# umount /mnt/cdrom/ umount: /mnt/cdrom: device is busy. (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1)) # umount /mnt/cdrom/ -f //强制卸载也不行 umount2: 设备或资源忙 umount: /mnt/cdrom: device is busy. (In some ca

umount –a   报错device is busy如图 df    -h 执行 umount -l /dev/sdk1 fuser -m -v /cache10 再查看卸载了

转自:umount: /home: device is busy 取消挂载/home时出现umount: /home: device is busy,原因是因为有程序在使用/home目录,我们可以使用fuser查看那些程序的进程,然后杀掉就可以了.[[email protected] home]# fuser -m /home/home: 10278c 10279c 10280c 10281c 10282c 10295 10365 18222c 命令:kill -9 pid 另: umount

在Linux中,有时使用umount命令去卸载LV或文件时,可能出现umount: xxx: device is busy的情况,如下案例所示 [[email protected] u06]# vgdisplay -v VolGroup03     Using volume group(s) on command line     Finding volume group "VolGroup03"   --- Volume group ---   VG Name            

两步: 1.用fuser : fuser -k /data 2.umount /data 基本上可以搞定umount device busy忙的问题,当然最好是能确定该分区卸载不会有影响. 下面是fuser命令的一些参数解释: -k 杀死这些正在访问这些文件的进程.除非使用-signal修改信号,否则将发送SIGKILL信号. -i 交互模式 -l 列出所有已知的信号名称. -n 空间,选择不同的名字空间,可是file,udp,tcp.默认是file,也就是文件. -signal 指定发送的信号

#umount  /mnt/fourtumount: /mnt/fourt: device is busy.        (In some cases useful info about processes that use         the device is found by lsof(8) or fuser(1)) fuser 概述fuser命令是用来显示所有正在使用着指定的file, file system 或者 sockets的进程信息.例:#fuser -m -u /mnt/

执行umount 命令的时候出现 device is busy ,有人在使用这块磁盘 umount /dev/sde1 umount: /u01/app/oracle: device is busy umount: /u01/app/oracle: device is busy 使用fuser 命令查看哪个进程在使用 [[email protected] ~]# fuser -m /u01/app/oracle/ /u01/app/oracle/: 2636c 2694c [[email pro
