Ubuntu 20 볼륨 그룹 디스크 공간 확장 문제

Ubuntu 20 운영 체제를 실행하는 서버는 Xen 가상화에서 확장할 수 없습니다.

250GB 디스크 공간을 265GB로 업데이트했는데, 명령 화면에서 아무리 해도 여유 공간이 전혀 표시되지 않습니다.

데이터를 삭제하거나 디스크를 포맷하지 않고 확장하는 방법.

lvextend -l +100%FREE /dev/mapper/vg0-lv--0
New size (63999 extents) matches existing size (63999 extents).

resize2fs /dev/vg0/lv-0
The filesystem is already 65534976 (4k) blocks long.  Nothing to do!
