Aren't you supposed to use gpt(8) to define partitions larger than 2 TB? > Is newfs supposed to be able to work?

Then the question is whether newfs reads gpt-partitioned disks? From newfs(8): Before running newfs the disk must be labeled using bsdlabel(8). How did you create such a huge partition? Your question is quite interesting, I'm at a storage-solution which supports LUN's larger than 2.2 TB. regards Claus
