需要ZFS Diff - diff委托权限。

Question

当今天以非根用户身份运行zfs diff时，我得到了一个错误：

Unable to obtain diffs: 
   The sys_mount privilege or diff delegated permission is needed
   to execute the diff ioctl

在谷歌搜索diff delegated permission没有给出任何结果。

什么是diff委托权限，以及如何绕过这个块允许非根用户运行zfs diff。

Answer 1

通过发出以下命令，将diff权限在ZFS中授予有关用户以解决此问题：

sudo zfs allow  diff /

向dataset rpool/USERDATA上的D4授予diff权限：

sudo zfs allow jblogs diff rpool/USERDATA
