Citrix PVS: Version disk file timestamp is inconsistent with that in manifest file

Version disk file timestamp is inconsistent with that in manifest file cannot add vdisk

Scenario

• You have two Citrix PVS Farms, let’s say Farm A and Farm B. Each farm has a single site. 
• Vdisk updates take place in Farm A then get copied across to Farm B
• You have created new vdisk version(s) in Farm A, now you need to add those in Farm B but you get an error: Version disk file timestamp is inconsistent with that in manifest file for cannot add vdisk

Solution

• Copy all VHDX and PVP files from Farm A Store to Farm B Store. 
• For both farms, right click on the vdisk and “Export vdisk” making sure you “Start at” the latest version. This should get you a XML file for each farm.
• Use Notepad++ to compare the two files. This can be done by adding the “Compare” plugin. 
• When comparing, a timestamp difference between the two files for certain vhdx might be found. The mismatching line would look something like this:

From Farm A:

<lastWriteTime>2019-08-16T11:04:47</lastWriteTime>

From Farm B:

<lastWriteTime>2019-08-16T13:24:32</lastWriteTime>

• Change the timestamp in XML A to match XML B and copy it across to Farm B Store.
• Retry to add vdisk versions. It should work without errors.

Problem Cause:

When base VHDX file was copied from Farm A to B earlier, the timestamp of the file gets changed. Subsequent XML exports coming from Farm A would no longer have a matching timestamp which triggers the error.
