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
