Support Reallocation of VHDs on Storage Spaces
The struggle is real, my friends. When you have a storage space with 4 disks and create a new virtual disk with parity over all those 4 physical disks, the data is spread out as you'd expect. But if you run low on space and you add another disk, the data already on the vhd cant benefit from the new disk. You have to create a new virtual disk and copy the data from the old to the new one. The problem is described here:
So please let us edit a virutal disk and add more physical disk the data should be saved on. Of coouse, some reorganization of the data is required and that may take some time. But atleast it is automated and does still work even if your actual disks are already almost full.
