在跑脚本时 ：/u01/app/11.2.0/grid/root.sh
出现如下错误 ：
CRS-4046: Invalid Oracle Clusterware configuration.
CRS-4000: Command Create failed, or completed with errors.

/u01/app/11.2.0/grid/perl/bin/perl -I/u01/app/11.2.0/grid/perl/lib -I/u01/app/11.2.0/grid/crs/install /u01/app/11.2.0/grid/crs/install/rootcrs.pl execution failed
解决方法：
# <grid-home>/crs/install/rootcrs.pl -deconfig -force -verbose
/u01/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -force -verbose
出现如下：

Failure in execution (rc=-1, 256, No such file or directory) for command /etc/init.d/ohasd deinstall
Successfully deconfigured Oracle clusterware stack on this node
# ps -ef| grep <grid-home>
i.e.: # ps -ef| grep "/ocw/grid"
If there's still processes, kill them with "kill -9" command
Once the above reboot or stop is done, as root, execute root.sh from GRID_HOME:
# <grid-home>/root.sh
# ps -ef| grep <grid-home>
如果没有出现如下：i.e.: # ps -ef| grep "/ocw/grid"
则直接
/u01/app/11.2.0/grid/root.sh
