1) Login to the VM using SSH, we can check the size of the disk by using:
sudo dmesg | grep -i sda<\/code><\/p>\n\n\n\n

We should see something similar to the output below (assuming you changed the size to 100GB<\/strong> on the portal for the disk):
[    3.100914] sd 2:0:0:0: [sda] 209715200 512-byte logical blocks: (107 GB\/100 GiB<\/strong>)<\/p>\n\n\n\n

2) To proceed with the partition resize, we will use: sudo fdisk \/dev\/sda<\/code><\/p>\n\n\n\n

type: p<\/code>
this will show partition \/dev\/sda1<\/p>\n\n\n\n

type: d<\/code>
type: n<\/code> then p<\/code>, 1<\/code> (to recreate partition 1) you can accept the default values
NOTE:<\/strong> if you receive a message about deleting or keeping a signature on the disk, just answer N<\/code><\/strong>
type: w<\/code> (to save the new partition)
type: q<\/code> (to exit fdisk)
sudo reboot<\/code> (to reboot the VM so the partition is updated)<\/p>\n\n\n\n

3) To finalize the resize, after the reboot, execute the command: resize2fs \/dev\/sda1<\/code><\/p>\n\n\n\n

4) Use the command: df -h<\/code> to verify its size:
Filesystem Size Used Avail Use% Mounted on
\/dev\/sda1 99G 698M 94G 1% \/<\/p>\n\n\n\n
