ORACLE Initializing the Oracle ASMLib driver: [FAILED]

在配置asm服务时，遇到以下错误：

[root@db1 tmp]# service oracleasm configure

Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASM library

driver.  The following questions will determine whether the driver is

loaded on boot and what permissions it will have.  The current values

will be shown in brackets ('[]').  Hitting <ENTER> without typing an

answer will keep that current value.  Ctrl-C will abort.

Default user to own the driver interface []: grid

Default group to own the driver interface []: asmadmin

Initializing the Oracle ASMLib driver:                     [FAILED]

Cause：

首先查看日志/var/log/oracleasm

[root@db1 tmp]# more /var/log/oracleasm

Disk "ASM_DATA1" does not exist or is not instantiated

Loading module "oracleasm": failed

Unable to load module "oracleasm

发现出错是由于无法加载oracleasm 模块

Solution：

查看该模块是否存在：

[root@db1 tmp]# find / -name "oracleasm.ko"

/lib/modules/2.6.18-164.el5/kernel/drivers/addon/oracleasm/oracleasm.ko

若存在，手动安装该模块

[root@db1 lib]# which insmod

/sbin/insmod

[root@db1 lib]# insmod /lib/modules/2.6.18-164.el5/kernel/drivers/addon/oracleasm/oracleasm.ko

再次尝试，这次就成功了。

[root@db1 lib]# service oracleasm configure

但是这种方法治标不治本

想要彻底更正这个错误，需要对应系统内核版本正确的安装asm的包。

[root@db1 grid]# uname -r

[root@db1 tmp]# ll oracleasm*
