Oracle数据库集群管理-RAC 安装19.1OGG之配置ACFS

一:ADVM与ACFS简单介绍

ADVM: ACFS文件系统使用的一种卷格式.

ACFS: Oracle提供的基于ASM的共享文件系统,其扩展了Oracle ASM的功能.可以存放更多类型的文件.

Oracle ACFS通过Oracle ADVM接口与Oracle ASM通信。

1 创建磁盘组 或者使用已有的磁盘组。

2 创建vol

3 创建ACFS并且挂载

因为要安装RAC的ogg，这里先安装ACFS

RAC版本为19c
OGG版本为19.1
平台为VMware
操作系统为 Red Hat Enterprise Linux Server release 7.2

查看内核是否加载ACFS模块
[eoms@orcldb2 ~]$ lsmod|grep acfs
oracleacfs           5921415  2 
oracleoks             750688  2 oracleacfs,oracleadvm

查看内核是否加载ADVM模块
[eoms@orcldb2 ~]$ lsmod|grep advm
oracleadvm           1236257  8 
oracleoks             750688  2 oracleacfs,oracleadvm

Purpose
acfsload loads or unloads Oracle ACFS, Oracle ADVM, and Oracle Kernel Services
Driver (OKS) drivers.
Syntax
acfsload { start | stop } [ -s ]

1、首先创建共享盘

 2、分别添加到RAC的两个节点中

 添加如下几行

3、使用udev绑定

查看新添加的磁盘

or i in e;
do
echo "KERNEL==\"sd*\",ENV{DEVTYPE}==\"disk\",SUBSYSTEM==\"block\",PROGRAM==\"/usr/lib/udev/scsi_id -g -u -d \$devnode\",RESULT==\"`/usr/lib/udev/scsi_id -g -u /dev/sd$i`\", RUN+=\"/bin/sh -c 'mknod /dev/asmdisk$i b  \$major \$minor; chown grid:asmadmin /dev/asmdisk$i; chmod 0660 /dev/asmdisk$i'\""
done
绑定前记录/etc/udev/rules.d/99-oracle-asmdevices.rules 文件内容

[root@dm01 ~]# cat /etc/udev/rules.d/99-oracle-asmdevices.rules 
KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",RESULT=="36000c29646b3175cadf174105bf96e66", RUN+="/bin/sh -c 'mknod /dev/asmdiskb b  $major $minor; chown grid:asmadmin /dev/asmdiskb; chmod 0660 /dev/asmdiskb'"

[root@dm01 ~]# 

绑定(RAC的两个节点都要执行)，把得到记录追加到/etc/udev/rules.d/99-oracle-asmdevices.rules

[root@dm01 ~]# for i in e;

[root@dm01 ~]# 

但是发现并没有生成期望的asmdiske

[root@dm01 dev]# cd /dev/
[root@dm01 dev]# ls -ltr asm*
brw-rw---- 1 grid asmadmin 8, 48 Jan  5 15:00 asmdiskd
brw-rw---- 1 grid asmadmin 8, 16 Jan  5 15:48 asmdiskb
brw-rw---- 1 grid asmadmin 8, 32 Jan  5 15:48 asmdiskc
 
asm:

[root@dm01 dev]# 

重新加载udev

[root@dm01 dev]# /sbin/udevadm trigger --type=devices --action=change
[root@dm01 dev]# /sbin/udevadm control --reload
[root@dm01 dev]# ls -ltr asm*

[root@dm01 dev]# 

还是看不到，重启节点之后还是不行，最后决定手动创建了（RAC的2个节点都执行）

[root@dm01 dev]# ls -ltr /dev/sd*

4、使用asmca创建磁盘组

首先要创建ASM磁盘组，然后在此基础上创建ASM卷，最后才能创建ACFS

首先创建磁盘组

4.1)选中Disk Groups，点击左下角的create

 4.2）选项External，磁盘组名字为OGG，选择刚创建的/dev/asmdiske磁盘

 4.3)点击OK，开始创建磁盘组

 4.4)OGG磁盘组创建成功

 4.5)使用crsctl命令检查crsctl stat res -t

5、使用asmca创建acfs

5.1）grid用户调用asmca(RAC的任意一个节点)

 5.2) 选中Volumes

 5.3) 输入volume名字，选择磁盘组OGG，大小给4G，点击OK

 5.4）volumes创建成功

 5.5)创建ACFS，选中ACFS File Systems，点击create

5.6) 两节点首先创建好/ogg目录，然后勾选自动运行配置命令，点击OK

[root@dm01 dev]# mkdir -p /ogg
[root@dm01 dev]# chown -R oracle:oinstall /ogg

 遇到DBT-30145 You need to enter the root credentials in 'Settings' for ASMCA

 把自动运行勾选去掉，先show command显示如下：

 

 5.7）运行acfs_script.sh脚本

 [grid@dm02 ~]$ /u01/app/grid/cfgtoollogs/asmca/scripts/acfs_script.sh 
PRCN-2018 : Current user grid is not a privileged user

2 实战案例脚本安装
 

2.1 19C集群对应的资源如下：

[grid@orcldb2 ~]$ crsctl status res -t|grep acfs
ora.ogg.vologg.acfs
[grid@orcldb2 ~]$ crsctl status res -t|grep advm
ora.OGG.VOLOGG.advm
ora.proxy_advm
[grid@orcldb2 ~]$ 

2.2 使用ASMCMD创建

官方文档：

Creating an Oracle ACFS File System

You can create an Oracle ACFS file system using the steps in this topic.

To create and verify a file system, perform the following steps:

1. Create an Oracle ADVM volume in a mounted disk group with the ASMCMD volcreate command.

   The compatibility parameters COMPATIBLE.ASM and COMPATIBLE.ADVM must be set to 11.2 or higher for the disk group to contain an Oracle ADVM volume. To use Oracle ACFS encryption, replication, security, or tagging, the disk group on which the volume is created for the file system must have compatibility attributes for ASM and ADVM set to 11.2.0.2 or higher.

   Start ASMCMD connected to the Oracle ASM instance. You must be a user in the OSASM operating system group.

   When configuring Oracle ADVM volume devices within a disk group, Oracle recommends assigning the Oracle Grid Infrastructure user and Oracle ASM administrator roles to users who have root privileges.

   To create a volume:

   Copy

   ASMCMD [+] > volcreate -G data -s 10G volume1

   When creating an Oracle ADVM volume, a volume device name is created that includes a unique Oracle ADVM persistent disk group number. The volume device file functions in the same manner as any other disk or logical volume to mount file systems or for applications to use directly.

   The format of the volume name is platform-specific.

2. Determine the device name of the volume that was created.

   You can determine the volume device name with the ASMCMD volinfo command or from the VOLUME_DEVICE column in the V$ASM_VOLUME view.

   For example:

   Copy

   ASMCMD [+] > volinfo -G data volume1

3. Diskgroup Name: DATA Volume Name: VOLUME1 Volume Device: /dev/asm/volume1-123 State: ENABLED ...

4. SQL> SELECT volume_name, volume_device FROM V$ASM_VOLUME WHERE volume_name ='VOLUME1'; VOLUME_NAME VOLUME_DEVICE ----------------- -------------------------------------- VOLUME1 /dev/asm/volume1-123

5. Create a file system with the Oracle ACFS mkfs command.

   Create a file system using an existing volume device.

   For example:

   $ /sbin/mkfs -t acfs /dev/asm/volume1-123

6. mkfs.acfs: version = 19.0.0.0.0 mkfs.acfs: on-disk version = 46.0 mkfs.acfs: volume = /dev/asm/volume1-123 mkfs.acfs: volume size = 10737418240 ( 10.00 GB ) mkfs.acfs: Format complete.

   The root privilege is not required to run mkfs. The ownership of the volume device file dictates who can run this command.

7. Register the file system.

   In an Oracle Grid Infrastructure Clusterware configuration, you can run the srvctl add filesystem command to register and automount a file system. For example:

   Copy

   # srvctl add filesystem -device /dev/asm/volume1-123 -path /acfsmounts/acfs1
          -user user1,user2,user3 -mtowner sysowner -mtgroup sysgrp -mtperm 755

   You can also register a file system with the acfsutil registry command. For example:

   Copy

   $ /sbin/acfsutil registry -a /dev/asm/volume1-123 /acfsmounts/acfs1

   After registering an Oracle ACFS file system in the cluster mount registry, the file system is mounted automatically on each cluster member listed in the registry entry during the next registry check action. This automatic process runs every 30 seconds and eliminates the requirement to manually mount the file system on each member of the cluster. Registering an Oracle ACFS file system also causes the file system to be mounted automatically whenever Oracle Clusterware or the system is restarted.

   Note:

   • The srvctl add filesystem command is required when an Oracle Database home is installed on an Oracle ACFS file system. In this case, the file system should not be explicitly added to the registry with the Oracle ACFS registration command (acfsutil registry).
   • Oracle ACFS registration is not supported in an Oracle Restart (standalone) configuration, which is a single-instance (non-clustered) environment.
   • The root or asmadmin privileges are required to modify the registry. The Windows Administrator privilege is equivalent to the root privilege on Linux.

8. Mount or start the file system.

   If you have previously registered the file system, then start the file system with SRVCTL. For example:

   Copy

   $ srvctl start filesystem -device /dev/asm/volume1-123

   If you have not previously registered the file system, then mount the file system with the Oracle ACFS mount command. For example:

   Copy

   # /bin/mount -t acfs /dev/asm/volume1-123 /acfsmounts/acf1

   After an unregistered file system has been mounted, ensure that the permissions are set to allow access to the file system for the appropriate users. For example:

   Copy

   # chown -R oracle:dba /acfsmounts/acfs1

   The root privilege is required to run the mount command and the Windows Administrator privilege is required to run the acfsmountvol command.

9. Create a test file in the file system.

   The user that creates the test file should be a user that is intended to access the file system. This test ensures that the appropriate user can write to the file system.

   For example:

   Copy

   $ echo "Oracle ACFS File System" > /acfsmounts/acfs1/myfile

10. List the contents of the test file that was created in the file system.

    For example:

    $ cat /acfsmounts/acfs1/myfile Oracle ACFS File System

Removing an Oracle ACFS File System and a Volume

To permanently remove a volume and Oracle ACFS file system, perform the following steps. These steps destroy the data in the file system.

1. Deregister the file system with acfsutil registry -d.

   For example:

   $ /sbin/acfsutil registry -d /acfsmounts/acfs1
   acfsutil registry: successfully removed ACFS mount point
      /acfsmounts/acfs1 from Oracle Registry
   

   For information about running acfsutil registry, see "acfsutil registry".

2. Dismount the file system.

   For example:

   # /bin/umount /acfsmounts/acfs1
   

   You must dismount the file system on all nodes of a cluster.

   Use umount on Linux systems or acfsdismount on Windows systems. For information about running umount or acfsdismount, see "umount" or "acfsdismount".

3. Remove the file system with acfsutil rmfs.

   If you were not planning to remove the volume in a later step, this step is necessary to remove the file system. Otherwise, the file system is removed when the volume is deleted.

   For example:

   $ /sbin/acfsutil rmfs /dev/asm/volume1-123
   

   For information about running acfsutil rmfs, see "acfsutil rmfs".

4. Optionally you can disable the volume with the ASMCMD voldisable command.

   For example:

   ASMCMD> voldisable -G data volume1
   

   For information about running voldisable, see Managing Oracle ADVM with ASMCMD .

5. Delete the volume with the ASMCMD voldelete command.

   For example:

   ASMCMD> voldelete -G data volume1
   

   For information about running voldelete, see Managing Oracle ADVM with ASMCMD .
