How do I get disk space statistics for a clustered disk

I have a working program that retrieves information of disk such as FreeSpace, TotalSpace etc from a remote server. I have a problem however that i cannot get these stattistics for all Clustered Disks mapped on onto the server. Th query only returns information for the Local Disk (Logical Disk).

I am able to get disk space sizes as below :

<pre>public List<Disk> GetEnvironmentStatistics()
        {
            var serverIP = Convert.ToString(System.Web.HttpContext.Current.Session["ServerIP"]); 
         
            List<Disk> diskinfo = new List<Disk>();

            //Add System.Management to access these utilities
            ConnectionOptions options = new ConnectionOptions
            {

                Username = Convert.ToString(System.Web.HttpContext.Current.Session["Username"]),
                Password = Convert.ToString(System.Web.HttpContext.Current.Session["Password"]),
                Authority = Convert.ToString(System.Web.HttpContext.Current.Session["Authority"]),
            };

            //root - root of the tree, cimv2 - version           
            ManagementScope scope = new ManagementScope("\\\\" + serverIP + "\\root\\CIMV2", options);
            scope.Connect();

            SelectQuery query = new SelectQuery("Select * from Win32_LogicalDisk");
            ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
            ManagementObjectCollection queryCollection = searcher.Get();

           
                foreach (ManagementObject mo in queryCollection)
                {
                    Disk disk = new Disk();
                    disk.DiskName = mo["Name"].ToString();                  
                    disk.DeviceId = mo["DeviceID"].ToString();
                    disk.SystemName = mo["SystemName"].ToString();

                    disk.FreeSpace = Convert.ToDecimal(mo["FreeSpace"]);
                    var formattedFreeSpace = Helpers.DiskSpaceInGigabytes(disk.FreeSpace ?? 0);
                    disk.FreeSpace = Decimal.Truncate(formattedFreeSpace);
                
                    disk.TotalSpace = Convert.ToDecimal(mo["Size"]);
                    var formattedTotalSpace = Helpers.DiskSpaceInGigabytes(disk.TotalSpace ?? 0);
                    disk.TotalSpace = Decimal.Truncate(formattedTotalSpace);
                   
                    disk.UsedSpace = disk.TotalSpace - disk.FreeSpace;
                    
                    var HDPercentageUsed = 100 - (100 * disk.FreeSpace / disk.TotalSpace);
                    disk.PercentageUsed = Convert.ToInt32(HDPercentageUsed);
                    diskinfo.Add(disk);
                }

              
                   
            return diskinfo;
        }

I have logged into the server and noted the other disks appear as Clustered Disk
.

What I have tried:

How do i get information about the space on the Clustered Disks using WMI. Is there a way to specify the type of Drive in WMI , in this case specifying that its a Clustered Disk and not Local Disk.. i would like to think if i can specify the drive type then i should also be able to get information for the Clustered Disks.

I have been looking at this https://www.avianwaves.com/Blog/ArticleID/178/PowerShell-WMI-Free-Disk-Space-from-a-Cluster-Shared-Volume-CSV-in-a-Windows-Failover-Cluster but it doesnt quite suit my requirements and its Powershell also .
