I have done most of the explaining in another post on how the permissions work with a zfs cifs share - link here.
In this post I’m going to show an example of how to add multiple groups / users to a specific folder. Which then recursively adds its ACL’’s to any child objects. Its essentially like the other commands i used, but with an extra line per user or group you want to configure;
O.k. from this point I’m assuming you have created your zfs shares via the zfs command and renamed appropriately like so….. (if you havent setup cifs yet then check read this)
zfs set sharesmb=on protected/backup
zfs set sharesmb=name=backup protected/backup
Now to check your current shares type…
sharemgr show
zfs
zfs/protected/backup backup=/protected/backup
zfs/protected/photos photos=/protected/photos
Now its time to look at NFSv4 ACL’s. This page has a great explanation of ACL’s and how to set things up. http://cuddletech.com/blog/pivot/entry.php?id=939
