查看mount 信息web
mount -lbash
解除挂载的时候必定要退出到上一级目录,不然会失败spa
在咱们进行远程文件操做的时候,咱们常常会出现文件服务出现卸载掉哦状况。例如.net
umount /mnt/net1
umount: /mnt/net1: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
这种问题解决方案:orm
1、查找使用这个文件的进程和命令,具体的操做代码进程
[root@localhost ~]# lsof |grep /mnt/net1
lsof: WARNING: can't stat() cifs file system /mnt/net1
Output information may be incomplete.
bash 18841 root cwd unknown /mnt/net1/TDDOWNLOAD/软件 (stat: No such device)
2、而后执行ps命令能够查找执行此进程的命令ci
[root@localhost ~]# ps -ef|grep 18841
root 18841 18839 0 Nov29 pts/2 00:00:00 /bin/bash -l
root 29496 25604 0 16:26 pts/0 00:00:00 grep 18841
3、强行结束无关进程get
[root@localhost ~]# kill -9 18841
4、而后卸载相关挂载it
[root@localhost ~]# umount /mnt/net1io
5、而后能够在功过mount命令进行查看。
