核实刚刚创建的ASM磁盘组的实际大小

ASMCMD> lsdg

State    Type    Rebal  Sector  Block       AU  Total_MB  Free_MB  Req_mir_free_MB  Usable_file_MB  Offline_disks  Voting_files  Name

创建 Oracle ADVM 卷

ASMCMD> volcreate -G GOLDENGATE -s 1900m GOLDENGATE

注意这里 -s 选项指定的大小一定不得超过lsdg 显示的实际大小值，否则会报如下错误：

ASMCMD> volcreate -G GOLDENGATE -s 1950m GOLDENGATE

ORA-15032: not all alterations performed

ORA-15041: diskgroup "GOLDENGATE" space exhausted (DBD ERROR: OCIStmtExecute)

确定Oracle ADVM 卷是否创建

ASMCMD> volinfo -G GOLDENGATE GOLDENGATE

Diskgroup Name: GOLDENGATE

         Volume Name: GOLDENGATE

         Volume Device: /dev/asm/goldengate-257

         State: ENABLED

         Size (MB): 1920

         Resize Unit (MB): 32

         Redundancy: UNPROT

         Stripe Columns: 4

         Stripe Width (K): 128

         Usage:

         Mountpath: 

SQL> col volume_device for a30

SQL> col volume_name for a30

SQL> SELECT volume_name, volume_device FROM V$ASM_VOLUME

  2       WHERE volume_name ='GOLDENGATE';

VOLUME_NAME                    VOLUME_DEVICE

------------------------------ ------------------------------

GOLDENGATE                     /dev/asm/goldengate-257

3、创建Oracle ACFS 文件系统

[root@rac1 ~]# /sbin/mkfs -t acfs /dev/asm/goldengate-257

mkfs.acfs: version                   = 11.2.0.3.0

mkfs.acfs: on-disk version           = 39.0

mkfs.acfs: volume                    = /dev/asm/goldengate-257

mkfs.acfs: volume size               = 2013265920

mkfs.acfs: Format complete.

在节点1和2上分别创建 ACFS 文件系统的挂载点

[root@rac1 ~]# su - oracle

[oracle@rac1 ~]$ mkdir -p /home/oracle/ggs

[root@rac2 ~]# su - oracle

[oracle@rac2 ~]$ mkdir -p /home/oracle/ggs

在集群 mount registery 中注册刚刚创建的 ACFS 文件系统，也可以不注册，直接手动挂载。

注册 ACFS 文件系统的好处是在集群每隔30秒检查 mount registery 时会在每个节点自动挂载该文件系统，同时当集群软件或系统重启后也会自动挂载该文件系统。

[root@rac1 ~]# /sbin/acfsutil registry -a /dev/asm/goldengate-257 /home/oracle/ggs

acfsutil registry: mount point /home/oracle/ggs successfully added to Oracle Registry

手动挂载命令如下：

[root@rac1 ~]# /bin/mount -t acfs /dev/asm/goldengate-257 /home/oracle/ggs

执行注册命令后等待30秒，然后在各节点查看ACFS文件系统是否挂载

[root@rac1 ~]# df -h

Filesystem            Size  Used Avail Use% Mounted on

/dev/sda1              30G   20G  7.7G  73% /

/dev/sda3            1003M   39M  914M   5% /tmp

tmpfs                 1.3G  454M  814M  36% /dev/shm

/dev/asm/goldengate-257

                      1.9G   73M  1.9G   4% /home/oracle/ggs

[oracle@rac2 ~]$ df -h

Filesystem            Size  Used Avail Use% Mounted on

/dev/sda1              30G   21G  7.3G  74% /

/dev/sda3            1003M   39M  914M   5% /tmp

tmpfs                 1.3G  450M  818M  36% /dev/shm

/dev/asm/goldengate-257

                      1.9G  137M  1.8G   8% /home/oracle/ggs

4、测试文件系统

[root@rac1 ~]# chown -R oracle:oinstall /home/oracle/ggs

第一节点

[oracle@rac1 ~]$ echo "Oracle ACFS File System" > /home/oracle/ggs/acfs.log

[oracle@rac1 ggs]$ more /home/oracle/ggs/acfs.log

Oracle ACFS File System

第二节点

[oracle@rac2 ~]$ more /home/oracle/ggs/acfs.log

Oracle ACFS File System
