Right now I'm trying Glusterfs which seems workable but I'm not sure how it'll handle it if more than one node is trying to access the same target device (1TB sparse file) at the same time. Has anyone set something like this up before and can give me some hints? I was looking at GFS before but it appeared to not do replication? DRBD seemed like a possibility but having more than two nodes sounded as if it might be an issue. Each server has dual quad-core Xeon processors, 64GB RAM, 8 2TB drives, and 10Gb Ethernet so I hope hardware won't be a limitation. We've constantly had trouble with every iSCSI, SAN, NAS, etc we've tried so I want to make something that is completely void of any single point of failure.
