5.3.11. Increase partition sizes on VPS

Attention!

Before performing any actions, be sure to create a backup of the server and save copies of all important data from the server to your PC.
Resizing partitions may be necessary when upgrading your VPS plan, as additional disk space appears on the system as unallocated space.

You can change the size of partitions using specialized graphical interface programs or via the console.
