Linux掛載U盤步驟如下

1：將U盤插入USB接口，檢查是否插好

2：用fdisk命令檢查分區(qū)和USB設備信息

[root@wgods ~]# fdisk -l

Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 121601 976655610 8e Linux LVM

Disk /dev/sdb: 4012 MB, 4012900352 bytes
223 heads, 55 sectors/track, 639 cylinders
Units = cylinders of 12265 * 512 = 6279680 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 * 56 640 3580928 c W95 FAT32 (LBA)
Partition 1 has different physical/logical beginnings (non-Linux?):
phys=(42, 17, 40) logical=(55, 23, 1)
Partition 1 has different physical/logical endings:
phys=(487, 222, 55) logical=(639, 6, 31)

通過上面信息我們可以看出USB設備是FAT32格式的，標識為/dev/sdb1

[root@wgods ~]# fdisk -l | grep FAT32
/dev/sdb1 * 56 640 3580928 c W95 FAT32 (LBA)

3:在mnt目錄下先建立一個usb的目錄

[root@wgods ~]# cd /mnt/
[root@wgods mnt]# mkdir usb

4：掛載U盤
[root@wgods mnt]# mount -t vfat /dev/sdb1 /mnt/usb

掛載成功后，我們可以在/mount/usb下看到相關的內容。

5：卸載U盤

執(zhí)行umount命令卸載U盤時，報如下錯誤“device is busy”，可以用參數l解決問題。當然你也可以用fuser命令解決問題。如下所示

[root@wgods ~]# umount /mnt/usb
umount: /mnt/usb: device is busy
umount: /mnt/usb: device is busy

[root@wgods ~]# umount -f /mnt/usb
umount2: Device or resource busy
umount: /mnt/usb: device is busy
umount2: Device or resource busy
umount: /mnt/usb: device is busy

[root@wgods ~]# umount -l /mnt/usb

?

問題解決

---------------------------------------------------------------------------------

[root@wgods usb]# umount /mnt/usb
umount: /mnt/usb: device is busy
umount: /mnt/usb: device is busy
[root@wgods usb]# fuser -m /mnt/usb
/mnt/usb: 21123c 21158c 21180c 21182c 21223c
[root@wgods usb]# ps -auxw | grep 21123
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.7/FAQ

[root@wgods usb]# fuser -kvm /mnt/usb

root 21180 ..c.. sh
root 21182 ..c.. less
root 21223 ..c.. bash

[etl@wgods ~]$ umount /mnt/usb
umount: /mnt/usb is not in the fstab (and you are not root)
[etl@wgods ~]$ su - root
Password:?
[root@wgods ~]# umount /mnt/usb

?

6: 刪除usb目錄
[root@wgods ~]# umount -l /mnt/usb
[root@wgods ~]# rm -rf /mnt/usb

注意:有時候掛載時，中文的文件名和目錄名會出現亂碼，為了避免這種情況可以指定字符集，命令如下

[root@wgods ~]# mount -t vfat -o iocharset=utf8,codepage=uft8 /dev/sdb1 /mnt/usb

[root@wgods ~]# mount -t vfat -o iocharset=cp936,codepage=936 /dev/sdb1 /mnt/usb

注意：cp936是指簡體中文，cp950是指繁體中文。
