Windows Failover Cluster Says Not Enough Disk Space as it's not seeing the CSV's

[Fazza]

Just finished setting up Windows Failover Cluster on Server 2022.

 

I'm using SCVMM to migrate the VMs from our current hypervisors (Hyper-V) to our new Windows Failover Cluster.

 

I have a SAN with 2 volumes configured on it, one is 18TB and the other is 9TB.

 

I've migrated successfully over a dozen of our smaller servers (no more than 200GB) without a problem. Not it's time to move a couple of our large file servers. One of the File Services is about 852GB in size so should happily fit on either of the Cluster Shared Volumes (18TB or 9TB).

 

When I try to migrate the VM to the Cluster it doesn't appear to see the free space on the cluster shared volumes and reports that there is not enough disk space (it looks like it's only looking at the free space on the C: drive).

 

 

How do I get SCVMM to see the 18TB and 9TB worth of space available so I can successfully migrate our file servers to our shiny Windows Failover Cluster that has 27TB of space but wont see it?!

 

Thanks.
