挂载U盘失败

~ # mount /dev/sda1 /mnt/udisk/
mount: mounting /dev/sda1 on /mnt/udisk/ failed: No such device or address
~ # mount /dev/sda /mnt/udisk/
mount: mounting /dev/sda on /mnt/udisk/ failed: Invalid argument

 

查看/dev

~ # ls /dev/
/dev中没有sdb1这个设备节点

 

手动创建节点

~ # mknod  /dev/sda1 b 8 1

 

挂载U盘

~ # mknod  /dev/sda1 b 8 1
~ # mount /dev/sda1 /mnt/udisk/
~ # ls /mnt/udisk/
 Linux

 

挂载U盘成功
