Is the maximum volume size that can be allocated via cinder dependent on the backend driver's limitations only? Or does cinder add additional limitations?

I'm talking about a single volume here, not a volume group or quota or anything. A single volume that will be attached to an instance as a block device.

For example, LVM max logical volume size is, afaik, 256TB. Does that mean that using LVM as the backend I can create volumes of that size? Or does cinder have another built-in limit?

Thanks!

That should be correct that the backend storage provider is where the limitations come from. Cinder is concerned with quotas over and above the infrastructure capabilities.
