基於CentOS與VmwareStation10搭建Oracle11G RAC 64集群環境：4.安裝Oracle RAC FAQ-4.2.Oracleasm Createdisk ASM磁盤失敗:Instantiating disk: failed

1.錯誤信息：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.解決辦法：

1.首先檢查Oracle ASMlib、oracleasm與 Linux內核版本是否一致，通常版本不一致，會導致此問題。

[root@linuxrac2 etc]# uname -r

2.6.18-164.el5

若不一致，請在Oracle ASMlib下載地址下載：

2.可能selinux 阻止訪問disk header

[root@linuxrac1 etc]# cd selinux

[root@linuxrac1 selinux]# ll

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

#     enforcing - SELinux security policy is enforced.

#     permissive - SELinux prints warnings instead of enforcing.

#     disabled - No SELinux policy is loaded.

#SELINUX=enforcing

SELINUX=disabled

# SELINUXTYPE= can take one of these two values:
