基于CentOS与VmwareStation10搭建Oracle11G RAC 64集群环境：4.安装Oracle RAC FAQ-4.2.Oracleasm Createdisk ASM磁盘失败:Instantiating disk: failed

1.错误信息：Instantiating disk: failed

[root@linuxrac1 /]# /usr/sbin/oracleasm createdisk OCR_VOTE /dev/sdb1

/etc/init.d/oracleasm createdisk OCR_VOTE /dev/sdb1

Writing disk header: done

Instantiating disk: failed

Clearing disk header: done

2.解决办法：

1.首先检查Oracle ASMlib、oracleasm与 Linux内核版本是否一致，通常版本不一致，会导致此问题。

[root@linuxrac2 etc]# uname -r

2.6.18-164.el5

若不一致，请在Oracle ASMlib下载地址下载：

http://www.oracle.com/technetwork/server-storage/linux/downloads/rhel5-084877.html

2.可能selinux 阻止访问disk header

[root@linuxrac1 etc]# cd selinux

[root@linuxrac1 selinux]# ll
