[[email protected] yum.repos.d]# 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))

[[email protected] yum.repos.d]# 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 cases useful info about processes that use the device is found by lsof(8) or fuser(1)) umount2: 设备或资源忙

[[email protected] yum.repos.d]# fuser -m /mnt/cdrom//mnt/cdrom/: 1338c 5830c //占用进程pID

#fuser -m -k /mnt/cdrom/

 //或者查询后直接杀死进程 后面的2步就不需要执行了

[[email protected] yum.repos.d]# ps aux |grep 1338  //查看占用进程 root 1338 0.0 0.2 108292 1912 pts/2 Ss+ 14:27 0:00 -bash root 1423 0.0 0.1 103236 884 pts/1 S+ 14:49 0:00 grep 1338

 

[[email protected] yum.repos.d]# kill -9 1338  5830 // 或使用下面的一个一个杀死进程

[[email protected] yum.repos.d]# kill -9 1338
