Description Peter Staubach 2008-04-02 14:16:38 UTC
It appears that even when the option, nfsvers=3, is specified on the
client, if the server fails to respond to a MOUNT v3 ping, then the
mount command backs off to NFSv2.

To reproduce:

- Start the mount daemon on the server telling it to respond only to
  MOUNT v1 requests.
- Attempt to mount a file system on a client, specifying vfsvers=3.
- Look to see what version of the NFS protocol was actually used.

A packet capture, from RHEL-4, seemingly shows this backoff.

Comment 3 Bug Zapper 2009-06-09 23:58:29 UTC
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 9 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
