Gluster users - Mar 2015 - Setting up geo-replication with existing data on both ends

I'm looking to set up cascading geo-rep across 3 datacentres and I have
nearly 2TB to start with.  To avoid incurring insane bandwidth overage fees
transfering all that data from one DC to the next to the next, I'd like to
place the data directly on each server from an external HDD to start and
then enable geo-replication to keep the data in sync.  Will this work?  Is
there process for setting up geo-replication between volumes that already
contain data?

Thanks,
Peter
