2018-03-14 08:46:20: ROOTCRS_STACK checkpoint has failed 

参考文档：Oracle Restart: 12.1 grid installation root.sh fails while starting ohasd ( Doc ID 1997268.1 ) 

解决方法：

================================================================ 
Workaround: 

Rename the directory to root.bak under .../scls_scr/{nodenanme} and re-run root.sh 
or 

- clean up all directories under .../scls_scr 
- clean all directories under /var/tmp/.oracle 
- deconfig ohasd as in below example and re-run root.sh 

/<GI Home>/crs/install/roothas.pl -deconfig -force 
./root.sh
