but when I try to Create Virtual Server,I got a message below:

Howdy,

Hmm, that’s an unusual error!

Do you by chance have SELinux enabled? You can determine that by running the command “sestatus”.

Also, are there any special file attributes setup on your /etc/gshadow file? You can determine that by running “lsattr /etc/gshadow”.

Thanks,

Thank you for your reply.
The SELinux is desabled.
I have result like bellow:

[root@host ~]# sestatus
SELinux status: disabled
[root@host ~]# lsattr /etc/gshadow
----i-------- /etc/gshadow

Is there some something wrong ? And How can I fix ?

Thanks again.

It looks like your gshadow file has the “immutable” attribute set, which means that even root isn’t allowed to modify that file. I have no idea how that might have happened, and that’s certainly not a default.

However, to fix it, you can run this command:

chattr -i /etc/gshadow
