How to rename your Azure subscriptions (tip)

When you have – like me – multiple Azure subscriptions and they all have the same subscription name (something like Visual Studio Enterprise – MPN for example ) it can be difficult to separate them.

I advice you to rename your subcriptions and give them a clear name to identify them.

This is how you can do that :

Go to your subscriptions pane in the Azure Portal and select your Azure subscription. Click overview and there you find the Rename button. Just choose to rename your subscription and after 10 minutes or so your Subscription has a new name!

How to add a data disk to your Azure Linux VM the right way

In this blogpost I shall describe how you add an extra data disk to your Linux VM running on Azure.

Step 1 Add a new disk to your Linux VM using the Azure Portal

Choose Add data disk to add an extra data disk and choose create data disk.

For demo purposes I quickly entered a default 20 GiB HD, nothing fancy 🙂

Don’t forget to save your changes!

Step 2 Connect to your VM using SSH or use the Serial console on your VM Pane in the Azure Portal

Use the following command to find all your data drives :

You see all your drives and the newly created drive

Here, sdc is the newly added disk. Let’s continue.

Now we have to partition the added disk using the following command :

Use the n command to add a new partition. In this example, we also choose p for a primary partition and accept the rest of the default values. The output will be similar to the following example:

Now we are going to write a partition (format) the newly added disk using the following command :

Now we are going to mount the formatted drive using the following commands :

You see your newly created disk :

To ensure that the drive is remounted automatically after a reboot, it must be added to the /etc/fstab file. Herefore I’m going to use the blkid utility:

2019-06-08 08_10_11-VMLIN01 - Serial console - Microsoft Azure ‎- Microsoft Edge.png

Now copy the UUID :

2019-06-08 08_11_15-VMLIN01 - Serial console - Microsoft Azure ‎- Microsoft Edge.png

Now we are going to add the UUID to the /etc/fstab. You can use VI or (like I prefer to use) nano.

The format is als follows :

UUID=<YourUUID> /<YourMountPoint> ext4 defaults,nofail 1 2

In my case it looks as follows :

2019-06-08 08_13_41-Microsoft Edge.png

Ok, let’s reboot the VM and check if the drive still exists..

Use the following command to check

As you can see the /MyDataDrive is still available after reboot.
