VMware Fusion上のUbuntu 22.04 ファイルシステム拡張

① VMwareからハードディスクサイズ拡張

②　Ubuntuにハードディスクのサイズ変更を認識させる
$ sudo sh -c "echo 1 > /sys/class/block/sda/device/rescan"
$ df

Total PE 10110
Free PE 2
Allocated PE 10108

PV UUID 8aosOg-JAl0-7QfW-ZIom-I2Qr-kiAA-In2MKp

$ sudo pvresize /dev/sda3
Physical volume "/dev/sda3" changed
1 physical volume(s) resized or updated / 0 physical volume(s) not resized
$ sudo pvdisplay
--- Physical volume ---

$ sudo lvextend -l +100%FREE /dev/vgubuntu/root
Size of logical volume vgubuntu/root changed from <35.86 GiB (9179 extents) to 75.86 GiB (19421 extents).
Logical volume vgubuntu/root successfully resized.

⑦ ファイルシステム拡張
$ sudo resize2fs /dev/vgubuntu/root
resize2fs 1.46.5 (30-Dec-2021)
Filesystem at /dev/vgubuntu/root is mounted on /; on-line resizing required
old_desc_blocks = 5, new_desc_blocks = 10
The filesystem on /dev/vgubuntu/root is now 19887104 (4k) blocks long.
