Oracle-ACFS模块安装

1、前言

从11gR2版本开始引入新特性acfs，可以从asm磁盘组分配一个卷出来格式化成文件系统进行使用，可以用来安装一些辅助工具软件ogg、shareplex或者存放备份数据rman备份集dump文件等等。
默认情况下acfs模块是没有配置的

模块检查

[root@node01 ~]# lsmod | grep oracle
[root@node01 ~]# 

[root@node02 ~]# lsmod | grep oracle
[root@node02 ~]# 

Note：可以看到没有任何的模块信息

2、安装模块

节点1

[root@node01 ~]# cd /u01/app/11.2.0/grid/bin
[root@node01 bin]# ./acfsroot install

[root@node01 bin]# 

节点2

[root@node02 lib]# cd /u01/app/11.2.0/grid/bin
[root@node02 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-9156: Detecting control device '/dev/ofsctl'.
ACFS-9309: ADVM/ACFS installation correctness verified.
[root@node02 bin]# 

3、模块检查

[root@node01  bin]# lsmod |grep oracle
oracleacfs           1990406  0 
oracleadvm            250040  0 
oracleoks             427672  2 oracleacfs,oracleadvm
[root@node01 bin]# 

[root@node02 bin]# lsmod |grep oracle
oracleacfs           1990406  0 
oracleadvm            250040  0 
oracleoks             427672  2 oracleacfs,oracleadvm
[root@node02 bin]# 

4、模块启动

节点1

[root@node01  bin]# ./acfsload start
ACFS-9391: Checking for existing ADVM/ACFS installation.
ACFS-9392: Validating ADVM/ACFS installation files for operating system.
ACFS-9393: Verifying ASM Administrator setup.
ACFS-9308: Loading installed ADVM/ACFS drivers.
ACFS-9327: Verifying ADVM/ACFS devices.
ACFS-9156: Detecting control device '/dev/asm/.asm_ctl_spec'.
ACFS-9156: Detecting control device '/dev/ofsctl'.
ACFS-9322: completed
[root@node01  bin]# 

节点2

[root@node02 bin]# ./acfsload start
ACFS-9391: Checking for existing ADVM/ACFS installation.
ACFS-9392: Validating ADVM/ACFS installation files for operating system.
ACFS-9393: Verifying ASM Administrator setup.
ACFS-9308: Loading installed ADVM/ACFS drivers.
ACFS-9327: Verifying ADVM/ACFS devices.
ACFS-9156: Detecting control device '/dev/asm/.asm_ctl_spec'.
ACFS-9156: Detecting control device '/dev/ofsctl'.
ACFS-9322: completed
[root@node02 bin]# 

5、注册集群资源

[root@node01 bin]# ./acfsroot enable
ACFS-9376: Adding ADVM/ACFS drivers resource succeeded.
CRS-2672: Attempting to start 'ora.drivers.acfs' on 'node01'
CRS-2676: Start of 'ora.drivers.acfs' on 'node01' succeeded
ACFS-9380: Starting ADVM/ACFS drivers resource succeeded.
ACFS-9368: Adding ACFS registry resource succeeded.
CRS-2672: Attempting to start 'ora.registry.acfs' on 'node02'
CRS-2672: Attempting to start 'ora.registry.acfs' on 'node01'
CRS-2676: Start of 'ora.registry.acfs' on 'node01' succeeded
CRS-2676: Start of 'ora.registry.acfs' on 'node02' succeeded
ACFS-9372: Starting ACFS registry resource succeeded.
[root@node01 bin]# 

[grid@node01 ~]$ crsctl stat res -t
                             
ora.registry.acfs
               ONLINE  ONLINE       node01 
               ONLINE  ONLINE       node02

至此ACFS的模块安装就完成了，后续就可以进行acfs卷的创建、格式化、挂载等操作

6、测试模块
