POConsole Application to mount azure cloud drive
text
Body
copied!<p>I want to mount vhd from my private container. After google I get that it is only possible through .net. I am more of a JAVA person. I need a batch script or code in c# (So that I can get an exe file) which can automatically run at startup and mount vhd. So I decided to create a console app in order to get exe file.(I have very less knowledge c#/Visual studio) I am using following C# console application to do this.</p> <pre><code>using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using System.Net; using System.Threading; using Microsoft.WindowsAzure; using Microsoft.WindowsAzure.Diagnostics; using Microsoft.WindowsAzure.ServiceRuntime; using Microsoft.WindowsAzure.StorageClient; using Microsoft.WindowsAzure.Internal; namespace WorkerRole1 { public class WorkerRole : RoleEntryPoint { public override void Run() { // This is a sample worker implementation. Replace with your logic. Trace.WriteLine("WorkerRole1 entry point called", "Starting"); MountDrive(); //while (true) //{ // Thread.Sleep(10000); // Trace.WriteLine("Working", "Information"); //} } public override bool OnStart() { // Set the maximum number of concurrent connections ServicePointManager.DefaultConnectionLimit = 12; // For information on handling configuration changes // see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357. return base.OnStart(); } public void MountDrive() { string connectionStringSettingName = "DefaultEndpointsProtocol=http;AccountName=abc;AccountKey=xyz"; string azureContainerName = "vhds"; string vhdName = "myvhd.vhd"; CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionStringSettingName); //CloudStorageAccount storageAccount = CloudStorageAccount.DevelopmentStorageAccount; LocalResource localCache = RoleEnvironment.GetLocalResource("MyAzureDriveCache"); CloudDrive.InitializeCache(localCache.RootPath, localCache.MaximumSizeInMegabytes); Trace.WriteLine("RootPath =====" + localCache.RootPath); Trace.WriteLine("MaximumSizeInMegabytes =====" + localCache.MaximumSizeInMegabytes); // Just checking: make sure the container exists CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient(); blobClient.GetContainerReference(azureContainerName).CreateIfNotExist(); // Create cloud drive CloudDrive myCloudDrive = storageAccount.CreateCloudDrive( blobClient .GetContainerReference(azureContainerName) .GetPageBlobReference(vhdName) .Uri.ToString() ); Trace.WriteLine("Uri =====" + blobClient .GetContainerReference(azureContainerName) .GetPageBlobReference(vhdName) .Uri.ToString()); try { myCloudDrive.Create(1024); } catch (CloudDriveException ex) { // handle exception here // exception is also thrown if all is well but the drive already exists } string driveLetter = myCloudDrive.Mount(50, DriveMountOptions.Force);//Here It throws a Exception Trace.WriteLine("Drive =====" + driveLetter); for (int i = 0; i < 10; i++) { System.IO.File.WriteAllText(driveLetter + "\\" + i.ToString() + ".txt", "Test"); } } } } </code></pre> <p>But I keep getting exception <code>ERROR_DEVFABRIC_LOCAL_MOUNT_ONLY</code> at</p> <pre><code>string driveLetter = myCloudDrive.Mount(50, DriveMountOptions.Force); </code></pre> <p>Please tell me where am I going wrong?</p>
