Hi, newbie question. I need to build this:

• /shared folder ~500GB of files, ~1MB each one.
• Two boxes (server1 and server2) connected by a 1Gbs LAN
• Every box needs to get r/w access to the files, so their are both clients
• I want that the files replicated on both boxes, every time a file is written in one server the same file should be present in the other one.

My questions regarding GlusterFS:

• It'll duplicate the files on the same box?. For example the files are on /shared and the mount in /mnt/shared. It'll take 1GB space on every server?
• Instead, should I use the filesystem directly, locally writing on /shared? Does the replication work in this way without mountin a client?

Also, if anyone know any other way to acomplish this setup I'll be very grateful. Thanks in advance.
