或更早版本的 Ubuntu 以及来自 zfsonlinux.org 的软件包，我没有遇到这个问题。

我已将此作为 ZoL 和 Ubuntu 的错误提交。我不知道那会走多远。我不知道这是一个错误还是 Ubuntu 或我的问题。所以我也希望这里的人会有一个想法或者可以确认这是他们也遇到的问题。

ZoL：https ://github.com/zfsonlinux/zfs/issues/4999

Ubuntu：https ://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1615405

有关我的实际问题，请参阅底部。

调试信息

没有股份！我也在几台客户端计算机上进行了验证 - 这就是发现问题的方式。

重新启动后的Systemd zfs-share.status似乎很好

数据集配置正确

root@igor:~# zfs get sharesmb pool2/Media
NAME         PROPERTY  VALUE     SOURCE
pool2/Media  sharesmb  on        local
root@igor:~# zfs get sharesmb pool2/home
NAME        PROPERTY  VALUE     SOURCE
pool2/home  sharesmb  on        local

即使我手动分享也没有任何反应

root@igor:~# zfs share -a
root@igor:~# net usershare list
root@igor:~# ls /var/lib/samba/usershares/
root@igor:~#

共享特定文件系统时已共享消息

root@igor:~# zfs share pool2/home
cannot share 'pool2/home': filesystem already shared

ZFS 代码使用 /etc/dfs/sharetab 但 Linux/Samba 不使用（启动后） https://github.com/zfsonlinux/zfs/issues/190

root@igor:~# cat /etc/dfs/sharetab 
/pool2/home     -       smb     on
/pool2/Media    -       smb     on

strace -y zfs share -a看起来 ZFS 可能没有尝试共享数据集，因为它在 /etc/dfs/sharetab 中找到它们，但我可能误解了这一点。

共享数据集的唯一方法是将sharesmb属性重置为on

root@igor:~# zfs set sharesmb=on pool2/home
root@igor:~# net usershare list
pool2_home
root@igor:~# zfs set sharesmb=on pool2/Media
root@igor:~# net usershare list
pool2_home
pool2_Media

我的问题

我知道我可以通过在 /etc/rc.local 中添加这些条目来解决这个问题

zfs set sharesmb=on pool2/Main
zfs set sharesmb=on pool2/home

我会的。但是有谁知道为什么zfs share -a不能按预期工作（一如既往）？有没有其他人经历过这个？也许它会影响所有 Ubuntu Xenial 安装，或者可能只是我。即使没有修复程序并且这是一个错误，我也想知道。

谢谢！

    我找到了答案，不幸的是它并不好

    我在 ZoL 票务系统上得到了答案。显然这个问题是已知的，并以某种方式进入了 Ubuntu，而 Ubuntu 让它飞起来：

    https://github.com/zfsonlinux/zfs/issues/4999

    恐怕众所周知的问题。目前在 ZoL 中的 SMB 实现严重损坏！我已经完全重写了它，但是没有兴趣将它合并。

    虽然它被称为一个众所周知的问题，但它对我来说似乎并不为人所知。事实上它几个月前就开始工作了，我找不到任何票或谷歌搜索结果。

    个人咆哮- 如果您对答案感到满意，请停止阅读此处。

    我不知道 Ubuntu 如何处理这样的错误。我记得以前我管理 RedHat 系统时，他们实际上会修复其他人代码中的错误。太好了。在 Ubuntu LTS 中有一个“众所周知的”错误真的让我很烦恼，让我想知道它们都是其他软件包，还有哪些其他众所周知的错误被忽略了。

    开发者在 github 上的这个 bug 报告中的评论非常有趣。当有可用的补丁程序时，ZoL 故意在他们的软件中留下错误。过去版本中的补丁！这让我非常失望。让我感到惊讶的是，Ubuntu 不会自己应用补丁，而是假装该软件在他们的新 LTS 版本上运行并且稳定。

  2. 我最近在将我的一个储物箱从 14.04 更新到 16.04 后遇到了这个问题

    奇怪的是，我在更新的第一个盒子上没有遇到这个问题，尽管那是一个全新的重新安装而不是 dist 升级。

    我发现主要问题是尽管设置了所有 sharemb=on 参数，但 /var/lib/samba/usershares/ 中没有用户共享条目

    所以，我只是使用另一个盒子的文件作为模板手动创建了一个，重新启动了 samba，瞧，一切都恢复了。

    不过，非常笨拙。
