NFS Mounts not visible

I have a particular server. It mounts three NFS shares. They mount
successfully upon reboot and stay mounted and accessible.

All good, EXCEPT the mounts are not visible when I type "mount". That
causes my self monitoring scripts to complain and I do not like it.

So, why would a directory be mounted from fstab, but not visible in
mtab?

I am using Ubuntu Gutsy.

Do they show up in cat /proc/mounts ?

Yes, they do. I guess I can use that instead for self monitoring.

Thanks.

This happened to me once when the mounts are done before / has been
remounted read + write.

What strange distribution do you use that mounts nfs before / is mounted
rw ?

Nico

Note : this also could indicate that your / has been remounted RO after
an error. Check dmesg.

I am not sure if your diagnosis is correct. Could be something
else.

That server runs ubuntu gutsy.

Like the Note: that Nicolas wrote, that you snipped, that it could be an
error with the / filesystem, so it's still mounted read-only? Did you
check that / is mounted rw?

Yes, it is rw.

I have seen this problem on a couple of mainstream distributions. You
basically need to run mount again to update the mtab, which was not
updated properly during boot time, because the root filesystem is
switched to read only for part of the boot process. To update mtab run:

mount -f

Mark.

Thanks. I do not care about this now, any more, I look into
/proc/mounts.
