If u face any error related to nfs mount like

[root@rhel6-client1 ~]# mount -t nfs 172.16.28.130:/nfsshare /mnt/clientmountpoint/
mount: wrong fs type, bad option, bad superblock on 172.16.28.130:/nfsshare,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog – try

dmesg | tail  or so
