今天突然想起来RAC测试环境的ASM磁盘组空间不够，每次做恢复测试的时候总会报错说空间不够，所以今天打算把openfiler的空间扩展一下，然后想ASM磁盘组中添加磁盘。

1 连接到RAC的测试环境中 执行crs_stop -all 将所有应用停止

2 将openfiler虚拟机添加128G的硬盘，重启openfiler

3 进入 https://openfiler_IP:446/ 配置新添加的磁盘 建立ISCSI磁盘

4 重启两个RAC节点，目的是为了让两个机器能重新扫描到新建立的ISCSI磁盘

5 fdisk 磁盘

6 创建ASM磁盘

[root@mestest1 ~]# /etc/init.d/oracleasm createdisk VOL8 /dev/sdo1

Marking disk "VOL8" as an ASM disk: [  OK  ]

[root@mestest1 ~]# /etc/init.d/oracleasm createdisk VOL9 /dev/sdp1

Marking disk "VOL9" as an ASM disk: [  OK  ]

[root@mestest1 ~]# /etc/init.d/oracleasm createdisk VOL10 /dev/sdq1

Marking disk "VOL10" as an ASM disk: [  OK  ]

[root@mestest1 ~]# /etc/init.d/oracleasm listdisks

VOL1

VOL10

VOL2

VOL3

VOL4

VOL5

VOL6

VOL7

VOL8

VOL9

7 到另外一个节点上执行 /etc/init.d/oracleasm scandisks 扫描磁盘 

/etc/init.d/oracleasm listdisks 出现如上相同结果为正确 

8 想ASM磁盘组中添加磁盘

Diskgroup altered.

SQL> alter diskgroup DATA add disk 'ORCL:VOL9' rebalance power 1;
