I have a Ubuntu VM which has an unmanaged OS disk associated with it.
When we increased the size of the unmanaged OS disk from 30 GB to 50 GB(after deallocating the VM and increasing its size from the platform), the changes are not reflected in the filesystem /dev/sda1 and it is continuing to show the size of the partition to be 30 GB.
The increased 20 GB is shown as a free space when I RDP my VM.
Could anyone please help me with increasing the size of /dev/sda1 filesystem to 50 GB?
