Re: reset root passwd

Hi Kranit,

1st of all your "LVM: /stand/rootconf is corrupted".
Post the output of
ll /sbin/passwd
ll /etc/passwd

Good judgment comes from experience and experience comes from bad judgment.

Re: reset root passwd

run fsck to fix file system consistency check and interactive repair & than mount /usr and try changing the password

also refer to below thread
Problems are common to all, but attitude makes the difference
Respected Contributor

Re: reset root passwd

For trusted systems,
#vi /tcb/files/auth/r/root

And change the line with u_pwd.


remove the encrypted string.



Re: reset root passwd

you are in single user mode .. and it seems /usr is not mounted ..
mount /usr

then run the command /bin/passwd

i think it would work then
