So in my case where i have one directory with existing data and another that is empty, should i set the trusted version to 1 on the pre existing data and 3 on the empty directory? Or am I totally missing what this does? I agree starting with a clean slate is much easier/cleaner. But when you have 100 gigs of data consisting of tons of tiny files (web or mail data) it would be ideal to me anyway to be able to use the existing directory and somehow tell glusterfs that this is good data and that the empty directory is out of date. I guess this is more just a case of needing some documentation on the proper steps and order of executing this conversion?
