配置Centos上使用ACFS集群文件系统

在centos6.8 64位系统上安装完一套oracle 11.2.0.4 rac测试环境后，发现acfs和advm无法使用，ASMCA图形界面的acfs和volume选项卡为灰色！这是由于acfs不支持centos系统导致的，下面就介绍下如何在配置centos上使用acfs集群文件系统！

**测试环境：**

OS:Centos 6.8

Oracle:11.2.0.4 rac1 rac2 rac3

**1.问题描述：**

\[root@rac1 lib\]\# su - grid  
\+ASM1:/home/grid@rac1>export DISPLAY=192.168.180.186:0.0  
\+ASM1:/home/grid@rac1>asmca

![Center][]

**2：修改osds\_acfslib.pm脚本代码,所有节点都要执行**

\[root@rac1 lib\]\# cd /u01/app/11.2.0/grid\_1/lib/

\[root@rac1 lib\]\# cp -p osds\_acfslib.pm osds\_acfslib.pm.bak

\[root@rac1 lib\]\# vi osds\_acfslib.pm

修改以下内容

if ((defined($release)) &&                     \# Redhat or OEL if defined  
      (($release =~ /^redhat-release/) ||        \# straight RH  
       ($release =~ /^enterprise-release/) ||    \# Oracle Enterprise Linux  
       ($release =~ /^oraclelinux-release/)))    \# Oracle Linux

将上面的代码片段修改如下

if ((defined($release)) &&                     # Redhat or OEL if defined
          (($release =~ /^redhat-release/) ||        # straight RH
           ($release =~ /^enterprise-release/) ||    # Oracle Enterprise Linux
           ($release =~ /^centos-release/) ||         #CentOS hack
           ($release =~ /^oraclelinux-release/)))    # Oracle Linux

**3：安装acfs，配置acfs和advm模块启动自动加载，其他节点做同样的配置**

\[root@rac1 lib\]\# /u01/app/11.2.0/grid\_1/bin/acfsload start -s

ACFS-9129: ADVM/ACFS not installed

\[root@rac1 lib\]\# /u01/app/11.2.0/grid\_1/bin/acfsroot install  
ACFS-9300: ADVM/ACFS distribution files found.  
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-9154: Loading 'oracleoks.ko' driver.  
ACFS-9154: Loading 'oracleadvm.ko' driver.  
ACFS-9154: Loading 'oracleacfs.ko' driver.  
ACFS-9327: Verifying ADVM/ACFS devices.  
ACFS-9156: Detecting control device '/dev/asm/.asm\_ctl\_spec'.  
ACFS-9156: Detecting control device '/dev/ofsctl'.  
ACFS-9309: ADVM/ACFS installation correctness verified.  
\[root@rac1 lib\]\# /u01/app/11.2.0/grid\_1/bin/acfsload start -s  
\[root@rac1 lib\]\# lsmod |grep oracle  
oracleacfs           1990406  0   
oracleadvm            250040  0   
oracleoks             427672  2 oracleacfs,oracleadvm  
  
\[root@rac1 lib\]\# vi /etc/init.d/acfsload

\#!/bin/sh  
\# chkconfig: 2345 30 21  
\# description: Load Oracle ASM volume driver on system startup  
ORACLE\_HOME=/u01/app/11.2.0/grid\_1  
export ORACLE\_HOME  
$ORACLE\_HOME/bin/acfsload start -s

\[root@rac1 lib\]\# chmod 755 /etc/init.d/acfsload   
\[root@rac1 lib\]\# chkconfig --add acfsload  
\[root@rac1 lib\]\# chkconfig --list |grep acfsload  
acfsload       0:off 1:off 2:on 3:on 4:on 5:on 6:off

**4.添加ora.registry.acfs到ocr配置中（在节点1上执行就可以了）**

\[root@rac1 template\]\# /u01/app/11.2.0/grid\_1/bin/crsctl add type ora.registry.acfs.type -basetype ora.local\_resource.type -file /u01/app/11.2.0/grid\_1/crs/template/registry.acfs.type

\[root@rac1 ~\]\# /u01/app/11.2.0/grid\_1/bin/crsctl add resource ora.registry.acfs -attr ACL=\\'owner:root:rwx,pgrp:oinstall:r-x,other::r--\\'  -type ora.registry.acfs.type -f

查看节是否添加成功  
\[root@rac1 ~\]\# su - grid -c crs\_stat | grep acfs   
NAME=ora.registry.acfs  
TYPE=ora.registry.acfs.type

\[root@rac2 ~\]\# su - grid -c crs\_stat | grep acfs   
NAME=ora.registry.acfs  
TYPE=ora.registry.acfs.type

\[root@rac3 ~\]\# su - grid -c crs\_stat | grep acfs   
NAME=ora.registry.acfs  
TYPE=ora.registry.acfs.type

\[root@rac1 ~\]\# /sbin/acfsutil registry

**5.创建卷并格式化成acfs集群文件系统并挂载**  
  
SQL> conn /as sysasm  
Connected.  
SQL> alter diskgroup ACFS add volume acfsvol size 1G;  
  
  
Diskgroup altered.  
  
  
SQL> select group\_number,name,state,type from v$asm\_diskgroup;  
  
  
GROUP\_NUMBER NAME    STATE TYPE  
\------------ ------------------------------ ----------- ------  
  1 DATA     MOUNTED EXTERN  
  2 FRA\_ARC     MOUNTED EXTERN  
  3 OCR\_VOTING\_NEW    MOUNTED NORMAL  
  4 ACFS     MOUNTED EXTERN

这时候查看asmca 可以看到：

**创建共享磁盘：**

root@rac1 ~\]\# mkdir /shareddisk

root@rac2 ~\]\# mkdir /shareddisk

root@rac3 ~\]\# mkdir /shareddisk

\[root@rac1 ~\]\# /sbin/mkfs -t acfs -n acfsvol1  /dev/asm/acfsvol-440   
mkfs.acfs: version                   = 11.2.0.4.0  
mkfs.acfs: on-disk version           = 39.0  
mkfs.acfs: volume                    = /dev/asm/acfsvol-440  
mkfs.acfs: volume size               = 1073741824  
mkfs.acfs: Format complete.

\[root@rac1 ~\]\# /sbin/acfsutil registry -a -f /dev/asm/acfsvol-440 /shareddisk/  
acfsutil registry: mount point /shareddisk successfully added to Oracle Registry

\[root@rac1 ~\]\# mount.acfs -o all
