Oracle AutomaticStorage Management Cluster File System (Oracle ACFS) is a multi-platform,scalable file system, and storage management technology that extends OracleAutomatic Storage Management (Oracle ASM) functionality to support customerfiles maintained outside of Oracle Database. Oracle ACFS supports many databaseand application files, including executables,database trace files, databasealert logs, application reports, BFILEs, and configuration files. Othersupported files are video, audio, text, p_w_picpaths, engineering drawings, and othergeneral-purpose application file data.
下面来介绍下11G RAC环境下ACFS的使用，当前系统环境操作系统版本为OEL6.5，数据库版本为ORACLE11204。
1. 查看ACFS相关的服务
查看acfs/advm驱动是否加载
[root@jxcw1 bin]#lsmod |grep oracle
[root@jxcw1 bin]#
[root@jxcw2 bin]#lsmod |grep oracle
[root@jxcw2 bin]#
查看集群资源
[root@jxcw1 ~]# su- grid -c crs_stat|grep acfs
[root@jxcw1 ~]#
[root@jxcw2 ~]# su- grid -c crs_stat|grep acfs
[root@jxcw2 ~]#
使用acfsload加载驱动
[root@jxcw1 bin]#./acfsload start -s
ACFS-9459:ADVM/ACFS is not supported on this OS version: '3.8.13-16.2.1.el6uek.x86_64'
[root@jxcw1 bin]#uname -a
Linux jxcw13.8.13-16.2.1.el6uek.x86_64 #1 SMP Thu Nov 7 17:01:44 PST 2013 x86_64 x86_64x86_64 GNU/Linux
[root@jxcw1 bin]#
从报错信息中可以看出，OEL6.5操作系统11204数据库并未被支持。升级数据库版本，打补丁11204.7后驱动可以被加载，但不能被系统自动加载。处理如下:
[root@jxcw1 ~]# cat/etc/init.d/acfsload
#!/bin/sh
# chkconfig: 234530 21
# description: LoadOracle ASM volume driver on system startup
ORACLE_HOME=/u01/app/11.2.0/grid
export ORACLE_HOME
$ORACLE_HOME/bin/acfsloadstart -s
[root@jxcw1 ~]# chkconfigadd acfsload
[root@jxcw1 ~]#chkconfig --list|grep acfsload
acfsload 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@jxcw1 ~]#
[root@jxcw1 bin]#./acfsload start -s
[root@jxcw1 bin]#lsmod |grep oracle
oracleacfs 877320 0
oracleadvm 221760 0
oracleoks 276880 2 oracleacfs,oracleadvm
[root@jxcw2bin]# lsmod |grep oracle
oracleacfs 877192 0
oracleadvm 221504 0
oracleoks 277008 2 oracleacfs,oracleadvm
[root@jxcw2 bin]#
添加资源ora.registry.acfs
[root@jxcw1 ~]#/u01/app/11.2.0/grid/bin/crsctl add type ora.registry.acfs.type -basetypeora.local_resource.type -file/u01/app/11.2.0/grid/crs/template/registry.acfs.type
[root@jxcw1 ~]# /u01/app/11.2.0/grid/bin/crsctladd resource ora.registry.acfs -attrACL=\'owner:root:rwx,pgrp:oinstall:r-x,other::r--\' -typeora.registry.acfs.type -f
[root@jxcw1 ~]#
查看是否添加成功
[root@jxcw1 ~]# su- grid -c crs_stat | grep acfs
NAME=ora.registry.acfs
TYPE=ora.registry.acfs.type
[root@jxcw1 ~]#
[root@jxcw2 ~]# su- grid -c crs_stat | grep acfs
NAME=ora.registry.acfs
TYPE=ora.registry.acfs.type
[root@jxcw2 ~]#
查看添加的资源状态。

添加的ora.registry.acfs资源默认offline，需手工启动。
[grid@jxcw1 ~]$crsctl start resource ora.registry.acfs -n jxcw1
CRS-2672:Attempting to start 'ora.registry.acfs' on 'jxcw1'
CRS-2676: Start of'ora.registry.acfs' on 'jxcw1' succeeded

2. 使用ASMCMD命令创建ACFS
（1）、使用volcreate命令创建vol01，大小为30G;
ASMCMD>volcreate -G data -s 30G testvol
（2）、使用volinfo查看vol01的相关信息
ASMCMD> volinfo-G data testvol
Diskgroup Name:DATA
Volume Name: TESTVOL
Volume Device: /dev/asm/testvol-347
State: ENABLED
Size (MB): 30720
Resize Unit (MB): 32
Redundancy: UNPROT
Stripe Columns: 4
Stripe Width (K): 128
Usage:
Mountpath:
ASMCMD>
（2）、使用操作系统命令查看设备名，这里的/dev/asm/ testvol-347相当于裸设备。
[grid@jxcw1 ~]$ cd/dev/asm/
[grid@jxcw1 asm]$ls -l
total 0
brwxrwx--- 1 rootasmadmin 251, 177665 Oct 28 13:20 testvol-347
[grid@jxcw1 asm]$
（3）、在v$asm_volume视图中使用sql查看volume相关信息
[grid@jxcw1 asm]$sqlplus / as sysasm

---------------------------------------------------------
TESTVOL /dev/asm/testvol-347 30720
SQL>
（4）、格式化卷，创建文件系统
[root@jxcw1 ~]#mkfs.acfs /dev/asm/testvol-347
mkfs.acfs:version = 11.2.0.4.0
mkfs.acfs: on-diskversion = 39.0
mkfs.acfs:volume =/dev/asm/testvol-347
mkfs.acfs: volumesize = 32212254720
mkfs.acfs: Formatcomplete.
[root@jxcw1 ~]#
（5）、注册ACFS文件系统，相当于定义挂载点，仅在节点1注册一次即可
[root@jxcw1~]#acfsutil registry -a /dev/asm/testvol-347/u01/app/grid/acfsmounts/data_testvol/
acfsutil registry:mount point /u01/app/grid/acfsmounts/data_testvol successfully added to OracleRegistry
查看文件系统信息
[root@jxcw1 ~]#acfsutil info fs

[root@jxcw1 ~]#
（6）、注册成功后自动挂载文件系统，两节点查看如下：
[root@jxcw1 ~]# df-h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root 532G 34G 476G 7% /
tmpfs 16G 255M 16G 2% /dev/shm

[root@jxcw2 ~]#
图形界面查看状态如下
再次查看集群资源状态
[grid@jxcw1 ~]$crsctl stat res -t

3. asmca图形界面创建
切换到grid用户下，执行asmca启动图形界面进行配置
启动图形界面后，点击asm instance可以看到advm driver状态为loaded。若acfs与advm驱动未加载时，状态为installed，volumes与asmcluster file systems标签栏为灰色无法点击。点击volumes标签，创建卷。
图中为使用命令创建成功的卷。再次点击create
指定卷名为jxcwvol，大小为25G,点击OK。
创建成功，点击ok退出，显示如下：
点击asm clusterfile systems标签
点击create,选择刚才创建的卷，选择database home file system选项，并指定图中所示挂载点。选择该选项该文件系统将作为集群资源被注册在集群中，由集群进行管理。
点击ok，创建ACFS文件系统。点击ok执行的命令如下
Create ACFSCommand:
/sbin/mkfs -t acfs/dev/asm/jxcw-347
Following commandsshould be run as privileged user :
/u01/app/11.2.0/grid/bin/srvctladd filesystem -d /dev/asm/jxcw-347 -g 'DATA' -v jxcwvol -m/u01/app/grid/acfsmounts/data_jxcwvol -u grid
/u01/app/11.2.0/grid/bin/srvctlstart filesystem -d /dev/asm/jxcw-347
chown grid:oinstall/u01/app/grid/acfsmounts/ data_jxcwvol
chmod 775/u01/app/grid/acfsmounts/data_jxcwvol
根据提示使用root账户在ASMCA图形界面启动的节点上执行途中所示命令，如下：
[root@jxcw1 ~]#/u01/app/grid/cfgtoollogs/asmca/scripts/acfs_script.sh
ACFS file system isrunning on jxcw1,jxcw2
[root@jxcw1 ~]#
备注：途中所执行脚本内容如下：
[root@jxcw1 ~]# vi/u01/app/grid/cfgtoollogs/asmca/scripts/acfs_script.sh
#!/bin/sh
/u01/app/11.2.0/grid/bin/srvctlstop filesystem -d /dev/asm/jxcwvol-347
/u01/app/11.2.0/grid/bin/srvctlremove filesystem -d /dev/asm/jxcwvol-347
/u01/app/11.2.0/grid/bin/srvctladd filesystem -d /dev/asm/jxcwvol-347 -g 'DATA' -v JXCWVOL -m/u01/app/grid/acfsmounts/data_jxcwvol -u grid
if [ $? ="0" -o $? = "2" ]; then
/u01/app/11.2.0/grid/bin/srvctl startfilesystem -d /dev/asm/jxcwvol-347
if [ $? = "0" ]; then
chown grid:oinstall/u01/app/grid/acfsmounts/data_jxcwvol
chmod 775/u01/app/grid/acfsmounts/data_jxcwvol
/u01/app/11.2.0/grid/bin/srvctl statusfilesystem -d /dev/asm/jxcwvol-347
exit 0
fi
/u01/app/11.2.0/grid/bin/srvctl statusfilesystem -d /dev/asm/jxcwvol-347
fi
执行成功在两节点分别查看，新加ACFS文件系统已被挂载。
[root@jxcw1 ~]# df-h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root 532G 34G 476G 7% /
tmpfs 16G 258M 16G 2% /dev/shm

/dev/asm/jxcwvol-347 25G 128M 25G 1% /u01/app/grid/acfsmounts/data_jxcwvol
[root@jxcw1 ~]#
[root@jxcw2 ~]# df-h

/dev/asm/jxcwvol-347 25G 128M 25G 1% /u01/app/grid/acfsmounts/data_jxcwvol
[root@jxcw2 ~]#
再次看集群资源状态，新创建的ACFS文件系统被作为资源加入集群。
[grid@jxcw1 ~]$crsctl stat res -t
