Subject: Manually resize partition and filesystem on a Contabo VPS after upgrading your storage

Good day from Singapore,

To extend your filesystem on a Contabo VPS after upgrading your storage, you must manually resize the partition and filesystem to utilize the new space. 
For Linux, use growpart and resize2fs (for ext4) or xfs_growfs (for XFS). 
For Windows, use the Disk Management tool to extend the volume.

As I am using AlmaLinux 9.7, the steps are as follows:

# dnf check-update

# dnf search cloud-utils

# dnf install cloud-utils-growpart

[root@ns1 ~]# fdisk -l /dev/sda
