Server B

Let's check what is mounted

         -hosts           /net             autofs Jul 21 08:25 ro,soft,nobrowse,ignore

Switch to my user to check the automount content
Code:
a01s:root# su - spsy
a01s:spsy$ cd /vhe/p02s/home/s/rapports_cme
a01s:spsy$ ls -altr
total 8
drwxrwsr-x   31 spsy     spec           4096 Jun 25 08:20 ../
drwxrwsr-x    2 spsy     spec            256 Jul 20 14:01 ./
a01s:spsy$ exit

The automount is responding but is showing no files or directories. Let's try it manually
Code:
a01s:root# mount p02s:/home/s/rapports_cme /mnt
a01s:root# su - spsy
a01s:spsy$ cd /mnt
a01s:spsy$ ls -altr

It's working this way.

         /dev/hd2         /usr             jfs2   Jul 21 08:25 rw,log=/dev/hd8
         /dev/hd9var      /var             jfs2   Jul 21 08:25 rw,log=/dev/hd8

         /dev/fslv09      /home/sdbc       jfs2   Jul 21 08:25 rw,log=INLINE
         /dev/lv_cme      /www/docs/Rapports-CME jfs2   Jul 21 08:25 rw,log=INLINE
         -hosts           /vhe             autofs Jul 21 08:25 rw,soft,nobrowse,ignore
         -hosts           /net             autofs Jul 21 08:25 ro,soft,nobrowse,ignore
         -hosts           /vhe/p02s/home   autofs Jul 21 09:34 rw,soft,nobrowse,nest,ignore
p02s     /home            /vhe/p02s/home   nfs3   Jul 21 09:34 rw,soft,nest
         -hosts           /vhe/p02s/home/cores autofs Jul 21 09:34 rw,soft,nobrowse,nest,ignore
p02s     /home/s/rapports_cme /mnt             nfs3   Jul 21 09:35

I would expect entries for my /vhe/p02s/home/s/rapports_cme in the mount output but they are obviously not there.

Let's try to create a file
Code:
a01s:spsy$ cd /vhe/p02s/home/s/rapports_cme
a01s:spsy$ echo "test automount path" > test_file.txt
a01s:spsy$ ls -altr

drwxrwsr-x   31 spsy     spec           4096 Jun 25 08:20 ../

drwxrwsr-x    2 spsy     spec            256 Jul 21 09:48 ./

Let's check on /mnt if it's there
Code:
a01s:spsy$ cd /mnt
a01s:spsy$ ls -altr
total 24

Thought luck...

Let's go back on Server A to check what's happening
Code:
p02s:root# cd /home/s/rapports_cme
p02s:root# ls -altr
total 24

drwxrwxr-x   12 spsy     spec           4096 Jul 21 09:47 ./

File is not there either...

Let's try to umount the filesystem and see what lies underneath
Code:
p02s:root# cd /
p02s:root# umount /home/s/rapports_cme
p02s:root# cd /home/s/rapports_cme
p02s:root# ls -altr
total 16
drwxrwsr-x   31 spsy     spec           4096 Jun 25 08:20 ../
-rw-rw-r--    1 spsy     spec             20 Jul 21 09:48 test_file.txt
drwxrwsr-x    2 spsy     spec            256 Jul 21 09:48 ./
p02s:root# cat test_file.txt
test automount path

Here's the file

What I can understand, is the /home/s/rapports_cme filesystem is not mounted correctly by the automount on server B. Is it because server A is already exporting it's parent directory ? I guess. Is it a bug with automount or is it suppose to act like that ?
