ORACLE 11G RAC ASM磁盤組全部丟失後的恢復

阿新 • • 發佈：2018-08-16
實例 ice mat dns 禁用 buffers bit allocated event

一、環境描述
（1）Oracle 11.2.0.3 RAC ON Oracle Linux 6 x86_64，只有一個ASM外部冗余磁盤組——DATA；
（2）OCR，VOTEDISK，DATAFILE，CONTROLFILE，SPFILE全部位於這個磁盤組上；
二、故障描述
（1）存儲故障導致ASM磁盤丟失。
（2）CRS因為OCR和VOTEDISK的丟失，除了OHAS還聯機外，CLUSTERWARE服務都已經停止。
三、備份情況
（1）RMAN備份：包括controlfile，database，spfile，archivelog，
（2）OCR備份：沒有進行過人工備份，在$CRS_HOME/cdata目錄下有CRS自動備份文件。

四、操作步驟
說明：準使用CRS自動備份的文件恢復OCR，使用RMAN備份來恢復數據庫；準備恢復數據的同時，調整ASM磁盤組，將OCR，VOTEDISK同數據庫文件分開存放。
4.1 恢復OCR和VOTEDISK
(1) 在所有RAC節點上停止CRS服務
[root@rac1 ~]# crsctl stop has -f
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on ‘rac1‘
CRS-2673: Attempting to stop ‘ora.mdnsd‘ on ‘rac1‘

CRS-2673: Attempting to stop ‘ora.crf‘ on ‘rac1‘
CRS-2677: Stop of ‘ora.mdnsd‘ on ‘rac1‘ succeeded
CRS-2677: Stop of ‘ora.crf‘ on ‘rac1‘ succeeded
CRS-2673: Attempting to stop ‘ora.gipcd‘ on ‘rac1‘
CRS-2677: Stop of ‘ora.gipcd‘ on ‘rac1‘ succeeded
CRS-2673: Attempting to stop ‘ora.gpnpd‘ on ‘rac1‘
CRS-2677: Stop of ‘ora.gpnpd‘ on ‘rac1‘ succeeded
CRS-2793: Shutdown of Oracle High Availability Services-managed resources on ‘rac1‘ has completed
CRS-4133: Oracle High Availability Services has been stopped.
[root@rac2 ~]# crsctl stop has -f

CRS-2677: Stop of ‘ora.gipcd‘ on ‘rac2‘ succeeded
CRS-2673: Attempting to stop ‘ora.gpnpd‘ on ‘rac2‘
CRS-2677: Stop of ‘ora.gpnpd‘ on ‘rac2‘ succeeded
CRS-2793: Shutdown of Oracle High Availability Services-managed resources on ‘rac2‘ has completed
CRS-4133: Oracle High Availability Services has been stopped.
(2) 在一個節點上以NOCRS方式啟動CRS，此操作會啟動ASM實例。
[root@rac1 ~]# crsctl start crs -excl -nocrs
CRS-4123: Oracle High Availability Services has been started.
CRS-2672: Attempting to start ‘ora.mdnsd‘ on ‘rac1‘
CRS-2676: Start of ‘ora.mdnsd‘ on ‘rac1‘ succeeded
CRS-2672: Attempting to start ‘ora.gpnpd‘ on ‘rac1‘
CRS-2676: Start of ‘ora.gpnpd‘ on ‘rac1‘ succeeded
CRS-2672: Attempting to start ‘ora.cssdmonitor‘ on ‘rac1‘
CRS-2672: Attempting to start ‘ora.gipcd‘ on ‘rac1‘
CRS-2676: Start of ‘ora.cssdmonitor‘ on ‘rac1‘ succeeded
CRS-2676: Start of ‘ora.gipcd‘ on ‘rac1‘ succeeded
CRS-2672: Attempting to start ‘ora.cssd‘ on ‘rac1‘
CRS-2672: Attempting to start ‘ora.diskmon‘ on ‘rac1‘
CRS-2676: Start of ‘ora.diskmon‘ on ‘rac1‘ succeeded
CRS-2676: Start of ‘ora.cssd‘ on ‘rac1‘ succeeded
CRS-2679: Attempting to clean ‘ora.cluster_interconnect.haip‘ on ‘rac1‘
CRS-2672: Attempting to start ‘ora.ctssd‘ on ‘rac1‘
CRS-2681: Clean of ‘ora.cluster_interconnect.haip‘ on ‘rac1‘ succeeded
CRS-2672: Attempting to start ‘ora.cluster_interconnect.haip‘ on ‘rac1‘
CRS-2676: Start of ‘ora.ctssd‘ on ‘rac1‘ succeeded
CRS-2676: Start of ‘ora.cluster_interconnect.haip‘ on ‘rac1‘ succeeded
CRS-2672: Attempting to start ‘ora.asm‘ on ‘rac1‘
CRS-2676: Start of ‘ora.asm‘ on ‘rac1‘ succeeded

(3) 新添加了三塊磁盤，已經使用UDEV進行了綁定，查看磁盤狀態。

[root@rac1 ~]# su - grid
[grid@rac1 ~]$ sqlplus / as sysasm

     0          2      20480 NORMAL     /dev/asm-diskb       CANDIDATE

(4) 創建三個磁盤組，SYSTEMDG給CRS使用，用於存放OCR，VOTEDISK和ASM實例的SPFILE。其余兩個給ORACLE使用，DATADG用於存放datafile，controlfile，redolog，spfile；ARCLOGDG存放archivelog。

SQL> create diskgroup SYSTEMDG external redundancy
2 disk ‘/dev/asm-diskc‘
3 ATTRIBUTE ‘compatible.rdbms‘ = ‘11.2‘,‘compatible.asm‘ = ‘11.2‘;

Diskgroup created.

SQL> create diskgroup DATADG external redundancy
2 disk ‘/dev/asm-diskb‘
3 ATTRIBUTE ‘compatible.rdbms‘ = ‘11.2‘,‘compatible.asm‘ = ‘11.2‘;

Diskgroup created.

SQL> create diskgroup ARCLOGDG external redundancy
2 disk ‘/dev/asm-diskd‘
3 ATTRIBUTE ‘compatible.rdbms‘ = ‘11.2‘,‘compatible.asm‘ = ‘11.2‘;

Diskgroup created.

(5) 準備恢復OCR和VOTEDISK，/etc/oracle/ocr.loc中記錄了OCR路徑，修改ocrconfig_loc的值，以便將OCR恢復到新的磁盤組中。

[root@rac1 ~]# more /etc/oracle/ocr.loc
ocrconfig_loc=+DATA
local_only=FALSE

[root@rac1 ~]# vi /etc/oracle/ocr.loc

ocrconfig_loc=+SYSTEMDG
local_only=FALSE

(6) 恢復OCR

[root@rac1 ~]# ocrconfig -showbackup
PROT-26: Oracle Cluster Registry backup locations were retrieved from a local copy

rac1 2013/07/05 12:30:00 /u01/app/11.2.0/grid/cdata/rac-cluster/backup00.ocr

rac1 2013/07/05 08:30:00 /u01/app/11.2.0/grid/cdata/rac-cluster/backup01.ocr

rac1 2013/07/05 00:29:59 /u01/app/11.2.0/grid/cdata/rac-cluster/week.ocr
PROT-25: Manual backups for the Oracle Cluster Registry are not available

[root@rac1 ~]# ocrconfig -restore /u01/app/11.2.0/grid/cdata/rac-cluster/backup00.ocr
[root@rac1 ~]#
[root@rac1 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :

                                Device/File not configured

     Cluster registry integrity check succeeded

     Logical corruption check succeeded

(7) 創建VOTEDISK

[root@rac1 ~]# crsctl replace votedisk +SYSTEMDG
CRS-4602: Failed 27 to add voting file afb0ca0f35684f1abfd43d5ec2dc1123.
Failed to replace voting disk group with +SYSTEMDG.
CRS-4000: Command Replace failed, or completed with errors.

以上報錯是因為使用UDEV綁定ASM磁盤時需要更改默認磁盤搜索路徑為/dev/asm*，修改ASM磁盤搜索路徑

[root@rac1 ~]# su - grid
[grid@rac1 ~]$ sqlplus / as sysasm

在次創建VOTEDISK，成功。

[root@rac1 init]# crsctl replace votedisk +SYSTEMDG
Successful addition of voting disk 8ebb7a63accb4fa8bfa7ab65df7a8c8a.
Successfully replaced voting disk group with +SYSTEMDG.
CRS-4266: Voting file(s) successfully replaced

(8) OCR和VOTEDISK都恢復完成後，重啟CRS到正常模式。

[root@rac1 ~]# crsctl stop has -f

4.2 修改CRS註冊表中相關配置信息

(1) 掛載新的ASM磁盤組

[grid@rac1 ~]$ sqlplus / as sysasm

SQL*Plus: Release 11.2.0.3.0 Production on Sat Jul 6 00:16:05 2013

SQL>
SQL> select name,state from v$asm_diskgroup;

NAME STATE

SYSTEMDG MOUNTED
ARCLOGDG DISMOUNTED
DATADG DISMOUNTED

SQL> alter diskgroup ARCLOGDG,DATADG mount;

Diskgroup altered.

(2) 更改CRS配置文件中數據庫的磁盤組為DATADG和ARCLOGDG

[root@rac1 ~]# srvctl modify database -d csdb -a "DATADG,ARCLOGDG"

(3) 禁用並刪除原來的磁盤組DATA

[root@rac1 ~]# srvctl disable diskgroup -g DATA
[root@rac1 ~]# srvctl remove diskgroup -g DATA

[root@rac1 rac-cluster]# crs_stat -t -v

(4) 在OCR註冊表中修改Oracle數據庫參數文件的位置

[root@rac1 ~]# srvctl modify database -d csdb -p +DATADG/csdb/spfilecsdb.ora

4.3 恢復數據庫

(1) 查看備份文件路徑和名稱

[root@rac1 ~]# su - oracle
[oracle@rac1 ~]$
[oracle@rac1 ~]$ cd /u01/app/oracle/backup
[oracle@rac1 backup]$ ll
total 221796
-rw-r----- 1 oracle asmadmin 5357568 Jul 5 15:19 arc_819991156_9.bk
-rw-r----- 1 oracle asmadmin 2560 Jul 5 15:19 arc_819991158_11.bk
-rw-r----- 1 oracle asmadmin 203104256 Jul 5 15:18 CSDB_819991120_5.bk
-rw-r----- 1 oracle asmadmin 18546688 Jul 5 15:19 ctl_file_0coe04jq_1_1_20130705.ctl
-rw-r----- 1 oracle asmadmin 98304 Jul 5 15:19 spfile_0doe04js_1_1_20130705
[oracle@rac1 backup]$

(2) 創建一個基本的啟動參數文件，以便啟動數據庫到nomout狀態恢復spfile

[oracle@rac1 ~]$ touch /u01/app/oracle/backup/init.ora
[oracle@rac1 ~]$ vi /u01/app/oracle/backup/init.ora

.db_name=‘csdb‘
.remote_login_passwordfile=‘exclusive‘

(3) 使用剛創建的參數文件將數據庫啟動到nomount狀態

[oracle@rac1 ~]$ sqlplus / as sysdba

SQL>

(4) 使用RMAN恢復SPFILE到ASM磁盤組DATADG

[oracle@rac1 ~]$ rman target /

Recovery Manager: Release 11.2.0.3.0 - Production on Sat Jul 6 13:59:26 2013

channel ORA_DISK_1: SPFILE restore from AUTOBACKUP complete
Finished restore at 06-JUL-13

(5) 使用恢復後spfile啟動數據庫，並修改control_files，db_recovery_file_dest，log_archive_dest等存在舊路徑的參數值。

[oracle@rac1 ~]$ vi $ORACLE_HOME/dbs/initcsdb1.ora

SPFILE=‘+DATADG/csdb/spfilecsdb.ora‘

(6) 查看數據庫的DBID

[oracle@rac1 ~]$ strings /u01/app/oracle/backup/CSDB_819991120_5.bk | grep MAXVALUE,

返回的值類似下面的例子，其中那一竄數字即為DBID。
...
MAXVALUE, MAXVALUE!
3042905279, MAXVALUE,
3042905279, MAXVALUE,
...

(7) 恢復控制文件到新的ASM磁盤組DATADG

[oracle@rac1 ~]$ rman target /
