当在normal冗余磁盘组中创建卷，那么卷的每个区同样也会被镜像。可以看到卷文件261有128个区。卷大小为1GB，这意味着每个区大小为8MB或8个AU。卷文件有属于它自己的区大小，不像标准的ASM文件继承来自磁盘组AU大小来初始化区大小。
在逻辑卷设备上创建ASM集群文件系统（ACFS）
[grid@jyrac1 ~]$ /sbin/mkfs -t acfs /dev/asm/acfs_vol1-10
mkfs.acfs: version = 11.2.0.4.0
mkfs.acfs: on-disk version = 39.0
mkfs.acfs: volume = /dev/asm/acfs_vol1-10
mkfs.acfs: volume size = 1073741824
mkfs.acfs: Format complete.
[grid@jyrac1 ~]$ /sbin/mkfs -t acfs /dev/asm/acfs_vol2-10
mkfs.acfs: version = 11.2.0.4.0
mkfs.acfs: on-disk version = 39.0
mkfs.acfs: volume = /dev/asm/acfs_vol2-10
mkfs.acfs: volume size = 1073741824

[root@jyrac1 /]# mkdir /acfs1
[root@jyrac1 /]# mkdir /acfs2
[root@jyrac1 /]# mkdir /acfs3
[root@jyrac1 /]# chown -R grid:oinstall /acfs1
[root@jyrac1 /]# chown -R grid:oinstall /acfs2
[root@jyrac1 /]# chown -R grid:oinstall /acfs3
[root@jyrac1 /]# chmod -R 777 /acfs1
[root@jyrac1 /]# chmod -R 777 /acfs2
[root@jyrac1 /]# chmod -R 777 /acfs3
[root@jyrac1 /]# mount -t acfs /dev/asm/acfs_vol1-10 /acfs1
[root@jyrac1 /]# mount -t acfs /dev/asm/acfs_vol2-10 /acfs2
[root@jyrac1 /]# mount -t acfs /dev/asm/acfs_vol3-10 /acfs3
[root@jyrac1 /]# mount | grep acfs
/dev/asm/acfs_vol1-10 on /acfs1 type acfs (rw)
/dev/asm/acfs_vol2-10 on /acfs2 type acfs (rw)
/dev/asm/acfs_vol3-10 on /acfs3 type acfs (rw)
复制一些文件到新的文件系统中
[grid@jyrac1 +asm]$ cp $ORACLE_BASE/diag/asm/+asm/+ASM1/trace/* /acfs1
[grid@jyrac1 +asm]$ cp $ORACLE_BASE/diag/asm/+asm/+ASM1/trace/* /acfs2
[grid@jyrac1 +asm]$ cp $ORACLE_BASE/diag/asm/+asm/+ASM1/trace/* /acfs3
检查使用空间
[root@jyrac1 /]# df -h /acfs?
Filesystem Size Used Avail Use% Mounted on
/dev/asm/acfs_vol1-10
1.0G 105M 920M 11% /acfs1
/dev/asm/acfs_vol2-10
1.0G 105M 920M 11% /acfs2
/dev/asm/acfs_vol3-10
1.0G 105M 920M 11% /acfs3
现在向ACFS磁盘组添加磁盘组并监控rebalance操作
SQL> alter diskgroup ACFS add disk '/dev/raw/raw7';
Diskgroup altered.
