如何强制umount

1、查看挂载时

[root@server1 ~]# mount

/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)

proc on /proc type proc (rw)

sysfs on /sys type sysfs (rw)

devpts on /dev/pts type devpts (rw,gid=5,mode=620)

sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

/dev/sda1 on /boot type ext3 (rw)

tmpfs on /dev/shm type tmpfs (rw)

/home/rhel-server-5.4.iso on /mnt type iso9660 (rw,loop=/dev/loop0)

 

2、进行umount，但是提示device is busy，无法umount

[root@server1 ~]# umount /mnt

umount: /mnt: device is busy

umount: /mnt: device is busy

 

3、采用fuser来强制kill进程

[root@server1 ~]# fuser -km /mnt

/mnt: 124456c

 

4、进行正常umount

[root@server1 ~]#umount /mnt
