A lease that has been broken can also be released. A client can immediately acquire a file share lease that has been released. For a break operation, proposed duration the lease should continue before it is broken, in seconds, between 0 and This break period is only used if it is shorter than the time remaining on the lease.
If longer, the time remaining on the lease is used. A new lease will not be available before the break period has expired, but the lease may be held for longer than the break period. If this header does not appear with a break operation, a fixed-duration lease breaks after the remaining lease period elapses, and an infinite lease breaks immediately. Required for acquire.
Specifies the duration of the lease, in seconds, or negative one -1 for a lease that never expires. A non-infinite lease can be between 15 and 60 seconds. A lease duration cannot be changed using renew or change. Optional for acquire , required for change. The Blob service returns Invalid request if the proposed lease ID is not in the correct format.
Specifies the origin from which the request is issued. The presence of this header results in cross-origin resource sharing headers on the response. Provides a client-generated, opaque value with a 1 KiB character limit that is recorded in the analytics logs when storage analytics logging is enabled. Using this header is highly recommended for correlating client-side activities with requests received by the server.
Returns the date and time the file share was last modified. The date format follows RFC Any operation that modifies the file share or its properties or metadata updates the last-modified time, including setting the file share's permissions. Operations on blobs do not affect the last-modified time of the file share.
When you request a lease, Azure Files returns a unique lease ID. While the lease is active, you must include the lease ID with any request to delete the file share, or to renew, change, or release the lease.
A successful renew operation also returns the lease ID for the active lease. Approximate time remaining in the lease period, in seconds. This header is returned only for a successful request to break the lease. If the break is immediate, 0 is returned. This header uniquely identifies the request that was made and can be used for troubleshooting the request.
This header returns the value of the origin request header in case of a match. Returns the list of response headers that are to be exposed to the client or issuer of the request. Returned if the request includes an Origin header and CORS is enabled with a matching rule that does not allow all origins. Azure file shares can be seamlessly used in Windows and Windows Server.
This article discusses the considerations for using an Azure file share with Windows and Windows Server. In order to use an Azure file share via the public endpoint outside of the Azure region it is hosted in, such as on-premises or in a different Azure region, the OS must support SMB 3. Older versions of Windows that support only SMB 2.
It is possible to purchase additional support for security updates only through the Extended Security Update ESU program. We strongly recommend migrating off of these operating systems. You can check if your firewall is blocking port with the Test-NetConnection cmdlet. To learn about ways to work around a blocked port, see the Cause 1: Port is blocked section of our Windows troubleshooting guide.
To use an Azure file share with Windows, you must either mount it, which means assigning it a drive letter or mount point path, or access it via its UNC path. This article uses the storage account key to access the file share. A storage account key is an administrator key for a storage account, including administrator permissions to all files and folders within the file share you're accessing, and for all file shares and other storage resources blobs, queues, tables, etc.
If this is not sufficient for your workload, Azure File Sync may be used, or you may use identity-based authentication over SMB. A common pattern for lifting and shifting line-of-business LOB applications that expect an SMB file share to Azure is to use an Azure file share as an alternative for running a dedicated Windows file server in an Azure VM.
One important consideration for successfully migrating a line-of-business application to use an Azure file share is that many line-of-business applications run under the context of a dedicated service account with limited system permissions rather than the VM's administrative account. The Azure portal provides you with a script that you can use to mount your file share directly to a host. We recommend using this provided script.
The first section to complete to create a storage account is labeled Basics. This contains all of the required fields to create a storage account. To create a GPv2 storage account, ensure the Performance radio button is set to Standard and the Account kind drop-down list is selected to StorageV2 general purpose v2. To create a FileStorage storage account, ensure the Performance radio button is set to Premium and Fileshares is selected in the Premium account type drop-down list. The networking section allows you to configure networking options.
These settings are optional for the creation of the storage account and can be configured later if desired. For more information on these options, see Azure Files networking considerations. The data protection section allows you to configure the soft-delete policy for Azure file shares in your storage account. Other settings related to soft-delete for blobs, containers, point-in-time restore for containers, versioning, and change feed apply only to Azure Blob storage.
Secure transfer required : This field indicates whether the storage account requires encryption in transit for communication to the storage account. If you require SMB 2. Large file shares : This field enables the storage account for file shares spanning up to TiB. Enabling this feature will limit your storage account to only locally redundant and zone redundant storage options.
Once a GPv2 storage account has been enabled for large file shares, you cannot disable the large file share capability. FileStorage storage accounts storage accounts for premium file shares do not have this option, as all premium file shares can scale up to TiB. The other settings that are available in the advanced tab hierarchical namespace for Azure Data Lake storage gen 2, default blob tier, NFSv3 for blob storage, etc.
These are optional and can be applied after storage account creation. This button won't be available if all of the required fields for a storage account are not filled.
This cmdlet has many options; only the required options are shown. To learn more about advanced options, see the New-AzStorageAccount cmdlet documentation. To simplify the creation of the storage account and subsequent file share, we will store several parameters in variables. You may replace the variable contents with whatever values you wish, however note that the storage account name must be globally unique. To create a storage account capable of storing standard Azure file shares, we will use the following command.
The -SkuName parameter relates to the type of redundancy desired; if you desire a geo-redundant or geo-zone-redundant storage account, you must also remove the -EnableLargeFileShare parameter. To create a storage account capable of storing premium Azure file shares, we will use the following command. Note that the -SkuName parameter has changed to include both Premium and the desired redundancy level of locally redundant LRS.
To create a storage account using the Azure CLI, we will use the az storage account create command. This command has many options; only the required options are shown. To learn more about the advanced options, see the az storage account create command documentation. The --sku parameter relates to the type of redundancy desired; if you desire a geo-redundant or geo-zone-redundant storage account, you must also remove the --enable-large-file-share parameter.
Note that the --sku parameter has changed to include both Premium and the desired redundancy level of locally redundant LRS. The --kind parameter is FileStorage instead of StorageV2 because premium file shares must be created in a FileStorage storage account instead of a GPv2 storage account.
Before you create an Azure file share on an existing account, you may want to enable it for large file shares if you haven't already. Open the Azure portal , and navigate to the storage account where you want to enable large file shares. Select Enabled on Large file shares , and then select Save. Select Share capacity then select TiB and Save. To enable large file shares on your existing account, use the following command.
Once you've created your storage account, all that is left is to create your file share. This process is mostly the same regardless of whether you're using a premium file share or a standard file share. You should consider the following differences. Standard file shares may be deployed into one of the standard tiers: transaction optimized default , hot, or cool.
This is a per file share tier that is not affected by the blob access tier of the storage account this property only relates to Azure Blob storage - it does not relate to Azure Files at all. You can change the tier of the share at any time after it has been deployed. Premium file shares cannot be directly converted to any standard tier. You can move file shares between tiers within GPv2 storage account types transaction optimized, hot, and cool.
