Hi
I am sort of new to Apollo's. So please excuse me if this is a dumb question.
Problem description:
--------------------
We have a DN10000 running SR10.1 and a 780 MB disk. We mount filesystems from
our Sun servers onto the DN10000.
We mount all the filesystems as 'hard' onto the DN10000. As I understand it,
by using a 'hard' mount that filesystem is mounted forever. Which is fine
with us.
Now somehow we managed to erase the /etc/mtab file during all this. And now
whenever we try to mount another filesystem from a Sun onto this DN10000
it comes back with:
WARNING: MOUNT TABLE CONTAINS NULLS AFTER MODIFICATION
* Is the file /etc/mtab that important?
I have been administering Suns for some time now and /etc/mtab or
(mount table) isn't critical for the operation of NFS.
* If it is important how do I recreate it?
* If it is not important what else am I doing.
My /etc/fstab entry for that filesystem looks like this (other entries also are
similar):
grumpy:/osi1 /osi1 nfs rw,hard 0 0 0
Any ideas? Suggestions?
Thanks.

About a problem getting NFS going on a DN10000.
I had exactly this problem when I installed NFS. It turned out
to be that NFS was very fussy about where mtab AND mnttab were,
and that mnttab was the same as mtab. Here is what our working
setup looks like:
% cd /etc
% ls -l m*tab
lrwxrwxrwx 1 none 21 Jan 4 16:21 mnttab@ -> `node_data/etc/mnttab
lrwxrwxrwx 1 none 21 Jan 4 16:21 mtab@ -> `node_data/etc/mnttab
% cd \`node_data/etc
% cat mnttab
/dev/wn0a / 4.3 rw 631485356 0 0
foo:/bar /baz nfs rw,bg 631485621 0 0
...
Good luck!
