Freien Speicherplatz auf Laufwerk über Lotusscript ermitteln

[schroederk]

Hallo,

ich würde gerne über Lotusscript den freien Speicherplatz der Laufwerke des Servers ermitteln.
Da es ja hierfür keine direkte Möglichkeit gibt, dachte ich an die Windows API.

Code

Declare Function GetDiskFreeSpace Lib "Kernel32" Alias _
"GetDiskFreeSpaceA" (ByVal lpRootPathName As String, _
lpSectorsPerCluster As Long, lpBytesPerSector As Long, _
lpNumberOfFreeClusters As Long, lpTtoalNumberOfClusters _
As Long) As Long
 
Sub Initialize
	Dim drv As String
	Dim ret As Long
	Dim sectors As Long
	Dim bytes As Long
	Dim free As Long
	Dim total As Long
 
	drv = "C:\"
	ret = GetDiskFreeSpace(drv, sectors, bytes, free, total)
 
	MessageBox "S=" & sectors & " B=" & bytes & " F=" & free
End Sub

Für Laufwerk C:\ bekomme ich einen Wert zurück: S=8 N=512 F=36.264.391
Meinem Verständnis nach sollte sectors * bytes * free den freien Platz ermitteln.
Das Betriebssystem selber zeigt mir an: 37.992.173.568
Ich hab keinen Schimmer, was das also für Werte sind, bzw. wie ich auf den tatsächlichen freien Platz kommen kann. 

Wenn ich als Laufwerk D:\ angebe, dann gibt mir die Funktion überall 0 zurück? 
Wieso funktioniert die Funktion nur bei C:\ ?

Weiß jemand, wie ich die korrekten Werte für alle lokalen Laufwerke ermitteln kann?

Hier eine Klasse, die ich irgendwann 2006 mal geschrieben habe ( funktioniert auch noch unter Win 10 , 2012, 2016 ... )

mit

Code

Sub Click(Source As Button)
	Dim strComputer As String
	Dim i As Integer
	strComputer = "192.168.178.33"
	Dim HDD As Variant	
	
	Set HDD = New HDD(strComputer)
	For i = 0 To ( HDD.TOTALNUMBERS -1 )
		Msgbox _
		"Cyl: " & HDD.CYLINDER(i) &_
		" Heads: " & HDD.HEADS(i) & _
		" Sectors: " & HDD.SECTOR(i) & _
		" Tracks: " & HDD.TRACKS(i) &_
		" TracksPerCylinder: " & HDD.TRACKSPERCYLINDER(i)
	Next
	For i = 0 To ( HDD.TOTALNUMBERS -1 )
		Msgbox HDD.MODEL(i)
	Next
End Sub

bekommst du die Informationen für ALLE Laufwerke eines Rechners ( lokal oder remote )

Herzlichen Dank für Dein Script. Das werde ich in jedem Fall ausprobieren.

Hallo K.,

ich habe hierzu ein Programmdokument auf den zugehörigen Servern erstellt (Batchdatei-Aufruf), das per Befehlszeile eine dir-Eingabeaufforderung auf den entsprechenden Laufwerken in jeweils eine Datei umgeleitet hat (z.B. dir c:\ > c:\temp\laufwerkc.txt). Dann habe ich diese Dateien per Script ausgewertet (letzte Zeile der Datei vor Bytes frei).

Ja, klar ist das von Eknori chicer, komplexer, allgemeingültiger etc., eben einfach eknoriger. Aber meins tut's auch. Ist halt nur so 'ne Idee von mir.

Liebe Grüße
René

Es geht auch kürzer
Hab mir ein Script geschrieben um mir eine Nachricht zukommen zu lassen, wenn der Platz am Server zu klein wird - vielleicht hilft es Dir

Sub Initialize
   
   Dim session As New NotesSession
   Dim db As NotesDatabase   
   Dim objFSO As Variant
   Dim colDrives As Variant
   Dim memo As NotesDocument
   
   Set objFSO = CreateObject("Scripting.FileSystemObject")
   Set colDrives = objFSO.Drives
   Forall objDrive In colDrives
      
      If Cstr(objDrive.DriveLetter) = gNDparam.getItemValue("hddDriveLetter")(0) Then
         If Cdbl(objDrive.AvailableSpace) < Cdbl(gNDparam.getItemValue("hddLimit")(0)) Then
            Set db = session.CurrentDatabase
            Set memo = db.CreateDocument
            memo.form = "Memo"
            memo.subject = "HDD-Limit am Server " + db.server + " erreicht. Bitte alte Daten entfernen"

Das finde ich an meinem Job so spannend. Es gibt nicht nur einen, den einen, richtigen Weg. Es gibt viele Möglichkeiten, ein Problem zu lösen.
