11gr2安裝Grid 時 node2 root.sh失敗Start of resource “ora.asm -init” failed

在安裝GI，第一個節點的root.sh一般不易出錯，但是第二個節點就遇到了下面的錯誤
Start of resource “ora.asm -init” failed
Failed to start ASM
Failed to start Oracle Clusterware stack

檢查錯誤日誌
grid@znode2 crsconfig]$ pwd
/u01/app/11.2.0/grid/cfgtoollogs/crsconfig
[grid@znode2 crsconfig]$ vi + rootcrs_znode2.log

有多種原因可能出現這個問題
1， 是public,private網路卡配置不正確
2，是firewall 未關閉
3，hostname 出現在/etc/hosts的127.0.0.1行

我檢查/etc/hosts
127.0.0.1 znode1 localhost.localdomain localhost
然後把所有節點的127.0.0.1那行改成了
127.0.0.1 localhost.localdomain localhost

關掉OUI，deinstall,重灌安裝順利透過

不關oui,只在失敗的節點
/app/product/grid/11.2.0/crs/install/roothas.pl -delete -force -verbose
重新執行root.sh應該也是可以的。
/app/product/grid/11.2.0/root.sh
