First, your statement and subject is hyperbolic and combative. In general it's best not to begin any approach for help with an uneducated attack on a community.
GFS (Global File System) is an entirely different project but I'm going to assume you're in the right place and actually asking about GlusterFS.
You haven't described your use case so I'll make an assumption that your intent is to sync files from your office to your home. I'll further guess that you're replicating one brick at home and the other at the office.
Yes, this is generally an unusable use case for to latency and connectivity reasons. Your 2Gb transfer was very likely a self heal due to a connectivity problem from one of your clients. When your home client performed a lookup() of the files, it caught the discrepancy and fixed it. The latency is multiplied due to the very nature of clustering and your latent connection.
For a more useful answer, I'd suggest describing your needs and asking for help. There is tons of experienced storage professionals here that are happy to share their knowledge and advice.
