If you are getting this error when you try to expand your storage spaces Vdisk, and you are using StorageTiers.
you can expand your volume by using powershell instead
run the following command to get the names of your StorageTiers
1 |
Get-VirtualDisk <Vdisk FriendlyName> | Get-StorageTier | Select FriendlyName |
In my case the name is VeeamVolume
and then expand the desired StorageTier
1 |
Get-StorageTier <StorageTier FriendlyName> | Resize-StorageTier -Size <Size> |
and after the resize
