Well, I might have found a workaround, but it's weird, seems to be
DNS-related.

Something I left out (didn't think it was important) is that the 6.3
server is out on our corporate net, so I used a FQDN:

ls -l 6.3-server.example.com/data

But the new server lives in our lab, so it has an RFC1918 address, and
doesn't have a .com TLD.

ls -l 9.2-server.lab/data

I found that if I use the IP address, OR if I terminate the server name
with a '.', it now works.

ls -l /net/10.15.2.22/data/
total 4
drwxr-xr-x  9 root  wheel  512 Dec 20 17:41 iaf2

$ ls -l /net/9.2-server.lab./data/ 
total 4
drwxr-xr-x  9 root  wheel  512 Dec 20 17:41 iaf2

$ ls -l /net/9.2-server.lab/data/
ls: /net/9.2-server.lab/data/: No such file or directory

$ showmount -e 9.2-server.lab
Exports list on 9.2-server.lab:
/data   Everyone

Sorry for the diversion.

if you changed the export file on the server after you tried to mount  
in on the client,
and will not realise this, if that’s the case, usually rebooting the  
client helps.

Thanks Danny

I did try rebooting the client (and server) multiple times to no avail.



what does amq say?
you can, from another host do: amq -h client-host

btw, I thing that nfs_server must also run on the client …
I have nfs_server_enable=YES



$ 20:10:57 ronald@sjakie [~]
grep nfs_ser /etc//defaults/rc.conf
nfs_server_enable="NO"# This host is an NFS server (or NO).


Is your client a NFS server? If not than there is not need for  
nfs_server_enable YES on the client.

Ronald.

Re: NFS and amd on older FreeBSD

[Rick Macklem]

Do you have exactly the same export options specified in /etc/exports
for the 9.3 server as the 6.3 one?
Beyond that, I can only suggest capturing packets when the automount fails
and looking at them in wireshark to see what is actually happening.

I'm not sure if this is related, but afaik FreeBSD up to 8.x used oldNFS by 
default. Are you using option -o for nfsd on your 9.3 nfs Server to force using 
old NFS?

It is just a guess of mine, I'm usually not working much with nfs.

Holger

One correction.  The new server is FreeBSD 9.2, not 9.3.  Replies below

Yes, that makes sense, but I'm using the same client in both cases.  In
rc.conf on client, I have:

nfs_reserved_port_only="YES"
nfs_client_enable="YES"
amd_enable="YES"


And ps shows the amd process started with these flags:

/usr/sbin/amd -p -a /.amd_mnt -l syslog /host /etc/amd.map /net /etc/amd.map

amd.map is the default

$ cat /etc/amd.map 
# $FreeBSD: src/etc/amd.map,v 1.10.8.1 2009/04/15 03:14:26 kensmith Exp
# $
#
/defaults   type:=host;fs:=${autodir}/${rhost}/host;rhost:=${key}
*   opts:=rw,grpid,resvport,vers=3,proto=tcp,nosuid,nodev

This is the same default amd.map as 9.2.

Another data point: I see the same behavior with a 9.2 client:  I can
automount a share from my 6.3 server, but not from the 9.2 server.

Thanks

If you can mount the share manually, there is almost 
certainly nothing wrong with the server. Based on the
error ("No such file or directory"), I would recommend
checking your amd config on the client.

if you changed the export file on the server after you tried to mount in on the 
client,
and will not realise this, if that’s the case, usually rebooting the client 
helps.

my .5 cents

NFS and amd on older FreeBSD

[Karl Young]

I inherited a lab that has a few hundred hosts running FreeBSD 7.2.
These hosts run test scripts that access files that are stored on
FreeBSD 6.3 host.  The 6.3 host exports a /data directory with NFS


On the 7.2 hosts, I can see the exported directory:

$ showmount -e 6.3-host
Exports list on 6.3-host
/data  Everyone

And access it with amd

$ ls -l /net/6-3.host/data

drwxr-xr-x 5 root  wheel  512 Jun  4  2009 git
drwxr-xr-x  4586 root  wheel83968 Nov  2 04:50 home

I'm trying to retire the 6.3 host and replace it with 9.3 (I know it's
old, but it's the best I can do for now).

I export the /data directory on the 9.3 system, and I can see it on my
7.2 hosts.

$ showmount -e  9.3-host
Exports list on 9.3-host:
/data   Everyone

But I can't automount it:

$ ls -l /net/9.3-host/data
ls: /net/9.3-host/data: No such file or directory

If I manually mount the exported directory, it works:

$ sudo mount -t nfs 9.3-host:/data /mnt/data/
$ mount | grep nfs
9.3-host:/data on /mnt/data (nfs)

$ ls -l /mnt/data
total 4
drwxr-xr-x  9 root  wheel  512 Dec 20 17:41 iaf2

I've spent some time on Google, but haven't found a solution.  I realize
these are very old versions, but I'm not in a position to upgrade them
right now.  My last resort will be to use /etc/fstab to do the NFS
mount, but I'd rather avoid that if I can.

Thanks for any pointers on how to resolve this.
