Disk resizing problem

Hello @Majed OMRI

I understand that you have extended disk from 32 GB to 64GB in Azure Portal.
If your disk was not extended in OS , you need to resize the disk partition from 32 GB to 64GB in Ubuntu OS directly.
Steps to increase disk in Ubuntu:

Login to Your Linux VM and check space on disks

df -h  

In Ubuntu you will see partition with 32GB size (For example /dev/sda1)

Change partition:

sudo fdisk /dev/sda  

Press u to change the units to sectors.

Press p to list the partitions details. The most important information is the starting sector (e.g. 2048).

Next step is to delete the partition (it will not delete Your data, it will only alter the partition table).
Press d and select the partition (if it’s only one partition, it will be selected automatically).

Press n and next press p to create a primary partition.
Press 1 or 2 to create first or second partition (depends on which partition we deleted). Next, enter the same value for starting sector from step where we have been printing an information about partitions. To end accept the default end sector to use the entire disk.

Write the partitions pressing w. If there will be some error, just ignore it - it's OK.
Reboot

sudo reboot  

Resize the filesystem

sudo resize2fs /dev/sdaX  

Where X is resized partition's number. This operation can take a long time, so don't be nervous.
Verify

df -h

I solved that with

sudo parted -l

and fix option
