I am trying to expand the C drive on a recently P2V server. I have added 30 GB via VM settings, and the additional space shows up on Disk Mgt marked Unallocated. The problem is that Extpart cant see it and won't expand the volume.
Any similar experiences ?

Thanks

Yes, plenty of times. You could have expanded when you did the original P2V!

1. Restart the VM. Try again.

As mentioned you could have done this via P2V VMware converter stage. Dells Extpart utility is a nice alternative for pre-2008 OS.

Please reboot the machine and run Extpart again, choose to run as Administrator.

Thank you for the quick reply. I restarted the server again, and run extpart in safe mode - still no joy. Using GParted I can see that the additional storage is automatically being added to the partition that is marked as sda2. Not sure why this is happeing.

The smaller one, 20gb  ;) . This is the view from Dsk Mgt in Win.

It's because you have a dynamic disk. Partition modifications with dynamic disks is not supported by many third party partition managers.

So the partition you need to increase is the first one?

C: Operating....

Even if this was not a dynamic disk, you would need to move all the partitions down the disk, one by one, and then grow the C: partition into the empty space.

I would re-visit, and Re-P2V if possible, move the partitions on their own virtual disks, it makes partition modifications in the future much easier.

Thanks. Unfortunately P2V is no longer viable. Would V2V be of any use ?
