Re: Odd behavior from amd
The amq -u does not remove the symlinks.
We are using nfs maps with symlinks (like this):
juser host!=homehost;rhost:=homehost;rfs:=/wd1e/export/home \
host==homehost;fs:=/wd1e/export/home;type:=link
As I understand it, amd consists of two different logical parts:
1) A server that hooks file system access, looks up the mountpoint,
and mounts it. (in /amd/...)
2) A userland NFS server that serves out a file system full of
symlinks to the mountpoints managed by the above process (in /home).
It seems that part 1 is working, such that if I move a home
directory, and then go crawling around in
/amd/homehost/wd1e/export/home/..., or ask amq, the correct
information will be picked up as expected, and the new filesystem
will be mounted. The problem is that part 2 never seems to get the
message. The galling thing is that it is _so_ close, the automounter
mounts the new file system just fine, so it unmounts
/amd/oldhost/wd1e/export/home/juser and correctly mounts the new tree
at /amd/homehost/wd1e/export/home/juser, but the symlink in /home
still (until amd is restarted) points to
/amd/oldhost/wd1e/export/home/juser which of course no longer exists...
I hope that clears things up. That being said, it is only minimally
disruptive to:
sudo /etc/rc.d/amd stop
sudo /etc/rc.d/amd start
but it just doesn't feel right to have to do that.

What kind of maps are you using? Did you verify that after amq -u the
symlink was gone?
