[Bug 1973101] Re: After upgrade to 22.04 NFS exports for vers 2 and 3 no longer work

[Andreas Hasenack]

Hi,

I believe NFS version 2 is no longer supported. I will check when that
was dropped exactly.

Regarding v3, the UDP transport is no longer available, only TCP. Can
you check if your v3 clients are forcing UDP perhaps, and thus failing?
It would in fact be helpful if you could show the error you are getting
from the clients, and any useful logs they might have.

I'm not sure about the above, as far as I know the upgrade process does
not touch /etc/exports. It will create a new /etc/nfs.conf.d/local.conf
file if the upgrade detected you made changes to /etc/default/nfs-*.
What changes do you think were made to /etc/exports?

Title:
  After upgrade to 22.04 NFS exports for vers 2 and 3 no longer work

Status in nfs-utils package in Ubuntu:
  Incomplete

Bug description:
  I upgraded from 20.04 to 22.04 a server which has NFS clients that are
  version 2 (SunOS 4.1.4), version 3 (Redhat 6.2) and version 4.2 (other
  modern Linux systems).

  After upgrading the version 2 and version 3 clients no longer can
  mount the file systems.

  A check with rpcinfo -p showed version 2 no longer being advertised, I
  checked the conf and found the update had disabled it, I re-enabled
  it.

  Version 3 was still advertised, but the mount still fails, and after
  re-enabling version 2, the mount still fails.

  I am also not at all appreciative of the unauthorized changes that the
  upgrade made to my exports file.
