Expected results:


Additional info:
mount  -o nfsvers=3  127.0.0.1:/tmp  /media/   # this works fine
mount.nfs  -o nfsvers=3  127.0.0.1:/tmp  /media/   #can not work

RHEL5.9 has same problem.

Comment 4 RHEL Program Management 2013-10-14 02:19:45 UTC
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 6 Steve Dickson 2014-05-23 10:21:38 UTC
mount.nfs is not the supported way to do NFS mount. 

mount -o vers=3 works

In RHEL-7, it works fine;
I think we should fix(or improve) it.

mount.nfs server:/export -o vers=3 also works... 

I would rather spend our resources working on other things...

Comment 10 JianHong Yin 2014-05-26 01:18:47 UTC
Ok. But I still want to express different points of view:

GNU tools popular, one of the reasons is that there is no limited position of parameters and options;

And, that is easy to fix. So I try again to reopen..
  for our software with better user experience.

Comment 11 Steve Whitehouse 2015-12-11 18:30:25 UTC
I agree with Steve D, no customer has run into this yet. We expect people to use the mount wrapper rather than mount.nfs directly. I don't think we need to fix this, and we should definitely focus on the more important bugs at this stage. It is apparently fixed in RHEL7 anyway (comment #2) and I don't think we need to back port it.
