“There is not enough space available on the disk(s) to complete this operation” when expanding a disk volume

You run into the following error when you try to extend a disk volume, even the additional space is shown in your Disk Management:


“There is not enough space available on the disk(s) to complete this operation.”


Try to rescan the disks – then it should work without any problems:
