LVM删除、新增

jtyhrew222

                      之前新加了个pkg,跟上一个删除新增略有不同。


下面是整个步骤

1.停止oracle rac、停止pkg  
节点1操作(root用户)
[iyunv@cmsdb1]#cd /oracle/app/oracle/p*/crs/bin
[iyunv@cmsdb1]#./crs_stop -all
[iyunv@cmsdb1]#./crsctl stop crs
节点2操作(root用户)
[iyunv@cmsdb2]#./crsctl stop crs

全部关闭后，关闭pkg. 节点1操作(root用户)
[iyunv@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
[iyunv@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操作（root用户）
[iyunv@cmsdb1]# vgchange -a n /dev/vgdata
Volume group "/dev/vgdata" has been successfully changed.
[iyunv@cmsdb1]# vgchange -S n -c n /dev/vgdata
Configuration change completed.
Volume group "/dev/vgdata" has been successfully changed.
[iyunv@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。
删除：
[iyunv@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：
[iyunv@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
[iyunv@cmsdb1]# chown -R oracle:dba /dev/vgdata
[iyunv@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）
[iyunv@cmsdb1]#vgchange -a n /dev/vgdata
Volume group "/dev/vgdata" has been successfully changed.
[iyunv@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.
[iyunv@cmsdb1]# rcp /tmp/vgdata.map cmsdb2:/tmp/vgdata.map
[iyunv@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
[iyunv@cmsdb2]#vgexport /dev/vgdata
新建
[iyunv@cmsdb2]# mkdir /dev/vgdata
[iyunv@cmsdb2]# mknod /dev/vgdata/group c 64 0x050000
导入
[iyunv@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
[iyunv@cmsdb1]# chown -R oracle:dba /dev/vgdata
[iyunv@cmsdb1]# chmod -R 660 /dev/vgdata

6.以GX模式激活卷组
节点1执行
[iyunv@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
[iyunv@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
[iyunv@cmsdb1]# cmrunpkg -v pkg1
Running package pkg1 on node cmsdb1
Successfully started package pkg1 on node cmsdb1
cmrunpkg: All specified packages are running
[iyunv@cmsdb1]# cmrunpkg -v pkg2
Running package pkg2 on node cmsdb2
Successfully started package pkg2 on node cmsdb2
cmrunpkg: All specified packages are running
[iyunv@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
[iyunv@cmsdb1]# cd /oracle/app/oracle/p*/crs/bin
[iyunv@cmsdb1]# ./crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly
[iyunv@cmsdb2]# cd /oracle/app/oracle/p*/crs/bin
[iyunv@cmsdb2]# ./crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly

检查集群状态
[iyunv@cmsdb1]# ./crs_stat -t
Name           Type           Target    State     Host

9.结束！
