卸载挂载的盘提示如下:
[root@moneyslow.com 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))
[root@moneyslow.com 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.

复制代码
[root@moneyslow.com 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
如果还是不行,还可以强行解除挂载
umount -l /mnt/cdrom
强行解除挂载
[root@moneyslow.com yum.repos.d]# ps aux |grep 1338 //查看占用进程
