Descrizione

Il cmdlet Remove-AzDataLakeGen2AclRecursive rimuove l'ACL in modo ricorsivo nel percorso specificato. Le voci ACL nell'ACL originale, che hanno lo stesso AccessControlType, DefaultScope ed EntityId con voci ACL di input (anche con autorizzazioni diverse) verranno rimosse.

Esempio

Esempio 1: Rimuovere l'ACL in modo ricorsivo in una directiry radice del file system

$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -EntityId $id -Permission r-x -DefaultScope
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -EntityId $id -Permission r-x -InputObject $acl
Remove-AzDataLakeGen2AclRecursive -FileSystem "filesystem1" -Acl $acl -Context $ctx
WARNING: To find the ACL Entry to remove, will only compare AccessControlType, DefaultScope and EntityId, will omit Permission.

FailedEntries                   : 
TotalDirectoriesSuccessfulCount : 7
TotalFilesSuccessfulCount       : 5
TotalFailureCount               : 0
ContinuationToken               :

Questo comando crea innanzitutto un oggetto ACL con 2 voci acl, quindi rimuove l'ACL in modo ricorsivo in una directory radice di un file system.

Esempio 2: Rimuovere ACL in modo ricorsivo in una directory

$result = Remove-AzDataLakeGen2AclRecursive -FileSystem "filesystem1" -Path "dir1" -Acl $acl  -Context $ctx
WARNING: To find the ACL Entry to remove, will only compare AccessControlType, DefaultScope and EntityId, will omit Permission.

$result

TotalDirectoriesSuccessfulCount : 500
TotalFilesSuccessfulCount       : 2500
TotalFailureCount               : 1

WARNING: To find the ACL Entry to remove, will only compare AccessControlType, DefaultScope and EntityId, will omit Permission.

$result

FailedEntries                   : 
TotalDirectoriesSuccessfulCount : 100
TotalFilesSuccessfulCount       : 1000
TotalFailureCount               : 0
ContinuationToken               :

Questo comando rimuove prima L'ACL in modo ricorsivo in una directory e non è riuscito, quindi riprende con ContinuationToken dopo che l'utente corregge il file non riuscito.

Esempio 3: Rimuovere blocco ACL in modo ricorsivo per blocco

$token = $null
$TotalDirectoriesSuccess = 0
$TotalFilesSuccess = 0
$totalFailure = 0
$FailedEntries = New-Object System.Collections.Generic.List[System.Object]
do
{
    $result = Remove-AzDataLakeGen2AclRecursive -FileSystem "filesystem1" -Path "dir1" -Acl $acl  -BatchSize 1000 -MaxBatchCount 50 -ContinuationToken $token -Context $ctx

    # echo $result
    $TotalFilesSuccess += $result.TotalFilesSuccessfulCount
    $TotalDirectoriesSuccess += $result.TotalDirectoriesSuccessfulCount
    $totalFailure += $result.TotalFailureCount
    $FailedEntries += $result.FailedEntries
    $token = $result.ContinuationToken
}while (($token -ne $null) -and ($result.TotalFailureCount -eq 0))
echo ""
echo "[Result Summary]"
echo "TotalDirectoriesSuccessfulCount: `t$($TotalDirectoriesSuccess)"
echo "TotalFilesSuccessfulCount: `t`t`t$($TotalFilesSuccess)"
echo "TotalFailureCount: `t`t`t`t`t$($totalFailure)"
echo "ContinuationToken: `t`t`t`t`t$($token)"
echo "FailedEntries:"$($FailedEntries | ft)

Questo script rimuoverà l'ACL in modo ricorsivo nel blocco di directory per blocco, con dimensioni del blocco come BatchSize * MaxBatchCount. Le dimensioni del blocco sono pari a 50000 in questo script.

Esempio 4: Rimuovere ACL in modo ricorsivo in una directory e ContinueOnFailure, quindi riprendere da errori uno alla sola

$result = Remove-AzDataLakeGen2AclRecursive -FileSystem "filesystem1" -Path "dir1" -Acl $acl -ContinueOnFailure -Context $ctx

$result

FailedEntries                   : {dir0/dir1/file1, dir0/dir2/file4}
TotalDirectoriesSuccessfulCount : 100
TotalFilesSuccessfulCount       : 500
TotalFailureCount               : 2

# user need fix the failed item , then can resume with ContinuationToken

foreach ($path in $result.FailedEntries.Name)
        {
            # user code to fix failed entry in $path
            
            #set ACL again
            Remove-AzDataLakeGen2AclRecursive -FileSystem "filesystem1" -Path $path -Acl $acl -Context $ctx
        }

Questo comando rimuove prima L'ACL in modo ricorsivo in una directory con ContinueOnFailure e alcuni elementi non sono riusciti, quindi riprendono gli elementi non riusciti uno alla volta.
