UNIX for Advanced & Expert Users

How about

Code:

mkdir /var
mkdir /var/tmp

to create a temp dir for the moment. Sounds like "/var" is not mounted.

Thank's Porter,

I'm very confused , the file system just can read only. can't create some file.
How about repair from cd master?
till now I'm just using single mode, can't multi user ?
any suggestion

You still have not told us what operating system this is.

Sounds like your root file system is mounted read only.

You need to remount the root file system read/write, but need more detail to advise you how to do this.

Please do the following and post the results..

uname -a
mount
df -k

Actually, the OS is mentioned above...

Thanks, I missed that.

man mount

and

man mount_ufs

should be

mount -F ufs -o remount /dev/dsk/c0d0s0 /

default should be read/write.

I am guessing at the device name. Do "df /" to see what it currently is.

Great Porter,

That's right , I'm umounting that device in vfstab file , I think this stupid . I just want using that for mount CDROM.
I have tried that when not finished installing SUN OS, mount cdroom using

Code:

#mount -F hsfs /dev/dsk/c0d0s0 /cdrom

and that work, so I try to finish OS Installer by add package. But my OS not stable and much file broken. And try again by new CD (Download from sun website), this work.
But when I want using CDROM that can't mount automatically, and try mount manual.so I disbale /dev/dsk/c0d0s0..
that cause this trouble

I try your code ,

Code:

#mount -F ufs -o remount /dev/dsk/c0d0s0  /
#mkdir /var/tmp
#vi /etc/vfstab

enable /dev/dsk/c0d0s0 mounting and now I can using multi user again

Thank you Porter,

regards,

heru
