Aqui estão alguns comandos do powershell que me ajudaram a passar por isso. O comando que o Rikuto compartilhou faz parte da solução, mas eu tive que desligar o S2D para que o comando funcionasse.
#find out the unique id for your disk (look for the disk you just created by size)
Get-PhysicalDisk | Select-Object -Property FriendlyName, uniqueID, Size
#assign the UID of the desired disk to a variable
$DiskUID = "<unique disk ID>"
#disable S2D so that disk can be freed from pool and set disk to not be claimed by pool
Disable-ClusterStorageSpacesDirect
Set-ClusterStorageSpacesDirectDisk -CanBeClaimed:$false -PhysicalDiskIds $DiskUID
#re-enable S2D and wait for your clustered volume to become healthy
Enable-ClusterStorageSpacesDirect
Espero que isso ajude.
