Initializing the Oracle ASMLib driver: [FAILED]

Initializing the Oracle ASMLib driver: [FAILED]

[root@node1 init.d]# uname -a

安裝ASMLib包：
oracleasm-2.6.18-53.el5-2.0.4-1.el5.i686.rpm
oracleasmlib-2.0.4-1.el5.i386.rpm
oracleasm-support-2.1.3-1.el5.i386.rpm

[root@node1 init.d]# ./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 without typing an
answer will keep that current value.  Ctrl-C will abort.

Default user to own the driver interface [root]: oracle

搜尋網路報該錯以下2個原因：

1.安裝對應核心的oracleasm包，確定過了，安裝包是正確的。

2.關閉SELINUX:
[root@node1 selinux]# cat config
# 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 - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
SELINUXTYPE=targeted

也是disabled

檢視var/log下的日誌：
cat /var/log/oracleasm

檢視oracleasm模組：

ls /lib/modules
2.6.18-53.el5  2.6.18-53.el5xen

發現模組在/lib/modules/2.6.18-53.el5/kernel/drivers/addon/oracleasm/oracleasm.ko
然後，2.6.18-53.el5xen下面沒有oracleasm.ko模組，恰好linux執行在2.6.18-53.el5xen下。所以報找不到oracleasm模組。

於是網上再次到asmlib網站看了看，發現了包：
oracleasm-2.6.18-53.el5xen-2.0.4-1.el5.i686.rpm

難道這個el5xen包就能將oracleasm module放到2.6.18-53.el5xen下。

搞定，以前一直都是安裝的那3個包，還沒注意到xen這個包。哈哈！
