如何处理删除节点后不干净的OCR

icnm

新接手一个2节点RAC版本11.2.0.1，原来是3节点，删除了一个节点，现在这个RAC要做升级，检查发现OCR仍然存有第3个节点gridc（已经删除）的信息，ocrdump文件见附件，请教各位如何处理干净，保证以后升级到11.2.0.2或3的正确性
$cluvfy comp ocr 居然报:
[grid@grida ~]$ cluvfy comp ocr
Verifying OCR integrity
Checking OCR integrity...
Checking the absence of a non-clustered configuration...
All nodes free of non-clustered, local-only configurations

其中GRID的$GI_home设置正确，但cluvfy居然找到oracle用户的$ORACLE_HOME

在11.2 中清理ocr  和votedisk 可以参考以下步骤

Case 1: “root.sh” never ran on this cluster, then as grid user, execute $GRID_HOME/deinstall/deinstall
Case 2: “root.sh” already ran, then follow the step below – please keep in mind that you will need wait till each step finishes successfully before move to next one:
Step 1: As root, run “$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force” on all node, except the last one.
Step 2: As root, run “$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force -lastnode” on last node. This command will zero out OCR and VD disk also.
Step 3: As grid user, run “$GRID_HOME/deinstall/deinstall” on any node.
