System table corrupt

I have a N-4000 server with several Oracle instances running. The server is up at this time. However when I do bdf it comes back empty. Nothing is mounted. On executing the mount command I got error "System table may be corrupt". Would only a reboot help this case or could I resolve it without a reboot ? Would anyone know what are the causes of the system table getting corrupted ?

Thank you.

Re: System table corrupt

Hi Atul:

You're /etc/mnttab is corrupt (reason unknown).

Do this:

# mv /etc/mnttab /etc/mnttab.old
# mount -a

This should recreate a valid /etc/mnttab and 'bdf' should again be working.

Re: System table corrupt

You may be able to fix this.

Try this:
mv /etc/mnttab /etc/mnttab.safe
mountall

This should recreate the mnttab.

If it ain't broke, I can fix that.

Re: System table corrupt

Hi James,
Thank you for the quick response. However the system does not have mnttab.old file. My mnttab file is 0 bytes. Is there any other way to recreate the mnttab file ?

Thanks

Re: System table corrupt

Sorry, if /usr is not mounted. You will need to do an /sbin/mountall.
