安装完ASM相应组件后，执行/etc/Init.d/oracleasm enable后显示失败。查看日志

原来是找不到ASM组件oracleasm.ko
在文件系统中查找
- [root@localhost log]# find / -name oracleasm.ko
- /lib/modules/2.6.18-53.1.21.el5/kernel/drivers/addon/oracleasm/oracleasm.ko
手工安装ASM组件
- [root@localhost log]# /sbin/insmod /lib/modules/2.6.18-53.1.21.el5/kernel/drivers/addon/oracleasm/oracleasm.ko
/etc/init.d/oracleasm enable执行成功。
