1. Challenge

   Create the Managed Disk.

   1. Log in to the Azure Portal.

   2. Click + Add and add search for/select Managed Disks. Select Create.

   3. Configure the Disk:

   • Ensure that Resource Group is set to your resource group (not empty).
   • Enter inventory-processing-output for the Disk name.
   • Select West US for the Region.
   • Click Change size. For Account type, select Standard SSD. Select 512 GiB.

   4. Review and create the disk. After a short time, your disk will be created.
2. Challenge

   Attach the Disk to the VM.

   1. Return to the resource group main page by clicking Home, then the resource group.

   2. Click the Virtual machine resource called lab-VM.

   3. Select Disks from the menu.

   4. Click + Add data disk.

   5. Click the Name dropdown and select inventory-processing-output.

   6. Click Save.

   After a few moments, the disk will be attached to the VM.

3. Challenge

   Mount the Disk to the VM file system.

   1. Log in to the VM in a terminal.

   2. Verify that the disk has been attached to the VM.

   dmesg | grep SCSI
   

   You should see a line that reads:

   [sdc] Attached SCSI disk
   

   This means the managed disk is called sdc.

   3. Format the new disk:

   sudo fdisk /dev/sdc
   

   4. Respond to the prompts like so:

   Command (m for help): n
   Partition type
      p   primary (0 primary, 0 extended, 4 free)
      e   extended (container for logical partitions)
   Select (default p): p
   Partition number (1-4, default 1):
   First sector (2048-1073741823, default 2048):
   Last sector, +sectors or +size{K,M,G,T,P} (2048-1073741823, default 1073741823):
   
   Created a new partition 1 of type 'Linux' and of size 512 GiB.
   
   Command (m for help): w
   The partition table has been altered.
   Calling ioctl() to re-read partition table.
   Syncing disks.
   

   5. Create a file system on the new partition. Note that it will take a few moments to finish building the file system:

   sudo mkfs -t ext4 /dev/sdc1
   

   6. Create the output directory:

   sudo mkdir /output
   

   7. Get the Disk's UUID. Copy the UUID value from the output:

   sudo -i blkid | grep sdc1
   

   8. Add the new disk to fstab so that it will be automatically mounted whenever the VM restarts:

   sudo vi /etc/fstab
   

   9. Add a new line to the file. Be sure to replace <your disk UUID> with the Disk UUID that was printed by the blkid command earlier:

   UUID=<your disk UUID>   /output   ext4   defaults,nofail   1   2
   

   10. Mount the new Disk immediately by reloading fstab:

   sudo mount -a
   

   11. Write some data to the disk to verify that it is working:

   echo "Hello, world!" | sudo tee -a /output/test.txt
   

   12. Read the data back from the disk:

   cat /output/test.txt
