S2D FaultDomainAwareness

We're setting up a 2 Node windows 2025 cluster with storage spaces direct

After creating the pool we created two virtual disk but see the following output

PS C:\WINDOWS\system32> Get-VirtualDisk | Format-List FriendlyName, Size, FaultDomainAwareness

FriendlyName         : ClusterPerformanceHistory
Size                 : 25769803776
FaultDomainAwareness : StorageScaleUnit

FriendlyName         : S2DVOL01
Size                 : 10995116277760
FaultDomainAwareness : 

FriendlyName         : S2DVOL02
Size                 : 10995116277760
FaultDomainAwareness : 

The FaultDomainAwareness is empty for the two virtual disk created on the storage pool which is configured like this

PS C:\WINDOWS\system32> Get-StoragePool –FriendlyName S2D-CLHV-001-Pool | Format-List FriendlyName, Size, FaultDomainAwarenessDefault

FriendlyName                : S2D-CLHV-001-Pool
Size                        : 57592038555648
FaultDomainAwarenessDefault : StorageScaleUnit

is there something wrong ?
