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。

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

即使我手动分享也没有任何反应

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！
