删除 ZFS 委托权限（示例）

可以使用 zfs unallow 命令删除已授予的委托权限。例如，用户 cindy 在 tank/cindy 文件系统上具有 create、destroy、mount 和 snapshot 权限。

# zfs allow cindy create,destroy,mount,snapshot tank/home/cindy
# zfs allow tank/home/cindy
---- Permissions on tank/home/cindy ----------------------------------
Local+Descendent permissions:
        user cindy create,destroy,mount,snapshot

以下 zfs unallow 语法将从 tank/home/cindy 文件系统中删除用户 cindy 的 snapshot 权限：

# zfs unallow cindy snapshot tank/home/cindy
# zfs allow tank/home/cindy
---- Permissions on tank/home/cindy ----------------------------------
Local+Descendent permissions:
        user cindy create,destroy,mount
cindy% zfs create tank/home/cindy/data
cindy% zfs snapshot tank/home/cindy@today
cannot create snapshot 'tank/home/cindy@today': permission denied

作为另一个示例，用户 mark 在 tank/home/mark 文件系统上具有以下权限：

# zfs allow tank/home/mark
---- Permissions on tank/home/mark ----------------------------------
Local+Descendent permissions:
        user mark create,destroy,mount
-------------------------------------------------------------

以下 zfs unallow 语法将从 tank/home/mark 文件系统中删除用户 mark 的所有权限：

# zfs unallow mark tank/home/mark

以下 zfs unallow 语法将删除对 tank 文件系统的权限集。

# zfs allow tank
---- Permissions on tank ---------------------------------------------
Permission sets:
        @myset clone,create,destroy,mount,promote,readonly,snapshot
Create time permissions:
        create,destroy,mount
Local+Descendent permissions:
        group staff create,mount
# zfs unallow -s @myset tank
# zfs allow tank
---- Permissions on tank ---------------------------------------------
Create time permissions:
        create,destroy,mount
Local+Descendent permissions:
        group staff create,mount
