#查看虚拟机文件系统的磁盘空间占用情况
[user@fly-vm ~]$ df -h
Filesystem Size Used Avail Use% Mounted on
udev 1.9G 0 1.9G 0% /dev
tmpfs 393M 24M 369M 6% /run
/dev/sda1 49G 28G 19G 60% /
tmpfs 2.0G 216K 2.0G 1% /dev/shm
tmpfs 5.0M 4.0K 5.0M 1% /run/lock
tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup
tmpfs 393M 52K 393M 1% /run/user/1001
查看，可知总的磁盘空间为
50GB，已经使用了60%。担心未来可能需要更多的空间，决定扩容到80GB；
