see asmca logs at /opt/ogrid/cfgtoollogs/asmca for details
Did not succssfully configure and start ASM at /opt/grid/products/11.2.0/crs/install/crsconfig_lib.pm line 6912.
/opt/grid/products/11.2.0/perl/bin/perl -I/opt/grid/products/11.2.0/perl/lib -I/opt/grid/products/11.2.0/crs/install /opt/grid/products/11.2.0/crs/install/rootcrs.pl execution failed

方案1：修改voting盘权限

chown oracle:oinstall /dev/qdata/voting

find / -name roothas.pl

/opt/grid/products/11.2.0/crs/install/roothas.pl -deconfig -force -verbose

/opt/grid/products/11.2.0/root.sh

不好使。。。

方案2：查看报错日志

ORA-48141: error creating directory during ADR initialization [/opt/ogrid/diag/asm]
ORA-48189: OS command to create directory failed

报这个错前有这个ora错误，然后检查发现diag目录权限是root

ls -lh /opt/ogrid
drwxrwxr-x 3 root root     4.0K Jan  6 16:21 diag

修改权限
chown -R grid:oinstall /opt/ogrid/diag/asm

重新执行root.sh

节点2执行root.sh报错

CRS-5804: Communication error with agent process
CRS-4000: Command Start failed, or completed with errors. CSS startup failed with return code 1 The exlusive mode cluster start failed, see Grid Infrastructure alert log for more information Initial cluster
