How to reduce SWAP size?

Question

linux

Hello.
There is a server with Debian just installed. The default SWAP size is 64G. It is necessary to reduce it to 4G, and combine the resulting space with a single logical partition. Actually, how can this be done without resorting to reinstalling the OS?
UPD EXT4 file system.

Answer 1

sudo swapoff /раздел
This will disable swap (preferably after a reboot when no programs are running).
Then run GParted or Gnome Disks, delete the swap partition and create a new one. Everything is simple, but if you have questions - write. This can be done on a live system.
If you want, you can expand the adjacent partition to the freed space. Some filesystems allow you to do this on the working system.
