FYI: I have contacted the author of the change which seems to be related to 
this 
issue if he could have a look. Otherwise, I would be willing to investigate 
further.

Replacing

/etc/fs/nfs/mount
and /usr/lib/autofs/automountd

with binaries from snv_98 avoids this issue for manual mounts and autofs.

Hi,

does anyone know about this issue already?

Observed on snv_101b, was still working on snv_98. Here's a simple test case:

# share something
root at haggis:~# share
-   /tmp/a   sec=sys,ro   ""

# set up a forwarded port
haggis:~$ ssh -L22049:127.0.0.1:2049 localhost

# trying to access with NFSv4 is fine:
root at haggis:~# mount -o ro nfs://127.0.0.1:22049/tmp/a /mnt
root at haggis:~# nfsstat -m
/mnt from nfs://127.0.0.1:22049/tmp/a
  Flags: 
vers=4,proto=tcp,sec=sys,hard,intr,link,symlink,acl,rsize=1048576,wsize=1048576,retrans=5,timeo=600
  Attr cache:   acregmin=3,acregmax=60,acdirmin=30,acdirmax=60

# trying to access with NFSv3 give me a stale file handle (uh?)
root at haggis:~# mount -o ro,vers=3 nfs://127.0.0.1:22049/tmp/a /mnt
nfs mount: mount: /mnt: Stale NFS file handle

Trying to access a remote Solaris 9 box

root at haggis:~# mount -o ro,vers=3 nfs://localhost:12049/export/installserver 
/tmp/b
nfs mount: mount: /tmp/b: Stale NFS file handle

I am very sure that this does work with snv_98, so have I missed anything? Is 
this a new or known issue? If new, could anyone please try to reproduce with a 
tip version?

Thank you,

Nils
