New-DfsnRoot

Назначение: Windows 10 Technical Preview, Windows Server Technical Preview

Creates a DFS namespace.

Parameter Set: NewNamespace2
New-DfsnRoot [-TargetPath] <String> [-Type] <Type> {Standalone | DomainV1 | DomainV2} [[-EnableSiteCosting] <Boolean> ] [[-EnableInsiteReferrals] <Boolean> ] [[-EnableAccessBasedEnumeration] <Boolean> ] [[-EnableRootScalability] <Boolean> ] [[-EnableTargetFailback] <Boolean> ] [[-Description] <String> ] [[-State] <State> {Offline | Online} ] [[-TimeToLiveSec] <UInt32> ] [[-GrantAdminAccounts] <String[]> ] [[-TargetState] <State> {Offline | Online} ] [[-ReferralPriorityClass] <ReferralPriorityClass> {sitecostnormal | globalhigh | sitecosthigh | sitecostlow | globallow} ] [[-ReferralPriorityRank] <UInt32> ] [-CimSession <CimSession[]> ] [-Path <String> ] [-ThrottleLimit <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]

The New-DfsnRoot cmdlet creates a Distributed File System (DFS) namespace. Specify the root path and the root target path for the new namespace. You must also specify a type: stand-alone namespace, Windows 2000 Server mode (Domain v1) namespace, or Windows Server 2008 mode (Domain v2) namespace.

You can specify settings for the new namespace. You can use this cmdlet to enable or disable the following settings:

-- Site costing.
-- In-site referrals.
-- Access-based enumeration.
-- Root scalability.
-- Target failback.

You can also add a descriptive comment, select the state of the DFS namespace and DFS root target, and set the Time to Live (TTL) interval for referrals.

To manage the DFS namespace, you can grant permissions to users or user groups. Users who have these permissions can add, remove, and modify namespace folders and folder targets for the DFS namespace.

For more information about DFS namespaces, see Overview of DFS Namespaces (https://technet.microsoft.com/library/cc730736) on TechNet.

Запускает командлет в удаленном сеансе или на удаленном компьютере. Введите имя компьютера или объект сеанса, например выходные данные командлета New-CimSession или Get-CimSession. По умолчанию используется текущий сеанс на локальном компьютере.

Specifies a description for a DFS namespace.

Indicates whether a DFS namespace uses access-based enumeration. If this value is $True, a DFS namespace server shows a user only the files and folders that the user can access.

Indicates whether a DFS namespace server provides a client only with referrals that are in the same site as the client. If this value is $True, the DFS namespace server provides only in-site referrals. If this value is $False, the DFS namespace server provides in-site referrals first, then other referrals.

Indicates whether a DFS namespace uses root scalability mode. If this value is $True, DFS namespace servers connect to the nearest domain controllers for periodic namespace updates. If this value is $False, the servers connect to the primary domain controller (PDC) emulator.

Indicates whether a DFS namespace uses cost-based selection. If a client cannot access a folder target in-site, a DFS namespace server selects the least resource intensive alternative. If you provide a value of $True for this parameter, DFS namespace favors high-speed links over wide area network (WAN) links.

Indicates whether a DFS namespace uses target failback. If a client attempts to access a target on a server and that server is not available, the client fails over to another referral. If this value is $True, once the first server becomes available again, the client fails back to the first server. If this value is $False, the DFS namespace server does not require the client to fail back to the preferred server.

Specifies an array of accounts. This cmdlet grants management permissions for the DFS namespace to the users and user groups specifies. Users can add, remove, and modify namespace folders and folder targets.

Specifies a path for the root of a DFS namespace. This path must be unique. This path cannot be the name of an existing DFS namespace.

Specifies the target priority class for a DFS namespace root. Target priority offers you the ability to classify and rank in-site targets. You can specify targets to receive the highest or lowest preference, and you can divide the remaining targets based on their site cost for a DFS client to connect to them. Допустимые значения для этого параметра следующие:

-- GlobalHigh. The highest priority class for a DFS target. Targets assigned this class receive global preference.
-- SiteCostHigh. The highest site cost priority class for a DFS target. Targets assigned this class receive the most preference among targets of the same site cost for a given DFS client.
-- SiteCostNormal. The middle or normal site cost priority class for a DFS target.
-- SiteCostLow. The lowest site cost priority class for a DFS target. Targets assigned this class receive the least preference among targets of the same site cost for a given DFS client.
-- GlobalLow. The lowest level of priority class for a DFS target. Targets assigned this class receive the least preference globally.

Specifies the priority rank, as an integer, for a root target of the DFS namespace. Lower values have greater preference. A value of zero (0) is the greatest preference.

Specifies the state of the DFS namespace root. Допустимые значения для этого параметра следующие:

-- Online
-- Offline

Clients do not receive referrals for a DFS namespace folder that is offline. If you set a namespace root to a value of Offline, the entire namespace becomes inaccessible.

Specifies a path for a root target of the DFS namespace.

Specifies the state of the DFS namespace root target. Допустимые значения для этого параметра следующие:

-- Online
-- Offline

Clients do not receive referrals for a DFS namespace folder target that is Offline.

Указывает максимальное количество параллельных операций, которые можно установить для выполнения командлета. Если этот параметр опущен или введено значение 0, Windows PowerShell® вычисляет оптимальный предел регулирования для командлета по числу командлетов CIM, запущенных на компьютере. Предел регулирования применяется только к текущему командлету, а не сеансу или компьютеру.

Specifies a TTL interval, in seconds, for referrals. Clients store referrals to root targets for this length of time. The default TTL interval for root referrals is 300 seconds.

Specifies the type of a DFS namespace as a Type object. Допустимые значения для этого параметра следующие:

-- Standalone. Specifies a stand-alone namespace.
-- DomainV1. Specifies a Windows 2000 Server mode domain namespace.
-- DomainV2. Specifies a Windows Server 2008 mode domain namespace.

Выводит приглашение для подтверждения перед выполнением командлета.

Показывает, что произойдет при запуске командлета. Командлет не запущен.

Этот командлет поддерживает общие параметры: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer и -OutVariable. Дополнительные сведения см. в разделе  about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Возвращаемый тип — это тип объектов, возвращаемых командлетом.

• Microsoft.Management.Infrastructure.CimInstance#MSFT_DfsNamespace

This command creates a DFS namespace that has a root at the path \\Contoso\AccountingResources. The root target for the path is the shared folder \\Contoso-FS\AccountingResources. The namespace type is Windows Server 2008 mode, specified as a type of DomainV2.

PS C:\> New-DfsnRoot -TargetPath "\\Contoso-FS\AccountingResources" -Type DomainV2 -Path "\\Contoso\AccountingResources"

This command creates a stand-alone DFS namespace that has a root at path \\Contoso\Software that has a namespace root target pointing to \\Contoso-FS\Software. This namespace uses cost-based site selection.

PS C:\> New-DfsnRoot -TargetPath "\\Contoso-FS\Software" -Type Standalone -EnableSiteCosting -Path "\\Contoso\Software"
