nfs error

mount -t nfs 10.173.55.154:/oradata /oradata

mount: wrong fs type, bad option, bad superblock on 10.173.55.154:/oradata,

       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

[root@raccontroller ~]#  dmesg | tail
