由于環(huán)境中需要掛載遠端系統(tǒng)，所以就用NFS來實現(xiàn)，為了在系統(tǒng)啟動的時候或者用戶訪問的時候就進行掛載不用手動參與，于是就用linux的autofs功能來實現(xiàn)：

source OS:

[root@szpa-bak-db2 ~]# more /etc/exports/u02/backupset/140_expback 16.41.169.139(rw,no_root_squash)
[root@szpa-bak-db2 ~]#

target OS:

[oracle@localhost exp_back]$ more /etc/auto.master#
# $Id: auto.master,v 1.4 2005/01/04 14:36:54 raven Exp $
#
# Sample auto.master file
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# For details of the format look at autofs(5).
#
/misc /etc/auto.misc
/net -hosts
/u02/backup/expbk /etc/auto.nfs#
# Include central master map if it can be found using
# nsswitch sources.
#
# Note that if there are entries for /net or /misc (as
# above) in the included master map any keys that are the
# same will not be seen as the first read key seen takes
# precedence.
#
+auto.master

[oracle@localhost exp_back]$ more /etc/auto.nfsexp_back -rw,bg,hard,rsize=32768,wsze=32768 16.41.169.140:/u02/backupset/140_expback[root@localhost exp_back]# /etc/init.d/autofs restart
Stopping automount: [ OK ]
Starting automount: [ OK ]
