[SunHELP] root partition read only fs

[Asif Iqbal]

Hi All

I am getting this message on one of my sparc sol 8 E 250R

mount: /dev/dsk/c0t8d0s0 is not this fstype.
failed to open /etc/coreadm.conf
syseventd: Unable to open daemon lock file '/etc/sysevent/syseventd_lock': 'Read-only file system'The system is coming up.
Please wait.
/sbin/mountall: /tmp/sh740: cannot create
rm: Unable to remove directory /tmp: Read-only file system
mkdir: Failed to make directory "/tmp"; Read-only file system
chown: /tmp: Read-only file system
ps: open("/tmp/ps.OoaGla") for write failed, Read-only file system
ps: Please notify your System Administrator


This is how my /etc/vfstab looks like

-
swap    -       /tmp    tmpfs   -       yes     -


This is how the format reports it

Any idea why my root filesystem is mounting as read-only

I can mount the root file sytem manually after the system comes back up on /a as
rw

mount /dev/dsk/c0t8d0s0 /a and then can write to it fine. Not sure why it is not
automatically mount as rw

Any help/suggestion would be greatly appreciated

Thanks
