ERROR :
DISK MANAGEMENT : THERE IS NOT ENOUGH SPACE AVAILABLE ON THE DISK(S) TO COMPLETE THIS OPERATIONAL.
Since my virtual server was running low on disk space, I had to increase the disk volume from the Hyper-V manager to my server. While expanding the volume, I had the error and here is what I did to resolve it !!
FIX :
1. Open Disk Management ( Windows + R and "diskmgmt.msc" )
2. Click on Action then Rescan Disks
3. Extend your volume as desire.
