zfs share doesn't work

[Ryan Babchishin]

I'm testing on Ubuntu 16.04 with the included zol 0.6.5.

I have also reported this bug here: https://github.com/zfsonlinux/zfs/issues/4999

zfs share and zfs share -a just don't work. zfs set sharesmb=on pool/dataset works fine. I discovered that the shares are listed in /etc/dfs/sharetab but don't work. If I reboot or anything and try to share them again with zfs share, it will not work. net usershare list displays nothing. And of course because of this all shares are lost on every reboot.

Despite a dataset having the sharesmb=on value set, it will not share with zfs share -a and if I use zfs share pool/dataset it says: cannot share 'pool/dataset': filesystem already shared, when net usershare list shows nothing**. Samba is running and the shares appear in /etc/dfs/sharetab, not that that is helping me.

I've detailed a bunch of stuff at serverfault... if that's not good enough, I can bring some of it over here:

I've asked for an update on the status of this big in the zfs bug tracker as it seems to have gone no where.

[Colin Ian King (colin-king)]

Still no update from upstream.

..still no upstream update on this.

Should be fixed at least since 20.04 LTS
