掛載 NFS 硬碟

# mount -t nfs 163.17.50.XXX:/mnt/array1/backup/ /backup/

mount: wrong fs type, bad option, bad superblock on 163.17.50.XXX:/mnt/array1/backup/,

       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.

因為沒安裝 nfs 出現錯誤訊息，安裝就好：

#  yum install nfs-utils
