Hi all, we have a small gluster setup currently running on two nodes, with 2x2TB disks each, serving a distributed-replica volume. We are planning to deploy this setup over more nodes, 10 to start with, possibly 20 to 50 in the future. We are already noticing a significant amount of IO operations across the two nodes when writting data to the filesystem, thus we were wondering: Will the computational overhead induce by Gluster remain more or less constant when adding more nodes, or is this overhead increasing with the number of nodes that form a volume ? I understand that under specific conditions, a client will query all nodes in order to find the actual location of a specific file: this sounds like it could become a problem if the number of nodes becomes large. Thanks for your insights, Cheers, Etienen
