首先执行fdisk -l最底下

Device Start End Sectors Size Type

/dev/vda1 2048 6143 4096 2M BIOS boot

/dev/vda2 6144 104857566 104851423 50G EFI System

然后df指令:

Filesystem 1K-blocks Used Available Use% Mounted on

udev 487880 0 487880 0% /dev

tmpfs 101612 10936 90676 11% /run

/dev/vda2 51471976 5861852 43287236 12% /

tmpfs 508044 0 508044 0% /dev/shm

tmpfs 5120 0 5120 0% /run/lock

tmpfs 508044 0 508044 0% /sys/fs/cgroup

tmpfs 101612 0 101612 0% /run/user/0

udev:外设硬件设备映射目录

tmpfs ;临时目录

vda1表示:虚拟磁盘A分区1
