-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Heyho guys, I'm running since years glusterfs in a small environment without big problems. Now I'm going to use glusterFS for a bigger cluster but I've some questions :) Environment: * 4 Servers * 20 x 2TB HDD, each * Raidcontroller * Raid 10 * 4x bricks => Replicated, Distributed volume * Gluster 3.4 1) I'm asking me, if I can delete the raid10 on each server and create for each HDD a separate brick. In this case have a volume 80 Bricks so 4 Server x 20 HDD's. Is there any experience about the write throughput in a production system with many of bricks like in this case? In addition i'll get double of HDD capacity. 2) I've heard a talk about glusterFS and out scaling. The main point was if more bricks are in use, the scale out process will take a long time. The problem was/is the Hash-Algo. So I'm asking me how is it if I've one very big brick (Raid10 20TB on each server) or I've much more bricks, what's faster and is there any issues? Is there any experiences ? 3) Failover of a HDD is for a raid controller with HotSpare HDD not a big deal. Glusterfs will rebuild automatically if a brick fails and there are no data present, this action will perform a lot of network traffic between the mirror bricks but it will handle it equal as the raid controller right ?
