在安装Oracle Clusterware过程中使用ASM管理VMware共享磁盘时遇到问题。当创建独立持久虚拟磁盘未选择完全分配空间选项时，第二节点启动ASM实例失败，提示共享磁盘损坏。通过修改vmx文件并指定使用plainDisk类型及设置相关参数最终解决了问题。

I was installing Clusterware using ASM on VMware shared disks. When I created the independent persistent virtual disks, I left the “allocate all disk space now” option unselected. Oracleasm was happy on both RAC nodes. The Oracle installer was happy when it created +ASM1 on the first RAC node. But when the ASM instance started on node 2 it did not like the “virtually provisioned” disk. The +ASM2 instance was not open and was complaining about one of the shared disks being corrupt at a certain byte. When I checked the virtual disk files, I saw that Oracle was trying to read past the end of the file. I started all over with new fully allocated shared disk and that fixed the problem. Everything is up and running now.

该方法我尝试后依旧未能解决，最终，通过修改vmx文件，添加如下：在每一个scsi1:x的下面添加scsi1:x.deviceType = "plainDisk" scsi1:1.present = "TRUE" scsi1:1.mode = "independent-persistent" scsi1:1.filename = "K:\VMDisk\Sharedisk\ocr.vmdk" scsi1:1.deviceType = "plainDisk" scsi1:2.present = "TRUE" scsi1:2.mode = "independent-persistent" scsi1:2.filename = "K:\VMDisk\Sharedisk\votingdisk.vmdk" scsi1:2.deviceType = "plainDisk" scsi1:3.present = "TRUE" scsi1:3.mode = "independent-persistent" scsi1:3.filename = "K:\VMDisk\Sharedisk\data.vmdk" scsi1:3.deviceType = "plainDisk" scsi1:4.present = "TRUE" scsi1:4.mode = "independent-persistent" scsi1:4.filename = "K:\VMDisk\Sharedisk\backup.vmdk" scsi1:4.deviceType = "plainDisk" scsi1:5.present = "TRUE" scsi1:5.mode = "independent-persistent" scsi1:5.filename = "K:\VMDisk\Sharedisk\ocr2.vmdk" scsi1:5.deviceType = "plainDisk" 并添加： disk.locking = "false" diskLib.dataCacheMaxSize = "0" diskLib.dataCacheMaxReadAheadSize = "0" diskLib.DataCacheMinReadAheadSize = "0" diskLib.dataCachePageSize = "4096" diskLib.maxUnsyncedWrites = "0" disk.EnableUUID = "TRUE" 终于第二节点跑过了root.sh
