[libvirt-users] Online Disk Resize with Windows Server 2016

[Andre Goree]

I'm having an issue when resizing a disk (a Ceph RBD disk, though the 
type of disk shouldn't matter, I'd think) attached to a Windows Server 
2016 guest.

After I resize the disk, the newly-created disk space is _not_ 
recognized by the server.  Even after running Action > Rescan from the 
Disk Management app, the new disk space does not show.  However, when I 
perform the same resize on a Windows Server 2012 or even a Sever 2008 
system, the Action > Rescan works fine and the newly-created disk space 
is recognized without needed to detach the drive or reboot the VM.

Does anyone have an idea of what may have changed in Windows 2k16 that 
might be causing this?  Possibly some undocumented registry change or 
something?
