Linux 挂载
[root@whp6 ~]# mount /dev/sdb5 /mnt/ [root@whp6 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 16G 2.1G 13G 14% / tmpfs 931M 0 931M 0% /dev/shm /dev/sda1 194M 28M 157M 16% /boot /dev/sdb5 2.0G 68M 1.9G 4% /mnt [root@whp6 ~]# df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sda3 ext4 16311208 2134352 13348288 14% / tmpfs tmpfs 953276 0 953276 0% /dev/shm /dev/sda1 ext4 198337 28320 159777 16% /boot /dev/sdb5 ext4 2071384 68632 1897528 4% /mnt [root@whp6 ~]#
备注：如果挂载到有文件的目录下 会遮挡原先文件（原文件会变成lost+found文件夹） 必须卸载挂载的硬盘 才能显示
# ls /home/ 1.txt 2 22 wanghaipeng whp # mount /dev/sdb1 /home/ # ls /home 这时看原来的文件就出来了 lost+found # umount /home # ls /home 1.txt 2 22 wanghaipeng whp #
