Yes, in 2.6.28 (and .27) one can create a volume > 16TB if the clustersize is made > 4KB. Multiplying the clustersize with 4G gets you the volume size limit.
The reason mkfs is failing is because tools 1.4.1 is a bit dated. The mkfs in the git repo has the changes needed. Yes, we need to release an updated version of the tools. ;) BTW, we intend to allow clustersize 4KB to break the 16T volume size limit too. Just a matter of time.
