Voici un petit script Powershell permettant de récupérer la taille d’un ou plusieurs share.
Ce script peut être appelé de deux manières :
- sans arguments : le script va chercher un fichier texte dans le répertoire d’exécution pour passer sur TOUS les répertoires indiqués dans le fichier (un partage par ligne) ; le but est donc de renseigner tous les partages pour lesquels on souhaite connaître la volumétrie dans le fichier. Le script retourne ensuite un fichier CSV :
- avec des arguments : en donnant en argument d’exécution du script le serveur et le partage, on récupère la taille dans la console directement :
param([string]$shareHost, [string]$shareName)
function folderSize()
{
param($path)
try {
$byteSize = (Get-ChildItem -path "$path" -Recurse -ErrorAction SilentlyContinue | Measure-Object Length -sum).Sum
if ($byteSize.ToString().Length -lt 4) { return "$byteSize B." }
if ($byteSize.ToString().Length -ge 4 -and $byteSize.ToString().Length -lt 7) { $kbSize = [math]::Round($byteSize/1024,1) ; return "$kbSize KB." }
if ($byteSize.ToString().Length -ge 7 -and $byteSize.ToString().Length -lt 10) { $mbSize = [math]::Round($byteSize/1048576,1) ; return "$mbSize MB." }
if ($byteSize.ToString().Length -ge 10 -and $byteSize.ToString().Length -lt 13) { $gbSize = [math]::Round($byteSize/1073741824,1) ; return "$gbSize GB." }
if ($byteSize.ToString().Length -ge 13) { $tbSize = [math]::Round($byteSize/1099511627776,2) ; return "$tbSize TB." }
}
catch { return "Share doesn't exist or is unreachable or you don't have the required privileges." }
}
