Today, on my Centos server I tried to add a user but got the following error:
-bash: /usr/sbin/useradd: Input/output error
How do i fix it?
Thanks
UPDATE:
var/log/messages is blank
df -h also gives me a the same input/output error:
-bash: /usr/sbin/df: Input/output error
'free' also gives me the same error:
-bash: /usr/sbin/free: Input/output error
Also, I cannot even shutdown the server ie: shutdown -s, gives me the same error.
Any ideas what might be the issue?
