**Oracle 11g ASM之--ACFS创建案例**

**系统环境：**

**操作系统：RedHat EL5（32）**

**Oracle：   Oracle 11g （11.2.0.1.0）**

**Grid Infrastructure： 11.2.0.1.0**

**1、查看ASM DISKGROUP兼容性参数版本**

SQL> select name,STATE ,ALLOCATION\_UNIT\_SIZE ,BLOCK\_SIZE,SECTOR\_SIZE,COMPATIBILITY from v$asm\_diskgroup;  
  
NAME                           STATE       ALLOCATION\_UNIT\_SIZE BLOCK\_SIZE SECTOR\_SIZE COMPATIBILITY  
\------------------------------ ----------- -------------------- ---------- ----------- ------------------------------------------------------------  
DATA                           MOUNTED                  1048576       4096         512**11.2.0.0.0**  
DG1                            MOUNTED                  1048576       4096         512**11.2.0.0.0**  
RCY                            MOUNTED                  1048576       4096         512**11.2.0.0.0**

**2、创建动态卷  
SQL>  ALTER DISKGROUP dg1 ADD VOLUME ACFSARCVOL SIZE 5g;  
 ALTER DISKGROUP dg1 ADD VOLUME ACFSARCVOL SIZE 5g  
\*  
ERROR at line 1:  
ORA-15032: not all alterations performed  
ORA-15477: cannot communicate with the volume driver**

**通过ASMCA无法创建动态卷和ACFS:**

**3、启动ACFS服务**  
\[grid@ocm1 ~\]$ su -  
Password:   
**\[root@ocm1 ~\]\# /u01/11.2.0/grid/bin/acfsroot install**  
ACFS-9300: ADVM/ACFS distribution files found.  
ACFS-9312: Existing ADVM/ACFS installation detected.  
ACFS-9314: Removing previous ADVM/ACFS installation.  
ACFS-9315: Previous ADVM/ACFS components successfully removed.  
ACFS-9307: Installing requested ADVM/ACFS software.  
ACFS-9308: Loading installed ADVM/ACFS drivers.  
ACFS-9321: Creating udev for ADVM/ACFS.  
ACFS-9323: Creating module dependencies - this may take some time.  
ACFS-9327: Verifying ADVM/ACFS devices.  
ACFS-9309: ADVM/ACFS installation correctness verified.  
**\[root@ocm1 ~\]\# /u01/11.2.0/grid/bin/acfsload start**  
ACFS-9327: Verifying ADVM/ACFS devices.  
ACFS-9322: done.  
\[root@ocm1 ~\]\# /u01/11.2.0/grid/bin/acfsload start -s  
\[root@ocm1 ~\]\# lsmod |grep oracle  
oracleacfs            787460  0   
oracleadvm            177792  0   
oracleoks             226656  2 oracleacfs,oracleadvm  
oracleasm              46356  1   
**\[root@ocm1 ~\]\# cat /etc/init.d/acfsload **  
\#!/bin/bash  
\# chkconfig: 2345 30 21  
\# description: Load Oracle ASM Volume driver on system startup  
export ORACLE\_HOME=/u01/11.2.0/grid  
$ORACLE\_HOME/bin/acfsload start -s  
  
**编写ACFS service启动脚本  
\[root@ocm1 ~\]\# chmod 755 /etc/init.d/acfsload   
\[root@ocm1 ~\]\# chkconfig --add acfsload  
\[root@ocm1 ~\]\# chkconfig --list acfsload**  
acfsload        0:off   1:off   2:on    3:on    4:on    5:on    6:off  
  
**建立ACFS文件系统：**

**通过ASMCA可以创建动态卷和ACFS:**

**![Center 1][]**

**1、创建动态卷**  
**SQL> alter diskgroup dg1 add volume acfsvol size 2G;**  
Diskgroup altered.  
  
**2、建立ACFS文件系统**  
\[grid@ocm1 ~\]$ ls /dev/asm  
acfsvol-48  
**\[grid@ocm1 ~\]$  /sbin/mkfs -t acfs -n ACFSVOL1 /dev/asm/acfsvol-48**  
mkfs.acfs: version                   = 11.2.0.1.0.0  
mkfs.acfs: on-disk version           = 39.0  
mkfs.acfs: volume                    = /dev/asm/acfsvol-48  
mkfs.acfs: volume size               = 2147483648  
mkfs.acfs: Format complete.  
**\[grid@ocm1 ~\]$ /sbin/acfsutil registry -a -f /dev/asm/acfsvol-48 /sharedisk/ **  
acfsutil registry: mount point /sharedisk successfully added to Oracle Registry  
  
**通过ASMCA创建ACFS:**  
\[root@ocm1 ~\]\# mkdir /sharedisk  
\[root@ocm1 ~\]\# chown grid:oinstall /sharedisk  
\[root@ocm1 ~\]\# mount.acfs -o all  
\[root@ocm1 ~\]\# df -h  
Filesystem            Size  Used Avail Use% Mounted on  
/dev/mapper/VolGroup00-LogVol00  
                       59G   20G   36G  36% /  
/dev/sda1              99M   12M   82M  13% /boot  
tmpfs                 1.2G  478M  731M  40% /dev/shm  
/dev/asm/acfsvol-48   2.0G   41M  2.0G   2% /sharedisk

**\----- 至此，ACFS创建成功 ！**
