Redhat 下ASM 11.2.0.1 oracleasm deletedisk - Clearing disk header failed 的解决方法

在虚拟机上搭建Oracle 11gR2 的RAC。 安装Clusterware的时候出了一点错误。 所以强行把Clusterware 给删除了。 清除了相关的目录和文件。 因为11gr2 的OCR是存放在ASM上的，所以需要清除这部分信息。

 

 

[root@rac2 ~]# oracleasm listdisks

CRS

[root@rac2 ~]# oracleasm deletedisk CRS

Clearing disk header: failed

[root@rac2 ~]# oracleasm scandisks

可是删除报Clearing disk header: failed错误。 尝试把另一个节点的ASM 停止掉删除，还是不行。

 

看了一下oracleasm的log：

[root@rac1 mapper]# tail -20 /var/log/oracleasm

google了一下。  在Oracle 论坛上找到了解决方法：

 

 

Same problem with 11.2.0.1 on x86-64 RH Linux 5.4.
Had to :
1. shutdown CRS on all nodes of the cluster (# ./crsctl stop crs)
2. disable CRS from starting on reboot (# ./crsctl disable crs)
3. Reboot all the servers (# shutdown -r now)
4. After reboot, stop ASMLIB (# service oracleasm stop)
5. Remove the disk using physical name rather than logical name (service oracleasm deletedisk /dev/mapper/mpath01p1)
6. Restart ASMLIB (# service oracleasm start)
7. Enable CRS on re-boot (# ./crsctl disable crs)

 

 

因为我之前的Cluster已经删除，所以直接停ASM server。 删除就可以了。

[root@rac1 mapper]# service oracleasm stop

Dropping Oracle ASMLib disks: [  OK  ]

Shutting down the Oracle ASMLib driver: [  OK  ]

[root@rac1 mapper]# ls

[root@rac1 mapper]# service oracleasm deletedisk /dev/mapper/crsp1

Removing ASM disk "/dev/mapper/crsp1": [  OK  ]

[root@rac1 mapper]# service oracleasm start

Initializing the Oracle ASMLib driver: [  OK  ]

Scanning the system for Oracle ASMLib disks: [  OK  ]

[root@rac1 mapper]# oracleasm listdisks

搞定。  到另一个节点查看：

 

[root@rac2 ~]# oracleasm listdisks

CRS

DATA

FRA

[root@rac2 ~]# oracleasm scandisks

Reloading disk partitions: done

Cleaning any stale ASM disks...

Cleaning disk "CRS"

也同步了。 看来ASM 11在Linux 5.4 上还是有点问题。
