boot failure - coreadm.conf read only file ???


I've got a Sun Netra X1 server running Solaris 9,
When rebooting I got this strange message:

failed to open /etc/coreadm.conf: Read-only file system
INIT: Cannot create /var/adm/utmpx
INIT: failed write of utmpx entry:"  "
INIT: failed write of utmpx entry:"  "

Type control-d to proceed with normal startup,
Type control-d to proceed with normal startup,

I login in Single-User Mode, and did this steps:
# mount -o rw,remount /

Control-d - to bring up the system multi-user.

#fsck -y /

Reboot the system, but still see my error message.

What do I need to get off this failure,

I ve not modified the vfstab file, and its clean I've checked it more then twice! :'(

please helpppppp me!

Assuming you have more than 1 partition, boot into single user mode, do the mount as above then fsck each of the filesystems /var, /usr, /opt etc and mount them

Have tried, but did NOT helped! :(

anyhow, thanks for your help.

When system was trying to open coreadm.conf, it is needed a tmp space to open the file so it will need /tmp partition to be rw.
fsck /tmp partition, if it not mounted than mount it.
and then try to remount /tmp partition to r/w.

if these does not work post us these output when system is at single user mode.

The only time I've ever had the
" INIT: Cannot create /var/adm/utmpx"
 message is when my /var partition wouldn't mount.

btw: How many disks do you have and are they mirrored?
