在我们进行远程文件操作的时候,我们经常会出现文件服务出现卸载掉哦情况。例如
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:
1.查找使用这个文件的进程和命令,具体的操作代码
[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.然后执行ps命令可以查找执行此进程的命令
[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
[root@localhost ~]# kill -9 18841
4.然后卸载相关挂载
[root@localhost ~]# umount /mnt/net1
5.然后可以在通过mount命令进行查看。
