automount sun filesys on sgi

[Andrew Torda]

I have been happily using the automounter from sun to sun, but
can't get an iris to automount a disk from a sun (ordinary nfs
mounts do work).

Now, I have an entry in auto.direct like
/disk1           -rw        sun1:/disk1

Now, the automounter makes a link from /disk1 to /tmp_mnt/disk1
no problems. It says
lrwxrwxrwx   1 root     sys         20 Apr 14 18:31 disk1@ -> /tmp_mnt/disk1

If I try to cd /disk1, the sgi says 
     /disk1: Not a directory
and looking in /tmp_mnt, there is nothing there.
Obviously cd'ing into /tmp_mnt/disk1 also fails.

Now, if I
  ls -l /
I can see from the trace option that the automounter makes an nfs
request and, remarkably, disk1 is mounted.
Note, that I have not moved into the mount point itself.
Now, I try to
  cd /disk1
and it again says
  /disk1: Not a directory
despite the fact that the link is in place as in the extract from ls
above.

When the mount happens, it is working. I can go into /tmp_mnt/disk1
and look around, so it is not a problem with mountd on the sun side.

To finish this, I have now often tried to killall -15 automount.
This leads to further disasters. Now, with the automounter turned off,
any attempt to access /disk1 seems to hang.
Furthermore, there is nothing in /usr/adm/SYSLOG to suggest why it is
hanging.

All this happens with Irix 3.3.2 and SunOs 4.1
As a final experiment, I can make the sgi an exporter and successfully
automount its file system to a sun client. Just won't work the
other way round.

Thanks in advance for any suggestions.
