新建一个文件夹，作为此处模拟的块设备的挂载点
root@linuxidc:/source/workplace/test/sbull_linuxidc# ls /mnt/
hgfs initrd
root@linuxidc:/source/workplace/test/sbull_linuxidc# mkdir /mnt/sbulla1
挂载
root@linuxidc:/source/workplace/test/sbull_linuxidc# mount /dev/sbulla1 /mnt/sbulla1
进入目录，新建一个文件，测试一下
root@linuxidc:/source/workplace/test/sbull_linuxidc# cd /mnt/sbulla1/
root@linuxidc:/mnt/sbulla1# ls
lost+found
root@linuxidc:/mnt/sbulla1# echo hi > hello.c
root@linuxidc:/mnt/sbulla1# ls
hello.c lost+found
root@linuxidc:/mnt/sbulla1# cat hello.c
hi
root@linuxidc:/mnt/sbulla1#
