Have a simple question for someone.

Looking at migrating a client to XCP. Currently they have a data disk that is exactly 2TB in VMware.

My question is the limitation anything OVER 2TB, or is it 2TB AND above?
I'd prefer not to use the VMware converter tool to shrink the disk to 1.99TB if I don't have to.

VHD format has a strict limit of roughly 2TB (around 2040 GB), so if your client’s VM disks are larger than this then you’re going to have trouble with VHD format. However QCOW2 support is almost here (production ready) about to reach RC2 state, once this reaches stable you’ll be able to safely reach a max of around 16TB. That is if your using ext4 based SR, other Filesystems have different limits. If using a networked file sharing protocol service then, the limit of the host server’s filesystem applies.
