CentOS6.4x84挂载U盘
root用户登录
1、
查看磁盘情况:
fdisk -l
信息如下:
[root@CentOS6 ~]# fdisk -l Disk /dev/sda: 128.8 GB, 128849018880 bytes 255 heads, 63 sectors/track, 15665 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000d5240 Device Boot Start End Blocks Id System /dev/sda1 * 1 64 512000 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 64 15666 125316096 8e Linux LVM Disk /dev/mapper/vg_centos6-lv_root: 53.7 GB, 53687091200 bytes 255 heads, 63 sectors/track, 6527 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/vg_centos6-lv_swap: 2113 MB, 2113929216 bytes 255 heads, 63 sectors/track, 257 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sdb: 15.9 GB, 15943233536 bytes 82 heads, 55 sectors/track, 6904 cylinders Units = cylinders of 4510 * 512 = 2309120 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 * 1 6905 15569532+ c W95 FAT32 (LBA) Disk /dev/mapper/vg_centos6-lv_home: 72.5 GB, 72519516160 bytes 255 heads, 63 sectors/track, 8816 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 [root@CentOS6 ~]#
如果看不到U盘的话,尝试 加载USB模块 "modprobe usb-storage" 。
2、
创建一个文件夹"/mnt/usb_zz"
3、
挂载U盘:
mount -t vfat /dev/sdb1 /mnt/usb_zz
ZC:(1)、这里,没有"-t vfat"的话,会提示 指定文件系统。(2)、fat32 的文件系统 对应的参数就是 vfat。
4、
卸载U盘
umount /mnt/usb_zz
执行umount命令卸载U盘时,报如下错误“device is busy”,
可以用参数l解决问题:(ZC: 这里是小写的字母L)
umount -f /mnt/usb_zz
umount -l /mnt/usb_zz
也可以用fuser命令解决问题。
