Workaround found here https://xcp-ng.org/forum/post/94626
Seems like turning "Use NDB to transfer disk if available" switch ON and save backup job,
then turn the switch OFF and save backup job again, will fix the issue.
Thanks to @RobWhalley and have a nice day everyone.

@JeffBerntsen That's why I meant, the way to install written in the first post still work in 8.3, the script still work as expected also, it basically only create the VG/LV needed on hosts before you create the SR.
Got it. Thanks!
