増やしたい分だけ。

Ubuntu側の拡張

$ df -h

色々書いてあるけど重要なのはlvなんとかのとこ。 これがLVMパーティションなので拡張する

$ sudo parted -l

このコマンドでext4であること、ディスクサイズが64GBであることが確認できる 

$ growpart /dev/sda 3
$ lsblk

/dev/sda3自体は64GBになった
image

$ pvresize /dev/sda3
$ pvdisplay

物理ボリュームもリサイズ
image

$ sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv
$ sudo lvdisplay

次にLVMパーティションを最大サイズに拡張
image

$ resize2fs
$ df -h
