You can use the following command to display permissions:
# zfs allow dataset
This command displays permissions that are set or allowed on the specified dataset. The output contains the following components:
Permission sets
Individual permissions or create-time permissions
Local dataset
Local and descendant datasets
Descendant datasets only
The following output indicates that user cindy has create, destroy, mount, snapshot permissions on the system1/cindy file system.
# zfs allow system1/cindy ------------------------------------------------------------- Local+descendant permissions on (system1/cindy) user cindy create,destroy,mount,snapshotExample 49 Displaying Complex Delegated Administration Permissions
The output in this example indicates the following permissions on the pool/fred and pool file systems.
For the pool/fred file system:
Two permission sets are defined:
@eng (create, destroy, snapshot, mount, clone, promote, rename)
@simple (create, mount)
Create-time permissions are set for the @eng permission set and the mountpoint property. Create-time means that after a file system set is created, the @eng permission set and the permission to set the mountpoint property are delegated.
User tom is delegated the @eng permission set, and user joe is granted create, destroy, and mount permissions for local file systems.
User fred is delegated the @basic permission set, and share and rename permissions for the local and descendant file systems.
User barney and the staff group are delegated the @basic permission set for descendant file systems only.
For the pool file system:
The permission set @simple (create, destroy, mount) is defined.
The group staff is granted the @simple permission set on the local file system.
Here is the output for this example:
$ zfs allow pool/fred ---- Permissions on pool/fred ---------------------------------------- Permission sets: @eng create,destroy,snapshot,mount,clone,promote,rename @simple create,mount Create time permissions: @eng,mountpoint Local permissions: user tom @eng user joe create,destroy,mount Local+descendant permissions: user fred @basic,share,rename user barney @basic group staff @basic ---- Permissions on pool --------------------------------------------- Permission sets: @simple create,destroy,mount Local permissions: group staff @simple
