Adding space to a Citrix Provisioning Services Vdisk without reverse imaging.

In the course of patching and modification a Citrix Provisioning Services disk image can sometimes exceed it's original storage capacity. Like a normal virtual machine, a PVS image can be extended to increase its useful life. As this is executed against an umnounted, unused PVS image the risk is minimal. Failback is to create a clean image from the current gold image.

Preparation 

Prior to attempting to extend a Vdisk ensure that it is not locked, in use or mounted in PVS (the lock icon indicates whether it is locked or not and if it is in use the Connections will be greater than 0).

Execution 

Open an command prompt and issue the Diskpart Command (on some systems escalation is required).:



 Select the Vdisk to modify and attach it to Diskpart:



Increase the maximum size of the VDisk (Size is in Megabytes):



Attach the vdisk and determine the correct volume to extend:



Select the volume to extend and execute the extend command:



Review your results:



Clean up and exit:
