执行root.sh时，报ORA-15017、ORA-15003错

错误现象 在其中一个node运行root.sh时，出现以下错误： ORA-15018 diskgroup cannot be created ORA-15017 diskgroup OCR_VOTING_DG cannot be mounted ORA-15003 diskgroup OCR_VOTING_DG already mounted in another lock name space

原因 一个节点没跑完，另一个节点就跑了

案例解决方法 删除crs配置信息后重新跑 Oracle Database - Enterprise Edition - Version 11.2.0.1 and later Information in this document applies to any platform.Symptoms Multiple nodes cluster, installing 11gR2 Grid Infrastructure for the first time, root.sh fails on the first node. Solution

1.Deconfig the Grid Infrastructure without removing binaries, refer to Document 942166.1 How to Proceed from Failed 11gR2 Grid Infrastructure (CRS) Installation. For two nodes case:

As root, run $GRID_HOME/crs/install/rootcrs.pl -deconfig -force -verbose on node 1, As root, run $GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force -lastnode on node 2.

Rerun root.sh on the first node first, only proceed with the remaining node(s) after root.sh completes on the first node.
