asm磁盘创建提示“Marking disk "VOL1" as an ASM disk: [FAILED]”

  今天是2013-11-29，今天安装了一下asm，在创建磁盘的时候出现一个问题如下：

Marking disk "VOL1" as an ASM disk: [FAILED]

产生该问题原因在此总结如下：

1）ASM driver is disable

2）Device "/dev/xxx" is not a partition

3）SELINUX=enforcing

对于第一种情况，我们可以使用/etc/init.d/oracleasm status 查看状态，如果没有启动则采用/etc/init.d/oracleasm start 进行启动asm 驱动

2）对于该问题，需要首先划分分区，因为在官网提出只有如下asm才可支持：

Oracle ASM disks are the storage devices that are provisioned to Oracle ASM disk groups. Examples of Oracle ASM disks include:

A disk or partition from a storage array

An entire disk or the partitions of a disk

Logical volumes

Network-attached files (NFS)

3）对于第三中问题可以采用如下解决方法：

[root@oracle-one ~]# cat /etc/selinux/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 - No SELinux policy is loaded.
SELINUX=enforcing

# SELINUXTYPE= can take one of these two values:

#     targeted - Targeted processes are protected,

#     mls - Multi Level Security protection.

SELINUXTYPE=targeted

[root@oracle-one ~]#

[root@oracle-one ~]# cat /etc/selinux/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 - No SELinux policy is loaded.
SELINUX=permissive

# SELINUXTYPE= can take one of these two values:

#     targeted - Targeted processes are protected,

#     mls - Multi Level Security protection.

SELINUXTYPE=targeted

selinux代表安全增强linux，有三个值enforcing记录日志且阻止程序运行，permissive记录警告日志允许程序运行，disable关闭 selinux策略。建议设置permisssive。

[root@oracle-one ~]#

[root@oracle-one ~]# setenforce 0

[root@oracle-one ~]# getenforce

Permissive

[root@oracle-one ~]#
[root@oracle-one ~]# /etc/init.d/oracleasm createdisk VOL1 /dev/sdb1

Marking disk "VOL1" as an ASM disk: [  OK  ]

[root@oracle-one ~]#

 

另外非常重要的一点就是，我们可以通过查看/var/log/oracleasm日志信息进行快速问题定位。

 

That‘s  all！
