Centos6.9安装ACFS

安装完oracle 11GR2的RAC后，使用asmca打开图形化界面后，发现Volumes和ASM Cluster File System两个选项卡不能用

原因是因为ACFS不支持CentOS

解决方法

1.查看ACFS是否支持当前操作系统

[grid@rac02 ~]$ acfsdriverstate -orahome $ORACLE_HOME supported

2.修改osds_acfslib.pm文件（RAC所有节点）

# cp -p osds_acfslib.pm osds_acfslib.pm.bak
# vi osds_acfslib.pm
-----------------------------------------------------------------------------
if ((defined($release)) &&                     # Redhat or OEL if defined
      (($release =~ /^redhat-release/) ||        # straight RH
       ($release =~ /^enterprise-release/) ||    # Oracle Enterprise Linux
       ($release =~ /^oraclelinux-release/)))    # Oracle Linux
修改为
if ((defined($release)) &&                     # Redhat or OEL if defined
      (($release =~ /^redhat-release/) ||        # straight RH
       ($release =~ /^enterprise-release/) ||    # Oracle Enterprise Linux
       ($release =~ /^centos-release/) ||        # Centos Linux
       ($release =~ /^oraclelinux-release/)))    # Oracle Linux
-----------------------------------------------------------------------------

3.安装acfs（RAC所有节点）

# cd /grid/home/bin/
# ./acfsload start -s
----------------------------------------------------
ACFS-9129: ADVM/ACFS not installed
----------------------------------------------------
# ./acfsroot install
# ./acfsload start -s
# lsmod |grep oracle
----------------------------------------------------
oracleacfs           1990406  2
oracleadvm            250040  6
oracleoks             427672  2 oracleacfs,oracleadvm
----------------------------------------------------

4.添加ora.registry.acfs到ocr中（任一节点即可）

# /grid/home/bin/crsctl add type ora.registry.acfs.type -basetype ora.local_resource.type  -file /grid/home/crs/template/registry.acfs.type
# /grid/home/bin/crsctl add resource ora.registry.acfs -attr ACL=\'owner:root:rwx,pgrp:oinstall:r-x,other::r--\' -type ora.registry.acfs.type -f
# su - grid -c crs_stat | grep acfs 
----------------------------------------------------
NAME=ora.registry.acfs
TYPE=ora.registry.acfs.type
----------------------------------------------------
#/sbin/acfsutil registr

5.创建Volumes

[grid@rac01 ~]$ export DISPLAY=10.206.132.253:0.0
$ asmca

6.创建ASM Cluster File System并挂载

两个节点创建目录

# mkdir /oggdata
# chown -R oracle.oinstall /oggdata/

挂载

点击OK后报错

ASM Cluster File System creation on /dev/asm/ogg_vol-471 failed with the following message:
mkfs.acfs: ACFS-01010: Volume already contains an ACFS file system.  To reformat the volume, reissue mkfs.acfs with the -f option.
mkfs.acfs: ACFS-01004: /dev/asm/ogg_vol-471 was not formatted.

此时点击Show Command，手动挂载

# /sbin/mkfs -t acfs /dev/asm/ogg_vol-471
# /sbin/acfsutil registry -a -f /dev/asm/ogg_vol-471 /oggdata
报错
------------------------------------------------------------------------------------
[root@rac01 ~]# /sbin/mkfs -t acfs /dev/asm/ogg_vol-471
mkfs.acfs: version                   = 11.2.0.4.0
mkfs.acfs: on-disk version           = 39.0
mkfs.acfs: volume                    = /dev/asm/ogg_vol-471
mkfs.acfs: ACFS-01010: Volume already contains an ACFS file system.  To reformat the volume, reissue mkfs.acfs with the -f option.
mkfs.acfs: ACFS-01004: /dev/asm/ogg_vol-471 was not formatted.
[root@rac01 ~]# /sbin/acfsutil registry -a -f /dev/asm/ogg_vol-471 /oggdata
acfsutil registry: ACFS-03161: Device : /dev/asm/ogg_vol-471 : Mount Point : /oggdata already exis
------------------------------------------------------------------------------------

已经有文件系统且注册，此时直接挂载即可（两个节点都要执行）

# mount.acfs -o all

查看挂载目录信息

# /sbin/acfsutil info fs

7.重启系统，查看是否会挂载

# su - grid
$ crsctl status resource -t
-----------------------------------------------------------------------------
ora.registry.acfs
               ONLINE  OFFLINE      rac01
               ONLINE  OFFLINE      rac02
------------------------------------------------------------------------------

可以看到重启后，acfs为offline状态并且目录页没有挂载

解决方法

两个节点开启acfs
# cd /grid/home/bin
# ./acfsload start -s
任一一个节点开启资源
# ./crsctl start res ora.registry.acfs

根据以上的实践，我们需要acfs加入开机自启动（两个节点）

#  vi /etc/init.d/acfsload
-------------------------------------------------------------------------
#!/bin/sh
# description: Load Oracle ASM volume driver on system startup
ORACLE_HOME=/grid/home
export ORACLE_HOME
$ORACLE_HOME/bin/acfsload start -s
-------------------------------------------------------------------------
# chmod u+x /etc/rc.d/init.d/acfsload
# chkconfig acfsload on

再次重启系统后，acfs资源自动启动，目录也自动挂载
