LVM修改

之前新加了个pkg,跟上一个***新增略有不同。

下面是整个步骤

1.停止oracle rac、停止pkg  

节点1执行(root用户)

[root@cmsdb1]#cd /oracle/app/oracle/p*/crs/bin

[root@cmsdb1]#./crs_stop -all

[root@cmsdb1]#./crsctl stop crs

节点2执行(root用户)

[root@cmsdb2]#./crsctl stop crs

全部关闭后，关闭pkg. 节点1执行(root用户)

[root@cmsdb1]#cmhaltpkg -v pkg1

Halting package pkg1 on node cmsdb1

Successfully halted package pkg1 on node cmsdb1

One or more packages or package instances have been halted.

cmhaltpkg: Completed successfully on all packages specified

[root@cmsdb1]#cmhaltpkg -v pkg2

Halting package pkg2 on node cmsdb2

Successfully halted package pkg2 on node cmsdb2

One or more packages or package instances have been halted.

cmhaltpkg: Completed successfully on all packages specified

2.停用卷组，将卷组集群更改为不可用，激活卷组（非GX）

节点1执行（root用户）

[root@cmsdb1]# vgchange -a n /dev/vgdata

Volume group "/dev/vgdata" has been successfully changed.

[root@cmsdb1]# vgchange -S n -c n /dev/vgdata

Configuration change completed.

Volume group "/dev/vgdata" has been successfully changed.

[root@cmsdb1]# vgchange -a y /dev/vgdata

Activated volume group.

Volume group "/dev/vgdata" has been successfully changed.

3.使用标准LVM命令进行所需的更改。一定要设置的原始逻辑卷设备文件的所有者为oracle，组设为dba，模式为660。

delete：

[root@cmsdb1]# lvremove /dev/vgdata/Lvdata1_50g

The logical volume "/dev/vgdata/Lvdata1_50g" is not empty;

do you really want to delete the logical volume (y/n) : y

Logical volume "/dev/vgdata/Lvdata1_50g" has been successfully removed.

Volume Group configuration for /dev/vgdata has been saved in /etc/lvmconf/vgdata.conf

新增：

[root@cmsdb1]# lvcreate -L 10240 -n Lvdata01_10g /dev/vgdata 

Logical volume "/dev/vgdata/Lvdata01_10g" has been successfully created with

character device "/dev/vgdata/rLvdata01_10g".

Logical volume "/dev/vgdata/Lvdata01_10g" has been successfully extended.

Volume Group configuration for /dev/vgdata has been saved in /etc/lvmconf/vgdata.conf

修改属组、授权

[root@cmsdb1]# chown -R oracle:dba /dev/vgdata

[root@cmsdb1]# chmod -R 660 /dev/vgdata

4.停用卷组，导出map文件，拷贝至节点2，GX群组

节点1（root用户）

[root@cmsdb1]#vgchange -a n /dev/vgdata

Volume group "/dev/vgdata" has been successfully changed.

[root@cmsdb1]#vgexport -p -s -v -m /tmp/vgdata.map /dev/vgdata

Beginning the export process on Volume Group "/dev/vgdata".

/dev/disk/disk7

vgexport: Preview of vgexport on volume group "/dev/vgdata" succeeded.

[root@cmsdb1]# rcp /tmp/vgdata.map cmsdb2:/tmp/vgdata.map 

[root@cmsdb1]# vgchange -S y -c y /dev/vgdata

Configuration change completed.

Volume group "/dev/vgdata" has been successfully changed.

5.节点2重新导入map文件、修改属组、授权

导出

[root@cmsdb2]#vgexport /dev/vgdata

新建

[root@cmsdb2]# mkdir /dev/vgdata 

[root@cmsdb2]# mknod /dev/vgdata/group c 64 0x050000

导入

[root@cmsdb2]# vgimport -s -v -m /tmp/vgdata.map /dev/vgdata 

Beginning the import process on Volume Group "/dev/vgdata". 

Logical volume "/dev/vgdata/Lvdata01_10g" has been successfully created 

with lv number 1. 

修改属组、授权

[root@cmsdb1]# chown -R oracle:dba /dev/vgdata

[root@cmsdb1]# chmod -R 660 /dev/vgdata

6.以GX模式激活卷组

节点1执行

[root@cmsdb1]# vgchange -a s -p /dev/vgdata

Activated volume group in Shared Mode.

This node is the Server.

Volume group "/dev/vgdata" has been successfully changed.

节点2执行

[root@cmsdb2]# vgchange -a s -p /dev/vgdata

Activated volume group in Shared Mode.

This node is the Server.

Volume group "/dev/vgdata" has been successfully changed.

7.开启pkg

[root@cmsdb1]# cmrunpkg -v pkg1

Running package pkg1 on node cmsdb1

Successfully started package pkg1 on node cmsdb1

cmrunpkg: All specified packages are running

[root@cmsdb1]# cmrunpkg -v pkg2

Running package pkg2 on node cmsdb2

Successfully started package pkg2 on node cmsdb2

cmrunpkg: All specified packages are running

[root@cmsdb1]# cmviewcl

CLUSTER        STATUS       

cmsdb          up           

  

  NODE           STATUS       STATE        

  cmsdb1         up           running      

  cmsdb2         up           running      

  

MULTI_NODE_PACKAGES

  PACKAGE        STATUS           STATE            AUTO_RUN    SYSTEM      

  pkg1           up               running          enabled     no          

  pkg2           up               running          enabled     no         

  

8.启动oracle rac

节点1、2均执行

[root@cmsdb1]# cd /oracle/app/oracle/p*/crs/bin

[root@cmsdb1]# ./crsctl start crs

Attempting to start CRS stack 

The CRS stack will be started shortly

[root@cmsdb2]# cd /oracle/app/oracle/p*/crs/bin

[root@cmsdb2]# ./crsctl start crs

Attempting to start CRS stack 

The CRS stack will be started shortly

检查集群状态

[root@cmsdb1]# ./crs_stat -t

Name           Type           Target    State     Host
