    当mount挂载了文件系统之后,卸载的时候

    umount遇到 device is busy


    [root@linusfay ~]# umount /mnt/share
    umount: /mnt/share: device is busy
    umount: /mnt/share: device is busy

    原因:当任何目录有 mount, 然后有程序使用/挂在那个目录上的话, 就没有办法 umount 掉, 於 umount 时会出现 Device is busy 的错误。

    类似的解决办法:

    1、找哪个进程在使用该挂载目录,然后杀掉该进程,卸载目录。

    [root@linusfay share]# fuser -m /mnt/share
    /mnt/share:           5161c


    [root@linusfay share]# ps aux |grep 5161 |grep -v grep
    root      5161  0.0  0.0  66076  1520 pts/3    Ss   04:53   0:00 bash

    [root@linusfay share]#kill  -9   5161

    [root@linusfay ~]# umount share1

    2、mount  -l  /mnt/share  当需卸载文件系统的引用不繁忙时直接卸载。

    [root@linusfay share]# umount share1
    umount: /mnt/share: device is busy
    umount: /mnt/share: device is busy

    [root@linusfay share]# umount  -l share1


    查看是否完成卸载:

    [root@linusfay share]# df -h
    Filesystem            Size  Used Avail Use% Mounted on
    /dev/mapper/VolGroup00-LogVol00
                           36G   14G   21G  40% /
    /dev/sda1              99M   23M   71M  25% /boot
    tmpfs                 765M  364M  401M  48% /dev/shm


    --没有看到  share1目录umount  -l share1已经完成卸载

  • [root@KMVS-CENTOS cms]# umount /www/pic umount.nfs: /www/pic: device is busy umount.nfs: /www/pic: device is busy 解决方法:强制卸载 [root@KMVS-CENTOS cms]# fuser -m -v /www/pic/

    [root@KMVS-CENTOS cms]# umount /www/pic

    umount.nfs: /www/pic: device is busy

    umount.nfs: /www/pic: device is busy


    解决方法:强制卸载

    [root@KMVS-CENTOS cms]# fuser -m -v /www/pic/

                        用户     进程号 权限   命令

    /www/pic/:           root        600 ..c.. bash
                         root       1740 ..c.. bash

    [root@KMVS-CENTOS cms]# kill -9 600
    [root@KMVS-CENTOS cms]# kill -9 1740

    小结:

    -v 表示 verbose 模式。进程以 ps 的方式显示,包括 PID、USER、COMMAND、ACCESS 字段。
    -m 表示指定文件所在的文件系统或者块设备(处于 mount 状态)。所有访问该文件系统的进程都被列出。
