+In the case of expanding a data disk when there are several data disks present on the VM, it may be difficult to relate the Azure LUNs to the Linux devices.  If the OS disk needs expansion, it is clearly labeled in the Azure portal as the OS disk.
 
 Start by identifying the relationship between disk utilization, mount point, and device, with the ```df``` command.

-Here we can see, for example, the `/opt/db/data` filesystem is nearly full, and is located on the `/dev/sdd1` partition.  The output of `df` will show the device path regardless of whether the disk is mounted by device path or the (preferred) UUID in the fstab.  Also take note of the Type column, indicating the format of the filesystem.  This will be important later.

 ### Detecting a changed disk size
 
-If a data disk was expanded without downtime using the procedure mentioned previously, the disk size won't be changed until the device is rescanned, which normally only happens during the boot process. This rescan can be called on-demand with the following procedure.  In this example we have detected using the methods in this document that the data disk is currently `/dev/sda` and has been resized from 256GB to 512GB.
