Greetings: I am considering implementing Gluster for my storage requirements. I have a couple of questions regarding the process of adding storage to an existing cluster. Let's say that I start off quite modestly - 2 storage bricks - and after a while, I want to update this cluster to add another storage brick or two. Do I have to bring down the cluster to add a storage brick? Is it a simple matter of modifying the volfile on the individual bricks and sending a SIGHUP to each brick? Do the clients automatically recognize the added storage bricks (presuming that the storage is defined on brick and not on the client)? If I add storage to a set of bricks, do the files automatically rebalance out across all the bricks or will I have some bricks with almost no data on them while other bricks are almost filled (would the AFR translator help here)? My end goal is to essentially build a "raid-10" type array out of Gluster bricks that I can dynamically add storage to as needed. Thanks! Ron Gage
