Linux mount挂载和卸载硬盘脚本分享

Linux 挂载

[root@whp6 ~]# mount /dev/sdb5 /mnt/[root@whp6 ~]# df -hFilesystem 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 -TFilesystem 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 /home1.txt 2 22 wanghaipeng whp#

Linux umount 卸载

[root@whp6 /]# mount LABEL=wanghaipeng /home/whp/[root@whp6 /]# df -hFilesystem 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/dev/sdb1 2.0G 74M 1.9G 4% /home/whp[root@whp6 /]# umount -l /home/whp/[root@whp6 /]# df -hFilesystem 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 /]#
