Azure Files Storage not accessible.

Hi,
As primary storage mean we are using Azure File storage (smb shares) for our application.
In the logs we find out that sometimes the shares aren't accessible. Over the last month it happened 9-10 times. In some cases it lasted up to 30 seconds. What can be reason for this? Is it because of preview state?
Thanks,
Kamil

Hi Kamil,
It might be due to the Preview Status or due to throttling as well.
To determine the exact cause, we would require more details which cannot be shared on a public forum.
Please raise a Technical Case for us to be able to assist you further.

A way to qeury Azure File Storage direct from Automation?

Hello.
I am trying to create a runbook that will query a list of files in Azure File Storage. This works fine from a powershell prompt on an Azure VM, but it appears the same methods in Azure Automation return different objects:
Sample code to just list the files in a given folder:
workflow Get-AzureFileStorageInfo
# Get Azure File Storage Name and Key
$storageName = Get-AutomationVariable -Name 'File Storage Name'
$storageKey = Get-AutomationVariable -Name 'File Storage Key'
# Get subscription and certificate information
$subscriptionName = Get-AutomationVariable -Name "Subscription Name"
$connection = Get-AutomationConnection -Name "Azure Connection"
$certificate = Get-AutomationCertificate -Name $connection.AutomationCertificateName
# Set the current subscription
Set-AzureSubscription -SubscriptionName $subscriptionName -SubscriptionId $connection.SubscriptionID -Certificate $certificate
Select-AzureSubscription -Current $subscriptionName
# get azure file storage context and share object
#$ctx = New-AzureStorageContext $StorageName $StorageKey
$s = Get-AzureStorageShare -Name $StorageName
# get list of files from Azure File Storage
Write-Output "Files in the DEMO folder..."
$DemoFiles = Get-AzureStorageFile -Share $s -Path "DEMO"
Write-Output $DemoFiles
I get this error when I run it:
6/02/2015 4:54:34 PM, Error: Get-AzureStorageShare : Cannot bind parameter 'Context'. Cannot convert the
"Microsoft.WindowsAzure.Commands.Common.Storage.AzureStorageContext" value of type
"Deserialized.Microsoft.WindowsAzure.Commands.Common.Storage.AzureStorageContext" to type
"Microsoft.WindowsAzure.Commands.Common.Storage.AzureStorageContext".

+
+ CategoryInfo : InvalidArgument: (:) [Get-AzureStorageShare], ParameterBindingException
+ FullyQualifiedErrorId :
CannotConvertArgumentNoMessage,Microsoft.WindowsAzure.Commands.Storage.File.Cmdlet.GetAzureStorageShare
I am obviously calling it wrong from Azure Automation. Is there sample code online somewhere that can demo the right way to call it? Thanks!
Matt

Perfect. That worked! Thanks!
For others who might be following this I made the change as shown below:
workflow Get-AzureFileStorageInfo
# Get Azure File Storage Name and Key
$storageName = Get-AutomationVariable -Name 'File Storage Name'
$storageKey = Get-AutomationVariable -Name 'File Storage Key'
# Get subscription and certificate information
$subscriptionName = Get-AutomationVariable -Name "Subscription Name"
$connection = Get-AutomationConnection -Name "Azure Connection"
$certificate = Get-AutomationCertificate -Name $connection.AutomationCertificateName
# Set the current subscription
Set-AzureSubscription -SubscriptionName $subscriptionName -SubscriptionId $connection.SubscriptionID -Certificate $certificate
Select-AzureSubscription -Current $subscriptionName
InlineScript {
# get azure file storage context and share object
$ctx = New-AzureStorageContext $Using:StorageName $Using:StorageKey
$s = Get-AzureStorageShare -Context $ctx
# get list of files from Azure
Write-Output "Files in the DEMO folder..."
$DemoFiles = Get-AzureStorageFile -Share $s -Path "DEMO"
Write-Output $DemoFiles

Updated to itunes 10.5 and Help files are not accessible

I have updated my itunes to 10.5 today but now the Help files are not accessible. I receive the following message - the request URL/itunes/win/10.5was not found on this server - Apache/2.2.3 (Oracle) Server at help.apple.com Port 80.

I have seen this before. You need to update the apps in your app store, and once they are updated, they will work again.

Can not get exclusive lock on the shared drive of Azure file storage

One of my application need exclusive access on the data folder where it writes the data.
I have setup data folder in Z drive which is shared drive of Azure File system.
The application is not able to get the exclusive access on the data folder and throws IO exception.
Is that not possible with shared drive of azure file system

Hi Subodh,
You could refer the following link for details on how pessimistic concurrency (Exclusive lock) managed in Azure Storage:
http://azure.microsoft.com/blog/2014/09/08/managing-concurrency-in-microsoft-azure-storage-2/
Please be advised that an Exclusive lock on an Azure File Share is not possible using REST Protocol and need to be done using the SMB Protocol.
You could refer the following link for details on how to manage SMB File locking:
https://msdn.microsoft.com/en-us/library/azure/dn194265.aspx?f=255&MSPPError=-2147217396
Hope this helps.

Azure File Storage - Creating a directory at the root level using REST

I have a Xamarin / iOS project, and looking to use Azure File Share as a back-end.
With that in mind, I'm playing around with the REST API and have generally got things working with (a) Blobs and (b) Account-level access to Files.
Specifically, I can successfully request a list of File Shares, so I have the general call structure worked out.
However, I'm stumped about the exact incantation necessary to create a new directory at the root level of a share.
I've tried the following three variants, but all result in Forbidden - Server failed to authenticate the request
request.Host: myaccount.file.core.windows.net
request.AbsolutePath: /myshare/subdirname1
request.Query: ?restype=directory
string to sign: PUT\n\n\n\n\n\n\n\n\n\n\n\nx-ms-date:Sun, 30 Nov 2014 16:07:25 GMT\nx-ms-version:2014-02-14\n/myaccount/myshare/subdirname1\nrestype:directory
request.Host: myaccount.file.core.windows.net
request.AbsolutePath: /myshare/subdirname1/
request.Query: ?restype=directory
string to sign: PUT\n\n\n\n\n\n\n\n\n\n\n\nx-ms-date:Sun, 30 Nov 2014 16:07:58 GMT\nx-ms-version:2014-02-14\n/myaccount/myshare/subdirname1/\nrestype:directory
request.Host: myaccount.file.core.windows.net
request.AbsolutePath: /myshare//subdirname1
request.Query: ?restype=directory
string to sign: PUT\n\n\n\n\n\n\n\n\n\n\n\nx-ms-date:Sun, 30 Nov 2014 16:06:16 GMT\nx-ms-version:2014-02-14\n/myaccount/myshare//subdirname1\nrestype:directory
I did note that trying to get the contents of an (empty) root directory doesn't behave quite the way I'd expect
request.Host: myaccount.file.core.windows.net
request.AbsolutePath: /myshare/
request.Query: ?resttype=directory&comp=list
string to sign: GET\n\n\n\n\n\n\n\n\n\n\n\nx-ms-date:Sun, 30 Nov 2014 16:23:17 GMT\nx-ms-version:2014-02-14\n/myaccount/myshare/\ncomp:list\nrestype:directory
Authenticates OK, but generates FAILURE BadRequest - The requested URI does not represent any resource on the server.
Which is different behaviour from pulling the list of blobs from an empty container (returns 200 with an empty xml list of blobs.
I've been through the File Service REST API document (dn167006) and found the azurestoragesamples on codeplex, but the former is unclear on working with the root level and the latter is from 2011 and predates File Storage.
Any insights?

First, thank you for the quick response and the suggestion about looking at the response content for the string to sign being used. I wasn't aware of that and obviously it's a fantastic resource for figuring this kind of stuff out.
And what it immediately revealed is it wasn't some subtle oddity in my construction of the STS, it was that I was doing a client.GetAsync(...) and not a client.PutAsync(...). DOH!
With that sorted, it was trivial to fix.
In terms of the List Directories and Files, though, there's still a problem.
FAILURE BadRequest - The requested URI does not represent any resource on the server.

The response XML is
<?xml version="1.0" encoding="utf-8"?>
<Error>

   <Message>The requested URI does not represent any resource on the server.\nRequestId:33d61aed-001a-0020-0cbd-51aea8000000\nTime:2014-11-30T18:40:04.9712797Z</Message>
   <UriPath>/myshare</UriPath>
</Error>
I originally thought it might be because the share was empty. However, I'm targeting the same share in which I created (apparently successfully) the subdirectory.
So I'm still confuzzled on that.

Move Excel files (400GB) from an external VPS service to Azure file storage

We are currently using an external VPS service to store 400GB Excel data in multiple files (approx 5000 files stored under 400 directories). Each directory refers to a region and user data within region.
Would like to copy all files from VPS to Azure storage account. Any thoughts on the best and most efficient way to accomplish this.
Thanks
Mike

Hi Manu
Thanks. Once the files are moved to Azure, how do I work on the excel files online? The idea here is to discontinue the third party VPS once all files are moved to Azure successfully.
If you read this old thread published in 2010, it looks like excel files cannot be read in Azure unless one uses OpenXML or OpenExcel.

Azure File Services not available in preview

I have created a high availability cloud service with 2 running instances and have encountered an issue with data that was being saved to the RoleEnvironment drive which is of course inaccessible if the user is moved to the other server by the load balancer.
I have therefore been investigating shared files between the instances where I could maintain the file structure of the uploaded zip file after unzipping it but the Azure File Service is not available in preview. Can I please request this for any of the two
subscriptions I belong to please

Hi Mohit (& Adi if this old issue never did get resolved for you),
First, Azure Files only work for new accounts created after your preview has been activated. The easiest ways to check if a new account has the file endpoint or not:
1) Current portal (manage.windowsazure.com): Click on the account, click "Dashboard", you should see Files under service with an end point (see example screenshot at end of message)
2) Alternatively, you can run from a cmd window: "nslookup <youraccountname>.file.core.windows.net". If your account has a file endpoint, the nslookup will resolve rather than saying "can't find the domain"
If you don't see the files end point on new accounts with the above method(s), please let us know and we can look further.
Thanks,

HELP (after XSAN controller crash files are not accessible)

Hi,
We are having a major issue with one of our XSAN setups. During my breah one of the Xsan controller crashed and burned. So a college that to resuce it by rebuilding the contoller and adding the Luns to the Xsan volume.
The files are not showing up but they are still there when doing a data recovery scan.
So where I Need help with (never done this before) to get the files back. What would be next steps to get the data back?

Azure Files is a Preview feature. Did you request and got access to it at the billing portal's Preview Features (https://account.windowsazure.com/PreviewFeatures)?
Also, you can now try creating the File share via the Preview Portal (https://portal.azure.com -> your storage account -> "File Shares").

How can I install downloads which are IN the download file, but not accessible or usable?

I often get the message to download a new flash player.
I click on the download button and nothing happens.
I tried disabling the firewall on Firefox. I still couldn't get the flash player to download.
Other, minor downloads have downloaded, and are in the download file. But they do not work, or are not installed, or somehow they are not usable or accessible to use.'''bold text'''

Music I purchased on I Tunes is not available when I open ITunes in I Movie. I Movie says those files are "protected" and not accessible. What does that mean and can I change them to "unprotected" so I can use them in IMovie?

Most of the music that I purchased on I Tunes I bought and downloaded on my old I Mac which I replaced with this I Mac about 9 months ago. When I"m using I Movie on this I Mac and try to open I Tunes tab in I Movie, most of the files are not accessible because I Movie says those fields are protected. What does that mean and can I change those files to unprotected so they show up in my music in IMovie?
This I Mac is OS X version 10.9.5 Maverick, 2.7GHz Intel Core 15 processor, 8GB 1600MHz DDR3 memory.

Caching for Azure Files

Hello,
New Azure Files service (currently in preview) is going to replace Cloud Drive feature in 2015.
I would like to know if there are any plans to provide a caching features (read / write) like the ones currently available for Cloud Drives.
The performance of Azure Files is currently limited by network speed restrictions based on VM size. Cloud Drives caching improves the performance and allows for achieving higher speeds than the network limit.
Depreciating Cloud Drives without proving a caching features means that the actual performance will drop for users not using X-Large instances, as the network speed limits for smaller sizes are below the limit of 480Mbps for Azure Files.
Jakub

hi Jakub,
Thanks for your posting!
Base on my experience, new Azure File service is to give us network-connected cloud storage that we can use seamlessly from inside a cloud service. So Azure File storage is like the VM local disk. Azure Cloud Drive allowed us to use the node’s local
temporary disk as a read cache. And the space for a drive’s is allocated form our web role or worker role temporary disk. About the network limit, it seems that Azure File Service used the Azure inside network. About Azure File service feature , I recommend
