Hi gurus,
we currently encounter problems with one of our Windows 2008 64bit machines (not R2!).
The server is backuped with VDR 1.2.0.1131. At the beginning the snapshot is taken - everthings fine so far. But after the snap completed and the backup is running, disk D inside the guest system becomes readonly!
This RO flag isn't remoed anymore, even after the backup completed and the server is not usable anymore. The following errors are displayed in the logs of the windows server:
System Log:
Application Log:
Does anybody has seen this error before and can assist to fix this?
Thanks and best regards
Marco

Basiclly you need to disable the Virtual Machine Application Consistent Quiescing to solve your problem.
1 Start the vSphere Client, and log in to a vCenter Server.
2 Select Virtual Machines and Templates and click the Virtual Machines tab.
3 Right‐click the Windows 2008 virtual machine for which you are enabling the disk UUID attribute, and select Power > Power Off. The virtual machine
powers off.
4 Right‐click the virtual machine, and click Edit Settings.
5Click the Options tab, and select the General entry in the settings column.
6Click Configuration Parameters… The Configuration Paramters window appears.
7Click Add Row.
8 In the Name column, enter disk.EnableUUID.
9In the Value column, enter FALSE.
10 Click OK and click Save.
11 Power on the virtual machine.

Hi,
thanks a lot for your reply.
Because this machine can't be powered off during the day, we'll check this flag tonight. I will post the result later on...

Hi,
unfortunately this doesn't resolve my issue.
The flag you mentioned is set, so the VM was created with vSphere 4.1 supporting application quiescing:
So this is not the problem, isn't it?
For applicationconsistent quiescing to be available, three conditions must be met:

Our affected VM uses drive D as dynamic disk. Perhaps this is the root cause of the problem?
Please advise...
Thanks and best regards

Sorry, my fault!
You told me to disable (FALSE) this flag. Whyever I read to enable (TRUE) it, as it is already set to true...
We'll try to disable the flag and see what happens....
Best regards
