umount: /home: device is busy

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。
[root@localhost home]# fuser -m /home
/home: 10278c 10279c 10280c 10281c 10282c 10295 10365 18222c

命令:kill -9 pid

另:

umount /home                      解挂

mount /dev/sda2 /home       挂载
