XenServer VM low on space

I have a couple of VM's that were P2V'd about a year ago and when they were created (not by me) the drive size was matched to what the physical box was, in this case 50GB. Normally I could shut the VM down, change the disk size in XenCenter, fire up the VM and extend the disk. Not in this case.

The disk is a dynamic disk (again not my doing) and I get the following error when trying to extend the drive.

I tried gparted as well but the operation failed with that tool as well.

Is there anything that can be done at this point? I was thinking of making that VM a template and then creating a new VM from that and give it a larger drive during the creation process. Would that work? I know I'd have to reactivate Windows but that's not a huge deal.

Thoughts?

You need to mount the vDisk on another VM to extend under 2003.

can you elaborate a bit? Are you saying I can shut this VM down, attach it to another VM, boot that up and extend to my hearts contention? Then detach, reattach to original VM and start'er up and be good to go?
 
Pretty much:

1.Shut VM-A down.
2.Attach vDisk from VM-A to VM-B
3.Extend disk
4.Detach disk from VM-B
5.Power on VM-A

2003 does not allow extending a system disk, by mounting it onto another system as a non-system disk the system will allow the extension.
 
I didn't realize it was that simple. Thanks for the suggestion, I will give it a whirl tonight.

hm, that didn't work for me. The disk that needs extending shows up in disk management as foreign and that is has errors.

any suggestions?
 
What error did gparted give? I've used it in the past to do this.
 
I wanted to follow up on this in case anyone else ran into this. I didn't get to try gparted again to get the error but I ended up spending $159 on Easeus Partition Master Server edition and installed in on the VM's that had these issues. I was able to both convert from a dynamic disk to a basic disk and also extend the system volume as I needed.

money well spent IMO. Thanks for the replies, glad this is behind me now.
