How to properly partition a disk?

Question

linux

I installed Ubuntu server 20.04 LTS on a server and did not immediately notice that I had incorrectly partitioned the disk. It so happened that the system itself believes that only part of the disk is available to it - 58 gigs out of 120.
What fdisk produces:

Disk /dev/sda: 119.25 GiB, 128035676160 bytes, 250069680 sectors
Disk model: HFS128G32TNF-N3A
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: FE70A862-2FA6-4C7C-96BA-C2061D589695

Device       Start       End   Sectors   Size Type
/dev/sda1     2048   2203647   2201600   1.1G EFI System
/dev/sda2  2203648   5349375   3145728   1.5G Linux filesystem
/dev/sda3  5349376 250066943 244717568 116.7G Linux filesystem


Disk /dev/mapper/ubuntu--vg-ubuntu--lv: 58.35 GiB, 62646124544 bytes, 122355712 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

Actually the question itself: is it possible to somehow return these gigs without reinstalling the system?
Thanks to all.
