在11GR2的环境下，将rac的OCR , Vote File , ASM SPILE迁移到到新的磁盘组。
现在的磁盘状态：
[root@rac1 ~]# crsctl query css votedisk ## STATE File Universal Id File Name Disk group -- ----- ----------------- --------- --------- 1. ONLINE 0c9ec99614ed4fe4bfdba4cb520dd00e (/dev/raw/raw1) [OCRVOTING] Located 1 voting disk(s). [root@rac1 ~]# ocrcheck Status of Oracle Cluster Registry is as follows : Version : 3 Total space (kbytes) : 262120 Used space (kbytes) : 2544 Available space (kbytes) : 259576 ID : 827782161 Device/File Name : +OCRVOTING Device/File integrity check succeeded Device/File not configured Device/File not configured Device/File not configured Device/File not configured Cluster registry integrity check succeeded Logical corruption check succeeded SQL> set line 300 SQL> col failgroup for a40 SQL> col name for a30 SQL> select DISK_NUMBER,REDUNDANCY,name,FAILGROUP,VOTING_FILE from v$asm_disk; DISK_NUMBER REDUNDANCY NAME FAILGROUP VOT ----------- ---------- --------------- ---------------- --- 1 UNKNOWN OCRVOTING_0001 OCRVOTING_0001 N 0 UNKNOWN RAC_DATA_0000 RAC_DATA_0000 N 0 UNKNOWN OCRVOTING_0000 OCRVOTING_0000 Y 2 UNKNOWN OCRVOTING_0002 OCRVOTING_0002 N SQL> select name,total_mb,free_mb,usable_file_mb from v$asm_diskgroup;

可以看到，ocr磁盘组冗余度为external，而且是使用的裸设备，下面将ocr磁盘组移动到冗余度为normal类型的磁盘组里。
首先分配三块盘，因为是自己的测试环境，不需要太大，每块盘1G就可以。
创建共享磁盘
Cmd命令： vmware-vdiskmanager.exe -c -s 1000Mb -a lsilogic -t 2 F:\RAC\sharedisk\ocrdisk01.vmdk vmware-vdiskmanager.exe -c -s 1000Mb -a lsilogic -t 2 F:\RAC\sharedisk\ocrdisk02.vmdk vmware-vdiskmanager.exe -c -s 1000Mb -a lsilogic -t 2 F:\RAC\sharedisk\ocrdisk03.vmdk
|
两个虚拟机配置文件追加如下内容
scsi1:5.present = "TRUE" scsi1:5.mode = "independent-persistent" scsi1:5.filename = "F:\RAC\sharedisk\ocrdisk01.vmdk" scsi1:5.deviceType = "plainDisk"
scsi1:6.present = "TRUE" scsi1:6.mode = "independent-persistent" scsi1:6.filename = "F:\RAC\sharedisk\ocrdisk02.vmdk" scsi1:6.deviceType = "plainDisk"
scsi1:8.present = "TRUE" scsi1:8.mode = "independent-persistent" scsi1:8.filename = "F:\RAC\sharedisk\ocrdisk03.vmdk" scsi1:8.deviceType = "plainDisk"
|
注意这里不能用7,7是系统保留的，不可用。
查看新增盘:
[root@rac1 ~]# fdisk -l|grep sd Disk /dev/sda: 19.3 GB, 19327352832 bytes /dev/sda1 * 1 64 512000 83 Linux /dev/sda2 64 1306 9972736 8e Linux LVM /dev/sda3 1306 1566 2093135 8e Linux LVM /dev/sda4 1567 2349 6289447+ 8e Linux LVM Disk /dev/sdb: 1048 MB, 1048576000 bytes /dev/sdb1 1 1000 1023984 83 Linux Disk /dev/sdc: 1048 MB, 1048576000 bytes /dev/sdc1 1 1000 1023984 83 Linux Disk /dev/sdd: 10.5 GB, 10485760000 bytes /dev/sdd1 1 1274 10233373+ 83 Linux Disk /dev/sde: 1048 MB, 1048576000 bytes /dev/sde1 1 1000 1023984 83 Linux Disk /dev/sdf: 1048 MB, 1048576000 bytes Disk /dev/sdg: 1048 MB, 1048576000 bytes Disk /dev/sdh: 1048 MB, 1048576000 bytes
|
sdf,sdg,sdh是我们新分配的三块盘。
编辑60-raw.rules文件：
[root@rac1 rules.d]# more 60-raw.rules # Enter raw device bindings here. # # An example would be: # ACTION=="add", KERNEL=="sda", RUN+="/bin/raw /dev/raw/raw1 %N" # to bind /dev/raw/raw1 to /dev/sda, or # ACTION=="add", ENV{MAJOR}=="8", ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m" # to bind /dev/raw/raw2 to the device with major 8, minor 1. ACTION=="add", KERNEL=="sdb1",RUN+="/bin/raw /dev/raw/raw1 %N" ACTION=="add", KERNEL=="sdc1",RUN+="/bin/raw /dev/raw/raw2 %N" ACTION=="add", KERNEL=="sdd1",RUN+="/bin/raw /dev/raw/raw3 %N" ACTION=="add", KERNEL=="sde1",RUN+="/bin/raw /dev/raw/raw4 %N" ACTION=="add", KERNEL=="sdf",RUN+="/bin/raw /dev/raw/raw5 %N" ACTION=="add", KERNEL=="sdg",RUN+="/bin/raw /dev/raw/raw6 %N" ACTION=="add", KERNEL=="sdh",RUN+="/bin/raw /dev/raw/raw7 %N" ACTION=="add",KERNEL=="raw[1-7]", OWNER="grid", GROUP="oinstall", MODE="660" |
重启udev并检查
[root@rac1 ~]# start_udev Starting udev: [ OK ] [grid@rac1 ~]$ cd /dev/raw [grid@rac1 raw]$ ll total 0 crw-rw---- 1 grid oinstall 162, 1 Jun 10 23:44 raw1 crw-rw---- 1 grid oinstall 162, 2 Jun 10 23:43 raw2 crw-rw---- 1 grid oinstall 162, 3 Jun 10 23:43 raw3 crw-rw---- 1 grid oinstall 162, 4 Jun 10 23:43 raw4 crw-rw---- 1 grid oinstall 162, 5 Jun 10 23:43 raw5 crw-rw---- 1 grid oinstall 162, 6 Jun 10 23:43 raw6 crw-rw---- 1 grid oinstall 162, 7 Jun 10 23:43 raw7 crw-rw---- 1 root disk 162, 0 Jun 10 23:43 rawctl
|
图形界面创建OCRDG,这部分比较简单省略:
[grid@rac1 raw]$ asmca
图形界面创建成功之后，点击了mount all，下面验证一下新创建的磁盘组是否已经mount：
[grid@rac1 raw]$ sqlplus / as sysasm SQL> col name for a20 SQL> select NAME,GROUP_NUMBER,STATE,type,TOTAL_MB,FREE_MB,usable_file_mb,VOTING_FILES from v$asm_diskgroup;
NAME GROUP_NUMBER STATE TYPE TOTAL_MB FREE_MB USABLE_FILE_MB VOT ----------- ------------ -------- ------- ---------- ---------- -------------- --- OCRVOTING 1 MOUNTED EXTERN 2997 2597 2597 N RAC_DATA 2 MOUNTED EXTERN 9993 8077 8077 N OCRDG 3 MOUNTED NORMAL 3000 2715 1310 N 可以看到新创建的ocrdg磁盘组的状态已经mount，类型是normal。
磁盘状态： SQL> select GROUP_NUMBER,DISK_NUMBER,MOUNT_STATUS,NAME,VOTING_FILE from v$asm_disk;
GROUP_NUMBER DISK_NUMBER MOUNT_STATUS NAME VOT ------------ ----------- --------------------- -------------------- --- 1 2 CACHED OCRVOTING_0002 N 1 1 CACHED OCRVOTING_0001 N 1 0 CACHED OCRVOTING_0000 Y 2 0 CACHED RAC_DATA_0000 N 3 2 CACHED OCRDG_0002 N 3 1 CACHED OCRDG_0001 N 3 0 CACHED OCRDG_0000 N

也可以用下面命令验证：
[grid@rac1 raw]$ asmcmd lsdg
asm pfile文件位置：
[grid@rac1 ~]$ asmcmd spget +OCRVOTING/rac-cluster/asmparameterfile/registry.253.952478315 |
备份之前的OCR,OLR，单节点:
[root@rac1 rules.d]# ocrconfig -manualbackup [root@rac1 rules.d]# ocrconfig -local -manualbackup |
将新磁盘组增加到OCR，root用户：
[root@rac1 rules.d]# /tpsys/app/11.2.0/grid/bin/ocrconfig -add +OCRDG
检查crs日志，命令行确认：
此时的crs日志： 2018-06-12 06:19:30.517: [ OCRRAW][2996766464]propriowv_bootbuf: Vote information on disk 1 [+OCRDG] is adjusted from [0/0] to [1/2] 2018-06-12 06:19:30.546: [ OCRRAW][2996766464]propriowv_bootbuf: Vote information on disk 0 [+OCRVOTING] is adjusted from [2/2] to [1/2]
[root@rac1 rules.d]# ocrcheck Status of Oracle Cluster Registry is as follows : Version : 3 Total space (kbytes) : 262120 Used space (kbytes) : 2596 Available space (kbytes) : 259524 ID : 827782161 Device/File Name : +OCRVOTING Device/File integrity check succeeded Device/File Name : +OCRDG Device/File integrity check succeeded Device/File not configured Device/File not configured Device/File not configured Cluster registry integrity check succeeded Logical corruption check succeeded
|
将旧的磁盘组踢出：
[root@rac1 rules.d]# /tpsys/app/11.2.0/grid/bin/ocrconfig -delete +OCRVOTING
检查crs日志，命令行确认：
此时的crs日志： 2018-06-12 06:28:07.526: [ OCRRAW][2986276608]propriowv_bootbuf: Vote information on disk 1 [] is adjusted from [1/2] to [2/2] 2018-06-12 06:28:07.647: [ OCRASM][2986276608]proprasmo: ASM cache size is [5MB] 2018-06-12 06:28:07.647: [ OCRASM][2986276608]proprasmo: ASM cache [5MB] enabled for disk group [OCRDG]. 2018-06-12 06:28:07.693: [ OCRRAW][2986276608]proprioo: for disk 0 (+OCRDG), id match (1), total id sets, (2) need recover (0), my votes (2), total votes (2), commit_lsn (68), lsn (68) [root@rac1 rules.d]# ocrcheck Status of Oracle Cluster Registry is as follows : Version : 3 Total space (kbytes) : 262120 Used space (kbytes) : 2596 Available space (kbytes) : 259524 ID : 827782161 Device/File Name : +OCRDG Device/File integrity check succeeded Device/File not configured Device/File not configured Device/File not configured Device/File not configured Cluster registry integrity check succeeded Logical corruption check succeeded |
替换vote disk：
[root@rac1 rules.d]# crsctl query css votedisk ## STATE File Universal Id File Name Disk group -- ----- ----------------- --------- --------- 1. ONLINE 0c9ec99614ed4fe4bfdba4cb520dd00e (/dev/raw/raw1) [OCRVOTING] Located 1 voting disk(s).
[root@rac1 rules.d]# /tpsys/app/11.2.0/grid/bin/crsctl replace votedisk +OCRDG
Successful addition of voting disk 0a80756b9eb44f9abfae577e0e8ed2dd. Successful addition of voting disk 000808a364544f11bf48969149e2bf2a. Successful addition of voting disk 8714d5dd04634f70bf3bbd8ae1a467ac. Successful deletion of voting disk 0c9ec99614ed4fe4bfdba4cb520dd00e. Successfully replaced voting disk group with +OCRDG. CRS-4266: Voting file(s) successfully replaced
验证，root用户： [root@rac1 rules.d]# crsctl query css votedisk ## STATE File Universal Id File Name Disk group -- ----- ----------------- --------- --------- 1. ONLINE 0a80756b9eb44f9abfae577e0e8ed2dd (/dev/raw/raw5) [OCRDG] 2. ONLINE 000808a364544f11bf48969149e2bf2a (/dev/raw/raw6) [OCRDG] 3. ONLINE 8714d5dd04634f70bf3bbd8ae1a467ac (/dev/raw/raw7) [OCRDG] Located 3 voting disk(s).

创建asm pfile到新的磁盘组：
[grid@rac1 ~]$ sqlplus / as sysasm SQL> create pfile='/tmp/asmpfile.ora' from spfile; File created.
SQL> create spfile='+OCRDG' from pfile='/tmp/asmpfile.ora'; File created.
[grid@rac1 ~]$ asmcmd spget +OCRDG/rac-cluster/asmparameterfile/registry.253.978589927
|
使用新的pfile文件重启集群：
crsctl stop crs
crsctl start crs
[grid@rac2 ~]$ crsctl stat res -t
