FAILED: An error occurred during the conversion: Cannot format volume

Searching I couldn't find anything related to "Cannot format volume"

Tried converting Windows 2008R2 server from one vSphere 5.1 server to a new vSphere 6.0 using vCenter Converter Standalone 6.

The source VM was fully powered off.

4 partitions on the server, 3 were successful but the last failed almost immediately.

One partition was increased from 100GB to 200GB, that was successful.

Second and third partition was 220GB and left alone, successful

The fourth partition failed we were trying to increase the size from 500GB to 2TB.

You're trying make the P2V and resize the disk at the same time ? If yes, why not just make the P2V first to move the virtual machine to the new host and then resize the disk ?

Not 100% sure, but I think the problem is related to the 2TB disk, since vSphere 5.1 does not support vmdk with 2TB size (maximum supported is 2TB minus 512 bytes).

What Windows version is Converter running on? It needs to recognize the NTFS version of the source machine.

Also ReFS cannot be resized but shouldn't be available on Win 2008R2.

Correction, ReFS can be resized with Converter 6.0.

OTOH if the datastore is VMFS-3 formatted, it wouldn't support 2TB+ vmdks, even if accessed by ESXi 6.0.

That's what I thought, the 2TB was not supported.

I converted a test system over, increasing to 1TB.

After a successful conversion, I edited the VM settings and increased the hard drive to 2TB.

Booted into GParted ISO and modified the partition to 2TB.

Rebooted Windows, chkdsk performed a scan.

Rebooted 2nd time back into Windows.

Verified I have a 2TB drive.

In essence, I didn't even have to increase to 1TB during the conversion, I could have left it as it was and just modified after like I did.

Thank you for your comments and direction.
