Increased disk size. How to use the new location in Debian?

Question

linux

On a virtual machine (from selectel.ru) I have Debian mini. Initially took 1 GB. space, but over time it became not enough. In the settings of the virtual machine, I increased the hard disk to 2 GB.
Can you please tell me how to start using this place in Debian now? I'm weak in nix.

Answer 1

First, format the new partition with the mkfs -t /dev/blablabla command,
and then mount

Answer 2

As far as I remember, I solved a similar problem with a single
resize2fs command
