Unclear About Warning Regarding Expand Volume for Hyperconverged Storage Space Direct.

Frequent Visitor

I’ve come across a vague warning on the extending volumes page and I’m not exactly sure what this means. We use Hyper-V virtual machines on the CSV storage volume in a hyper converged storage space direct setup. Does this warning indicate that we cannot expand the CSV volume because it is being used by virtual machines?

Warning

 

Not supported: resizing the underlying storage used by Storage Spaces Direct. If you are running Storage Spaces Direct in a virtualized storage environment, including in Azure, resizing or changing the characteristics of the storage devices used by the virtual machines isn't supported and will cause data to become inaccessible. Instead, follow the instructions in the Add servers or drives section to add additional capacity before expanding volumes.
