Description of problem: Quoting from 'man mount.nfs': "mount.nfs is used to mount NFS file systems versions 3 or 2" But, mount.nfs nfsserver.example.com:/nfsshare /abc -v gives the following output mount.nfs nfsserver.example.com:/nfsshare /abc -v mount.nfs: timeout set for Wed Aug 3 12:43:57 2016 mount.nfs: trying text-based options 'vers=4,addr=10.7.241.211,clientaddr=10.27.119.29' mount.nfs: mount(2): Permission denied mount.nfs: access denied by server while mounting nfsserver.example.com:/nfsshare Version-Release number of selected component (if applicable): nfs-utils-1.3.0-0.21.el7_2.1.x86_64 How reproducible: Steps to Reproduce: 1. On Red Hat Enterprise Linux Server release 7.2 (Maipo), install nfs-utils-1.3.0-0.21.el7_2.1.x86_64 and tag it as your NFS server. 2. Configure a nfs share with any export version cat /etc/exports.d/myshare.exports /myshare 10.65.202.216/24(rw) 3. On Red Hat Enterprise Linux Server release 7.2 (Maipo), install nfs-utils-1.3.0-0.21.el7_2.1.x86_64 and tag it as your NFS client. 4. Execute the mount.nfs command in verbose mode on the NFS client to mount the NFS share. 5. The mount.nfs command uses nfs version 4 to mount the nfs share, instead of using version 2 or 3 as specified in the manual page of mount.nfs Actual results: mount.nfs 10.65.202.237:/myshare /mnt/nfsexport/ -v mount.nfs: timeout set for Wed Aug 3 18:22:29 2016 mount.nfs: trying text-based options 'vers=4,addr=10.65.202.237,clientaddr=10.65.202.216' 10.65.202.237:/myshare on /mnt/nfsexport type nfs Expected results: mount.nfs 10.65.202.237:/myshare /mnt/nfsexport/ -v mount.nfs: timeout set for Wed Aug 3 18:22:29 2016 mount.nfs: trying text-based options 'vers=3,addr=10.65.202.237,clientaddr=10.65.202.216' 10.65.202.237:/myshare on /mnt/nfsexport type nfs Additional info: If the NFS server is not supporting the version 4 but only version 3; then the mount.nfs gives following error: mount.nfs: timeout set for Wed Aug 3 13:00:28 2016 mount.nfs: trying text-based options 'vers=4,addr=10.65.202.237,clientaddr=10.65.202.216' mount.nfs: mount(2): Permission denied mount.nfs: access denied by server while mounting 10.65.202.237:/myshare
(In reply to Ameya Sathe from comment #0) > Description of problem: > Quoting from 'man mount.nfs': > "mount.nfs is used to mount NFS file systems versions 3 or 2" > I don't see the problem here.... because the man page also says "mount.nfs4 is used for mounting NFSv4 file system" which is the case.

Acked-By: J. Bruce Fields <bfields@fieldses.org> Signed-off-by: Steve Dickson <steved@redhat.com> And then the mount.nfs(8) will look like: "Under Linux 2.6.32 and later kernel versions, mount.nfs can mount all NFS file system versions. Under earlier Linux kernel versions, mount.nfs4 must be used for mounting NFSv4 file systems while mount.nfs must be used for NFSv3 and v2."
Have checked the man page is updated as expected. Move this bug on to VERIFIED.

This subcommand, however, can also be used as a stand‐ alone command with limited functionality. remotetarget is a server share usually in the form of servername:/path/to/share. dir is the directory on which the file system is to be mounted. Under Linux 2.6.32 and later kernel versions, mount.nfs can mount all NFS file system versions. Under earlier Linux kernel versions, mount.nfs4 must be used for mounting NFSv4 file systems while mount.nfs must be used for NFSv3 and v2. [snip...]
