配置共享存储
这个是重点，也是最容易出错的地方，这次是小麦苗第二次虚拟机上安装RAC环境，有的内容不再详述。
添加共享磁盘
第一步：创建共享磁盘
该步骤可以用cmd命令也可以用图形界面，本文采用命令行进行添加。
在cmd 中进入 WMware Workstation安装目录，执行命令创建磁盘：
1 2 3 4 5 6 7 | C: cd C:\Program Files (x86)\VMware\VMware Workstation vmware-vdiskmanager.exe -c -s 6g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\ocr_vote.vmdk" vmware-vdiskmanager.exe -c -s 10g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\data.vmdk" vmware-vdiskmanager.exe -c -s 10g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\fra.vmdk" |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | D:\Users\xiaomaimiao>C: C:\>cd C:\Program Files (x86)\VMware\VMware Workstation C:\Program Files (x86)\VMware\VMware Workstation>vmware-vdiskmanager.exe -c -s 6g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\ocr_vote.vmdk" Creating disk 'E:\My Virtual Machines\rac12cR1\sharedisk\ocr_vote.vmdk' Create: 100% done. Virtual disk creation successful. C:\Program Files (x86)\VMware\VMware Workstation>vmware-vdiskmanager.exe -c -s 10g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\data.vmdk" Creating disk 'E:\My Virtual Machines\rac12cR1\sharedisk\data.vmdk' Create: 100% done. Virtual disk creation successful. C:\Program Files (x86)\VMware\VMware Workstation>vmware-vdiskmanager.exe -c -s 10g -a lsilogic -t 2 "E:\My Virtual Machines\rac12cR1\sharedisk\fra.vmdk" Creating disk 'E:\My Virtual Machines\rac12cR1\sharedisk\fra.vmdk' Create: 100% done. Virtual disk creation successful. |
注意：12c R1的OCR磁盘组最少需要5501MB的空间。
1 2 3 4 | [INS-30515] Insufficient space available in the selected disks. Cause - Insufficient space available in the selected Disks. At least, 5,501 MB of free space is required. Action - Choose additional disks such that the total size should be at least 5,501 MB. |
第二步：修改配置文件
关闭两台虚拟机，用记事本打开 虚拟机名字.vmx，即打开配置文件，2个节点都需要修改。
添加以下内容，其中，scsix:y 表示第x个总线上的第y个设备:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | #shared disks configure disk.EnableUUID="TRUE" disk.locking = "FALSE" scsi1.shared = "TRUE" diskLib.dataCacheMaxSize = "0" diskLib.dataCacheMaxReadAheadSize = "0" diskLib.dataCacheMinReadAheadSize = "0" diskLib.dataCachePageSize= "4096" diskLib.maxUnsyncedWrites = "0" scsi1.present = "TRUE" scsi1.virtualDev = "lsilogic" scsil.sharedBus = "VIRTUAL" scsi1:0.present = "TRUE" scsi1:0.mode = "independent-persistent" scsi1:0.fileName = "..\sharedisk\ocr_vote.vmdk" scsi1:0.deviceType = "disk" scsi1:0.redo = "" scsi1:1.present = "TRUE" scsi1:1.mode = "independent-persistent" scsi1:1.fileName = "..\sharedisk\data.vmdk" scsi1:1.deviceType = "disk" scsi1:1.redo = "" scsi1:2.present = "TRUE" scsi1:2.mode = "independent-persistent" scsi1:2.fileName = "..\sharedisk\fra.vmdk" scsi1:2.deviceType = "disk" scsi1:2.redo = "" |
如果报有的参数不存在的错误，那么请将虚拟机的兼容性设置到Workstation 9.0
第三步：重新打开VMware Workstation
关闭 VMware Workstation 软件重新打开，此时看到共享磁盘正确加载则配置正确，这里尤其注意第二个节点，2个节点的硬盘配置和网络适配器的配置应该是一样的，若不一样请检查配置。
然后开启2台虚拟机。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | [root@raclhr-12cR1-N1 ~]# fdisk -l | grep /dev/sd Disk /dev/sda: 21.5 GB, 21474836480 bytes /dev/sda1 * 1 26 204800 83 Linux /dev/sda2 26 1332 10485760 8e Linux LVM /dev/sda3 1332 2611 10279936 8e Linux LVM Disk /dev/sdb: 107.4 GB, 107374182400 bytes /dev/sdb1 1 1306 10485760 8e Linux LVM /dev/sdb2 1306 2611 10485760 8e Linux LVM /dev/sdb3 2611 3917 10485760 8e Linux LVM /dev/sdb4 3917 13055 73399296 5 Extended /dev/sdb5 3917 5222 10485760 8e Linux LVM /dev/sdb6 5223 6528 10485760 8e Linux LVM /dev/sdb7 6528 7834 10485760 8e Linux LVM /dev/sdb8 7834 9139 10485760 8e Linux LVM /dev/sdb9 9139 10445 10485760 8e Linux LVM /dev/sdb10 10445 11750 10485760 8e Linux LVM /dev/sdb11 11750 13055 10477568 8e Linux LVM Disk /dev/sdc: 6442 MB, 6442450944 bytes Disk /dev/sdd: 10.7 GB, 10737418240 bytes Disk /dev/sde: 10.7 GB, 10737418240 bytes [root@raclhr-12cR1-N1 ~]# fdisk -l | grep "Disk /dev/sd" Disk /dev/sda: 21.5 GB, 21474836480 bytes Disk /dev/sdb: 107.4 GB, 107374182400 bytes Disk /dev/sdc: 6442 MB, 6442450944 bytes Disk /dev/sdd: 10.7 GB, 10737418240 bytes Disk /dev/sde: 10.7 GB, 10737418240 bytes [root@raclhr-12cR1-N1 ~]# |
设置共享磁盘
配置udev绑定的scsi_id
注意以下两点：
- 首先切换到root用户下
2个节点上获取的uuid应该是一样的，不一样的话说明之前的配置有问题
