Afternoon,

So I've expended many drives without any issues in Windows 2008 R2 and windows 2012 R2. It's really easy and works well except that I can't use the new space.

The drive was 100Gb and I have 15 Gb left.
I expended the drive in ESX to 150 Gb
I expended the drive in Windows
Drive manager shows that the drive is expended.
Go into properties for the drive and it still shows 100 Gb

I'm on the hunt for error messages now and google isn't telling me anything. Wondering if anyone has run into this before?

Thanks
 
I've ran into this before, and I swear I fixed it it with diskpart. I goggled around a bit, and I think this was the fix.
diskpart
list vol
select vol # (# is the volume you want)
extend filesystem
exit

Should show up right away without a reboot if it works. Note that every time I've had this happen, it was in a VM. Must be something wonky with either the VMWare drivers, or the way the VM sees the new drive space that prevents Windows from actually picking up the new size properly after extending with Disk Management.
 
Your original approach should also have worked. Did you refresh the disk in Disk Management mmc?
 
Yep, tried that and disk management was showing me 150gb disk size but usable and properties was still set to 100gb. Even diskpart showed me 150gb but the space wasn't usable until I did the extend filesystem.

I've done the expansion of drives on about a dozen other 2012 machines and never ran into this problem, just expand the drive in the drive manager and kapow it's done. This time was a bit more interesting.
