linux7下使用命令useradd或adduser添加用户时出现以下错误提示:
useradd:unable to lock password file

pwunconv提示:can't lock passwd file

用户权限为root
passwd和shadow文件属性为640 试过改为744结果一样.

ps -ef |grep passwd
也没有发现相关进程.

IFree不为0

什么原因?如何解决,请大家帮帮忙!!

ooooooooooooooooooooooooops~~~~~~~~

i have similar pb like urs when i was trying to change my passwd  file.etc/passwd needs to be locked to access it(means that it should not be used by anybody else(or any other process)).Maybe you are familiar with the locks in /var/.So I ask you whether you were changing the password through the network or anything else was using it?
You can't use 640 coz if some user other than root try to access it he will be denied.
You can try 744 normally as it would not compromise your security.
if ur pb existing either that usually this lock file in /etc/ptmp.check it out and see if that file exists and is old.if someone else is making changes on ur system.u just have to wait and try again and u shoud get in~
