请教刘大，关于CRS下的几个脚本的作用
请问刘大oracle rac crs install 目录下面有几个脚本不太明白是具体做什么用的，官方文档上说的也比较模糊，能不能详细的解释一下，什么情况下用哪个脚本，谢谢rootdelete.sh 和rootdeletenode有什么区别，rootdeinstall和deinstall的区别
貌似11g没有rootdelete和rootdeletenode这个脚本，多了两个rootcrs.pl和roothas.pl，有什么区别呢
这几个脚本分别在什么情况下运用呢？谢谢刘大 # rootdelete.sbs for CRS
#
# This script is run once per CRS_HOME during clusterware deconfiguration or
# to delete configuration on a node
# NOTE:
# This script is supported for backward compatibility in Oracle 11g Release 2
# In future Oracle releases this script will not available for use.
# You must use 'crsHome/crs/install/rootcrs.pl -delete' option to perform
# same operations this script does
rootdeletenode
#!/bin/sh
# Node deconfiguration script. Must be run from a surviving node of
# the cluster *after* stopping all of the Cluster Ready Services daemons
# on the nodes to be deinstalled/deleted.
# USAGE: rootdeletenode node,node-number[,nodei,nodei-number]
# Note: To get node numbers for the nodes to be deleted,
# run the following command:
# $ORA_CRS_HOME/bin/olsnodes -n 似乎是 rootcrs.pl 包了一层 来控制 配置
#
# rootcrs.pl

# NAME
# rootcrs.pl - root configuration script for Oracle Clusterware home
#
# DESCRIPTION
# rootcrs.pl - root configuration script for Oracle Clusterware home
可以看到rootcrs.pl 是从2008年开发的 请问如果11g rac 其中的一个节点主机上的软件（grid、db）lv损坏，软件也没有备份，这个时候应该怎么办呢？ 部分丢失的话 你可以尝试 从完好的节点拷贝， 如果整个文件系统都丢了的话就比较麻烦
