文档课题：rhel配置ACFS集群文件系统.
环境介绍：
OS：rhel 7.9 64位
架构：rac 双节点
数据库：oracle 11.2.0.4
1、配置前信息
如下所示，在安装好p31718723_112040_Linux-x86-64.zip补丁后，asm cluster file systems和volumes选项卡正常显示，当前已添加磁盘组ACFS，现在目标是创建ASM集群文件系统.
2、ACFS创建步骤
2.1、配置acfsload进程开机自启
说明：两个节点均需执行.
[root@rac1 ~]# vi /etc/init.d/acfsload
#!/bin/bash
# chkconfig: 2345 30 21
# description: Load Oracle ASM volume driver on system startup
ORACLE_HOME=/u01/app/11.2.0/grid
export ORACLE_HOME
$ORACLE_HOME/bin/acfsload start -s
[root@rac1 init.d]# chmod 755 /etc/init.d/acfsload
[root@rac1 init.d]# chkconfig --add acfsload
[root@rac1 init.d]# chkconfig --list | grep acfsload
Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.
If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.
acfsload 0:off 1:off 2:on 3:on 4:on 5:on 6:off
2.2、添加ora.registry.acfs到ocr配置
说明：该步骤仅需在节点1执行.
[root@rac1 init.d]# /u01/app/11.2.0/grid/bin/crsctl add type ora.registry.acfs.type -basetype ora.local_resource.type -file /u01/app/11.2.0/grid/crs/template/registry.acfs.type
[root@rac1 init.d]# /u01/app/11.2.0/grid/bin/crsctl add resource ora.registry.acfs -attr ACL=\'owner:root:rwx,pgrp:oinstall:r-x,other::r--\' -type ora.registry.acfs.type -f
查看是否添加成功.
[root@rac1 init.d]# su - grid -c crs_stat | grep acfs
NAME=ora.registry.acfs
TYPE=ora.registry.acfs.type
[root@rac2 init.d]# su - grid -c crs_stat | grep acfs
NAME=ora.registry.acfs
TYPE=ora.registry.acfs.type
使用acfsuit命令注册文件系统
[root@rac1 init.d]# /sbin/acfsutil registry
2.3、创建卷
说明：此步骤也在节点1执行.
[grid@rac1 ~]$ sqlplus / as sysasm
SQL*Plus: Release 11.2.0.4.0 Production on Mon Jan 8 23:41:06 2024

Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

SQL> alter diskgroup acfs add volume ogg size 5g;
Diskgroup altered.
SQL> col name for a15
SQL> col state for a15
SQL> select group_number,name,state,type from v$asm_diskgroup;
GROUP_NUMBER NAME STATE TYPE
------------ --------------- --------------- ------------------
1 ACFS MOUNTED EXTERN
2 DATA MOUNTED EXTERN
3 OCR MOUNTED EXTERN
[grid@rac1 ~]$ export DISPLAY=192.168.133.1:0.0
[grid@rac1 ~]$ asmca
说明：此时在Volumns列已成功出现卷OGG.
2.4、格式化为acfs文件系统并挂载
创建/ogg挂载点.
[root@rac1 ~]# mkdir /ogg
[root@rac2 ~]# mkdir /ogg
在节点1格式化为acfs集群文件系统.
[root@rac1 ~]# /sbin/mkfs -t acfs -n ogg /dev/asm/ogg-36
mkfs.acfs: version = 11.2.0.4.0
mkfs.acfs: on-disk version = 39.0
mkfs.acfs: volume = /dev/asm/ogg-36
mkfs.acfs: volume size = 5368709120
mkfs.acfs: Format complete.
[root@rac1 ~]# /sbin/acfsutil registry -a -f /dev/asm/ogg-36 /ogg
acfsutil registry: mount point /ogg successfully added to Oracle Registry
2.5、挂载并验证
[root@rac1 ~]# mount.acfs -o all
[root@rac1 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 894M 0 894M 0% /dev
tmpfs 910M 566M 345M 63% /dev/shm

[root@rac1 ~]# /sbin/acfsutil info fs

说明：如上所示，新建的ASM集群文件成功被挂载到/ogg挂载点.
