root.sh执行失败，Relinking rac_on failed

admin

os=suse12sp3,db=12.2.0.1安装grid到执行root.sh的时候
1节点执行成功，crsctl status res -t 显示集群正常。
2节点执行时报错：
Relinking oracle with rac_on option
Relinking rac_on failed

尝试手动操作
$ export ORACLE_HOME=$GRID_HOME
$ cd $ORACLE_HOME/rdbms/lib
$ make -f ins_rdbms.mk rac_on ioracle
报错：
libpthread.so.0: undefined reference to `__tdelete@GLIBC_PRIVATE'

CAUSE
This is caused by $GI_HOME/lib/stubs/libpthread.so mismatched with $GI_HOME/lib/stubs/libpthread.so.0

SOLUTION
Perform below steps to make soft link as grid home user:

$ mv $GI_HOME/lib/stubs/libpthread.so $GI_HOME/lib/stubs/libpthread.so_bak
$ ln -s $GI_HOME/lib/stubs/libpthread.so.0 $GI_HOME/lib/stubs/libpthread.so

再次尝试执行rootsh，执行成功。
