/ partition is mounted but not present in mount

Hello ,

I 've got a problem with the root partition on my SCO 5.0.5 .

When I check the disk with df or mount , I can 't see the root filesystem .
# mount
/stand on /dev/boot read only on Tue Sep 05 16:13:51 2006
/home on /dev/home read/write on Tue Sep 05 16:14:41 2006

But , if I try to mount the root filesystem manually , I get :
# mount /dev/root /
mount: /dev/root is already mounted, / is busy,
or allowable number of mount points exceeded: Device busy (error 16)

Any idea ?
Thanks
Regards

/ is not mounted via a conventional mount command. It it automaticly mounted by the kernel at boot time. There should be a start up script that initializes the mount table prior to other filesystems. It will probably involve something like:
devnm / | setmnt
So my guess is that you have a problem with your startup scripts.

Thank you for your message .
In fact , I compared with another machine (which works correctly) with the same configuration . The startup scripts are identical .

Best regards

The problem was due to a corrupted /dev/null device .
/dev/null was a regular file instead of a device .
I generated it with mknod command .
I restarted the server and now it works .

Thanks
