在node1节点上可以执行完root.sh脚本，可是在node2上执行的时候居然是：

[root@node2 ~]# /opt/ora10g/product/10.2.0/crs_1/root.sh
WARNING: directory '/opt/ora10g/product/10.2.0' is not owned by root
WARNING: directory '/opt/ora10g/product' is not owned by root
WARNING: directory '/opt/ora10g' is not owned by root
Checking to see if Oracle CRS stack is already configured
Oracle CRS stack is already configured and will be running under init(1M)

解决：

mv /etc/oracle/scls_scr/node2/oracle/cssfatal /etc/oracle/scls_scr/node2/oracle/cssfatal.bak

重新执行OK
