[Bug 680680] Re: mount picks the wrong version of NFS filesystem

[Christian Mudra]

I solved the problem by updating to nfs-common-1.2.2-1ubuntu1 and nfs-
kernel-server-1.2.2-1ubuntu1 (both taken from maverick), and the related
am-utils problem by updating to am-utils-6.2+rc20110530-1ubuntu1, taken
from oneiric (luckily all the prerequsites for these packages are
fulfilled by lucid/lucid-updates).

Just for the records: A mount in the shell now results in an nfs4-mount, the mount by am-utils uses nfsv3 with a 256k read/write-blocksize if nothing is spezified in the amd maps.
Moving of files larger than 2 GB to the nfs share is now finally possible :-)

Title:
  mount picks the wrong version of NFS filesystem

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

Bug description:
  I have a server running 10.04 and a desktop running 10.10. The server
  has a directory I am trying to mount using NFS. When letting it guess
  the NFS version it chooses incorrectly.

  Here is the command I use to mount my desired directory.
  > sudo /sbin/mount.nfs 192.168.1.20:/public /mnt/server -o rw

  /etc/mtab looks like this and the mount directory doesn't show any files.
  192.168.1.20:/public /mnt/server nfs rw,vers=4,addr=192.168.1.20,clientaddr=192.168.1.147 0 0

  By forcing version 3 on the command line it works.
  > sudo /sbin/mount.nfs 192.168.1.20:/public /mnt/server -o rw,vers=3

  /etc/mtab looks like this and the mount directory correctly shows the files.
  192.168.1.20:/public /mnt/server nfs rw,vers=3,addr=192.168.1.20 0 0
