Azure Blob Container Storage Operation Notes

teststorage51sec is storage account name

testcontainer2 is container name

Download an Archived file will be failed, but hot/cool will be ok. Cool download has no delay based on testing.

Change access layer for archive file. It is dehydrate process. 

You can choose to upload to a new folder to create a folder under Blob container when uploading files. You also can choose multiple files to upload at one time. 

Access Blob Storage Using Linux

Mounting on Linux is simple, but you’ll need to have an NFS client install first. Some distros have this automatically installed, but others will need to install it.

Once it’s installed, create a mountpoint with mkdir. You may need sudo if you aren’t a root user or don’t have permissions.

After creating the mountpoint, mount the Storage Account with the mount command.

On your VM, install client for NFS.

You will need to enable write access to the NFS share by creating two registry settings. You can do this by launching PowerShell and running the following two commands. Once this is done, you need to reboot or restart the NFS service. Failed to do this step, you will only be able to mount the NFS container, but not able to access it. It will show you error to say no permission.

New-ItemProperty -Path HKLM:/SOFTWARE/Microsoft/ClientForNFS/CurrentVersion/Default -Name AnonymousUid -PropertyType DWord -Value 0

New-ItemProperty -Path HKLM:/SOFTWARE/Microsoft/ClientForNFS/CurrentVersion/Default -Name AnonymousGid -PropertyType DWord -Value 0

Restart client VM.

The command completed successfully.

Performance:

The uploading speed is about 120Mbps from local to mounted NFS share. 

But when using Azure Storage Explorer, it can reach around 430Mbps.

Automatically Mount Local Drive to the Shared Server Folder upon System Startup

The next step is to automatically mount the shared folder in the Shared Server to your local drive upon system startup.

Create a Script

1. Create a batch file and put it in C:/mount.bat.

2. Open the file in a text editor and enter the following command(s) that mounts the sessions-storage or manager-storage folder in the shared server, whose IP address is 10.0.10.230, This folder is configured when setting up your Shared Server Directory to a local drive name S:

   Examples:

   mount -o fileaccess=777 10.0.10.230:/sessions-storage S: 

   mount -o fileaccess=777 10.0.10.230:/manager-storage S:

3. Save and close the file when you are done.

Create a Task to Execute the Batch File at System Startup

Next, you will create a task from the Task Scheduler that will execute your batch file at system startup.

1. Open the Task Scheduler application and select Create Basic Task in the right panel.

   

2. In Create a Basic Task screen, enter a name for our task, e.g. "Mount shared storage to S drive", then click Next.

   

3. In Task Trigger screen, select option 'When the computer starts', then click Next.

   

4. In Action screen, select the option Start a program and click Next.

   

5. In Start a Program screen, enter 'C:/mount.bat' to Program/script field then click Next.

   

6. In Summary screen, click Finish.

   

Edit the Task Properties

1. From Task Scheduler, select Task Scheduler Library folder in the left panel.

2. Look for your newly created task in the middle panel, and right click on it.

3. Select Properties in the popup menu.

   

4. In the Properties window, perform following actions:

   • Check the checkbox 'Run with highest privileges'

   • Click on 'Change User or Group...'

     

5. In the Select User or Group window, do the following:

• Enter 'system' to the field Enter the object to select

• Select Check Names

• Select OK 

  

6. The property window now will look like below. Click OK to finish setting up the task property.
