Problem: I want to replicate volumes larger than 16TB. Is there any possibility to avoid this limitation?

Solution:

There is a patch but there is a risk that the bigger the volume is the harder it may be to repair file system in case of corruption etc.
Also all our tests and certifications are done for volumes <16TB so we can't guarantee that your system will be stable after applying it.

However, if you wish to use this Small Update for V7 here is it's number: 70018
