RAC之安装DB SOFT节点间时间一致导致tar错误

这个错误是第1次遇到，在node1上安装soft的过程当中，在进行copy file to remote node2的时候，查看了日志如下：
INFO: List of files to be excluded from:install/excludeFileList.txt
INFO: Exclude file list /tmp/OraInstall2011-11-26_02-13-20PM/installExcludeFile.lst does not exist or is empty. The file is ignored.
WARNING: Error while copying directory /opt/app/product/10.2.0/db_1 with exclude file list 'null' to nodes 'r2'. [PRKC-1002 : All the submitted commands did not execute successfully]
----------------------------------------------------------------------------------
r2:
/bin/tar: ./assistants/dbca???????????? 2011-11-26 14:19:29 ???????????? 10 ?????????
/bin/tar: ./bin/dbv???????????? 2011-11-26 14:19:20 ???????????? 1 ?????????
.。。。。

类似的环境搭建过多次了，也没遇到过，google了下，有网友说是node1的时间必须比node2的慢才可以，而且说明产生的问题也是在复制和tar过程步骤，将信将疑修改了node1的时间比node2慢了将近10分钟，然后先把刚才中途失败的先delete掉，重新运行./runInstaller，擦，果然通过了，最后将node1时间改成与node2一致，以便继续dbca建库。
