Please help me , when I try to increase the partition size in LVM, but when I try it doesn’t work, I do the following:

  df -h

Filesystem                         Size  Used Avail Use% Mounted on
udev                               3.9G     0  3.9G   0% /dev
tmpfs                              795M  1.3M  794M   1% /run
/dev/mapper/ubuntu--vg-ubuntu--lv  244G  113G  121G  49% /


sudo lvextend --resizefs -l +100%FREE ubuntu-vg/ubuntu-lv


Size of logical volume ubuntu-vg/ubuntu-lv unchanged from <248.00 GiB (63487 extents).
  Logical volume ubuntu-vg/ubuntu-lv successfully resized.
resize2fs 1.45.5 (07-Jan-2020)
The filesystem is already 65010688 (4k) blocks long.  Nothing to do!


df -h

  VG UUID               Vl06pF-MGCJ-WFC9-Vz45-UCuf-EsEI-9IFP8R

Afterwards everything remains the same. I don't understand what I'm doing wrong. More precisely, I do not have a complete understanding.

The LV is already at its maximum size of approximately 247 GiB and there are no more extents available to allocate:

vgdisplay
--- Volume group ---
VG Name               ubuntu-vg
...
VG Size               <248.00 GiB
PE Size               4.00 MiB
Total PE              63487
Alloc PE / Size       63487 / <248.00 GiB
Free  PE / Size       0 / 0

There is a little over half of the filesystem it contains still unused:

df -h
Filesystem                         Size  Used Avail Use% Mounted on
/dev/mapper/ubuntu--vg-ubuntu--lv  244G  113G  121G  49% /

What a fool I am. For some reason I thought that this was all available, and not how much was left. Such thoughts arose due to an error that there is not enough disk space. But actually everything is fine. Sorry for the nonsense(
