[Bug 891825] Re: NFS client doesn't mount or mounts slow on startup on 11.10

[enedene]

First of all its NFS3 for sure, if I put nfsvers=4 parameter and try to
mount -a I get:

mount.nfs: mounting ubuntuserver:/media/huge failed, reason given by server:
  No such file or directory
mount.nfs: mounting ubuntuserver:/media/externi-disk failed, reason given by server:
  No such file or directory

It's not firewall.
Mine server is on 192.168.0.1, and client is 192.168.0.2.
Here is an ufw rule:
sudo ufw status:
...

To                         Action      From
--                         ------      ----
Anywhere                   ALLOW       192.168.0.2

Next I did a zenmap port scan, from client to server, here you are:

As you can see everything is open, ports 50000 and 50001 on server are the ones for NFS.
I've also added on server hosts.allow: ALL: 192.168.0.2, and on client ALL: 192.168.0.1

On every other version of ubuntu this worked fine, and I haven't been
changing any configuration on server.

Title:
  NFS client doesn't mount or mounts slow on startup on 11.10

Status in “nfs-utils” package in Ubuntu:
  Invalid

Bug description:
  Here is the problem. I have a ubuntu server 10.04 and installed nfs-server.
  Every client I had till 11.10, would mount the folders at startup. Here is my fstab on Ubuntu 11.10 client:

  ubuntuserver:/media/huge /media/huge nfs rsize=16384,wsize=16384,rw,auto,nolock
  ubuntuserver:/media/externi-disk /media/externi-disk nfs rsize=16384,wsize=16384,rw,auto,nolock

  I have to wait for a minute till these directories get mounted. I have not changed any setup on 10.04 server, the previous 11.04 mounted the disks out of the box.
  The problem is that I have lot of setup files on my server, for example I have a link to pidgin, thunderbird etc. and on startup these programs can't get to their data. Network rises up fast on startup so that shouldn't be a problem.
