Introspecting a file on ZFS

Derived from: http://www.c0t0d0s0.org/archives/7485-Find-out-in-depth-information-about-a-file-in-ZFS.html

Sometimes you need to acquire in-depth information about a file that isn't exposed by other commands like stat.

ZFS allows you to do this with zdb. However there's a confusing problem. If you're just trying to access a file on your root pool that doesn't have any nested datasets, you need use rpool/ instead of just rpool (assuming "rpool" is the name of your root pool).

Here's 3 examples of acquiring information on /filepath.

# Enables the WinRM service and sets up the HTTP listener
Enable-PSRemoting -Force

# Opens port 5985 for all profiles
$firewallParams = @{
    Action      = 'Allow'
    Description = 'Inbound rule for Windows Remote Management via WS-Management. [TCP 5985]'
    Direction   = 'Inbound'
    DisplayName = 'Windows Remote Management (HTTP-In)'
    LocalPort   = 5985
