/etc/passwd read only

HI Team,

am getting below error kindly look and give me solution...

[root@usr ~]# passwd -u oracle
Unlocking password for user oracle.
passwd: Error 179 - error creating `/etc/passwd-': Read-only file system.
passwd: Error (password not set?)
[root@usr ~]#

Sounds like you booted from a CD. Are you trying to repair the system disk?

HI Jim,

we didn't repair...what rebooted system..

Try:

mount -o remount, rw X /

in place of X specify the disk label, like

/dev/hda5

Still not reslove the issue..any other solution for this..
