The parent virtual disk has been modified since the child was created

简介:

Problem:

wKioL1dXgvijpSoAAAA0FTIe0r8200.png


具体的消息是:

Failed to start the virtual machine.

Module DiskEarly power on failed.

Cannot open the disk '/vmfs/volumes/54627907-c2477c60-ec2b-0024e8573a7f/WebServer_Version2/WebServer_Version 2-000008.vmdk' or one of the snapshot disks it depends on.

The parent virtual disk hasbeen modified since the child was created. The content ID of the parent virtual disk doesnot match the corresponding parent content ID in the child

 解决方法和思路:

--------------------------------------

1. 先开启任意一个机器上的SSH服务

2. 然后用ssh 登录到这个ESXI计算机上

3. 运行下面的命令

Cat WebServer_Version\ 2.vmdk

------------------------------------------------------------

# Disk DescriptorFile

version=1

encoding="UTF-8"

CID=60025a0a

parentCID=ffffffff

isNativeSnapshot="no"

createType="vmfs"

# Extent description

RW 167772160 VMFS "WebServer_Version 2-flat.vmdk"

# The Disk Data Base

#DDB

ddb.adapterType = "lsilogic"

ddb.deletable = "true"

ddb.geometry.cylinders = "10443"

ddb.geometry.heads = "255"

ddb.geometry.sectors = "63"

ddb.longContentID ="4335f3cc11a7c8500cdb139a60025a0a"

ddb.uuid = "60 00 C2 99 f5 15 36 81-06 e3 f8 b6 66 dc30 de"

ddb.virtualHWVersion = "8"

 

/vmfs/volumes/54627907-c2477c60-ec2b-0024e8573a7f/WebServer_Version2 cat WebServer_Version\ 2-000008.vmdk

# Disk DescriptorFile

version=1

encoding="UTF-8"

CID=7e05ba5d

parentCID=75d5382b


createType="vmfsSparse"

parentFileNameHint="WebServer_Version 2.vmdk"

# Extent description

RW 167772160 VMFSSPARSE "WebServer_Version2-000008-delta.vmdk"

 # The Disk Data Base

#DDB

 ddb.longContentID = "901af6c76efda040f8d76a817e05ba5d"


4. 在检查的vmdk中,我们可以看到parentCID是和上面的CID不一样的。

5. 然后把备份这个文件夹通过下载的方法

6. 编辑WebServer_Version\ 2-000008.vmdk中的ParentCID为60025a0a


P.S.

在ESXI中所有的VM都存放在/vmfs/volumes下面,后面的一串ID是和我们建立存储的friendly的一个硬连接
