As you play with the > system, you will see more and more possibilities :-). Hum! Interesting. Thanks for the tip. I'm still curious about why the previous configuration didn't work. Can you tell me if using the replication translator over distributed volumes is supported? > So what purpose do you intend to put the system to ? Well, we have a driving project, an application that needs scalable storage, and we'd like to use the chosen system for other existing projects that are now running over NFS exported filesystems (hence the need for posix) and for future projects with largish/scalable storage needs. We plan on trying it for storing our VM images too, which I've seen that some people do. So, basically, we need a scalable, redundant and flexible storage system, hopefully also easy to operate and configure when adding new nodes and disks. GlusterFS seemed perfect, with its layered approach and shared-nothing design :) Thank you all very much for your work! regards, z?
