Can gluster be used as a WAN-based distributed filesystem? I've got four servers spread around the country to provide geographic redundancy and am looking for a good system that I can maintain continuity between the servers. Replication, etc. Currently using rsync which is just terrible and has a high overhead as I've got large directories that need continuous updates. ---------------- Thank you, Chris Bidwell, RHCT Red Hat Linux Administrator

Afaik Gluster is designed for high-bandwidth / low-latency environments, such as LANs and storage networks - not for WANs. People have tried though, of course ; search the archives for more information. -- Daniel Maher <dma+gluster AT witbe DOT net>

Bandwidth isn't so much of a problem as latency. Gluster doesn't have an async mode, so you have to wait for your operations to complete on all nodes -- that can take a while. Our current setup backs a couple Samba shares, users seem happy.
