DPM Server 2016 is running on a Windows 2016 Hyper V Host in a Windows 2016 Guest VM
Creating a new Protection Group consisting of partial volumes of a Windows 2008 R2 (physical server). It's been stuck on Calculating Data Size on the "Review Disk Storage Allocation" screen of the Create New Protection Group wizard. It does this every time I attempt it for that server needing protecting. It never finishes. The total data size on disk is 1.2TB of a 1.4TB disk.
(This current time, its been at least 5 hours)
