API v1.0 and Zvol Extent

[JM2K69]

Hi I create a Powershell module to configure Freenas with API I have one problem to create an extent with a ZVOL This picture show to Extent the first Extent with the ID 1 is create with the Web GUI and the second with the API and my module.

When I look the documentation for the API freenas Documentation create a extent using zvol. There is an example :

{
"iscsi_target_extent_type": "Disk",
"iscsi_target_extent_name": "zvolextent",
"iscsi_target_extent_disk": "zvol/tank/zvolextent"
}
My extent is successfully created but when I open the Web GUI My Extent don't have a device configured for my Extent name demo2, and in the documentation All setting are define :
JSON Parameters:

• iscsi_target_extent_name (string) – identifier of the extent
• iscsi_target_extent_type (string) – File, Disk
• iscsi_target_extent_path (string) – path to the extent (for File type)
• iscsi_target_extent_disk (string) – path to the disk or zvol (for Disk type) e.g. “zvol/tank/zvol1”, “ada1”
• iscsi_target_extent_filesize (string) – size of extent, 0 means auto, a raw number is bytes, or suffix with KB, MB, TB for convenience
• iscsi_target_extent_insecure_tpc (boolean) – allow initiators to xcopy without authenticating to foreign targets
• iscsi_target_extent_xen (boolean) – Xen initiator compat mode
• iscsi_target_extent_comment (string) – user description
• iscsi_target_extent_avail_threshold (integer) – Remaining dataset/zvol capacity warning threshold
• iscsi_target_extent_blocksize (integer) – Logical Block Size
• iscsi_target_extent_pblocksize (boolean) – Disable Physical Block Size Reporting
• iscsi_target_extent_rpm (string) – Unknown, SSD, 5400, 7200, 10000, 15000
• iscsi_target_extent_serial (string) – Serial number for the logical unit
• iscsi_target_extent_ro (boolean) – Read-only extent

Or if you look the Extend created by the Web UI with a ZVOL the iscsi_target_extent_type is ZVOL Or the doc mention File or Disk an If i tried to set to ZVOL I have a Error 409 conflict. My question is How to create a Extent based on ZVOL.
