Thanks for your response. My actual need here is to familiarize myself with Gluster...
This is really a lab project for me to try and get as much experience with GlusterFS as I can to see what use it might be. I've done some thinking and I am going to use the two hosts with 146GB disks in for my oVirt cluster now. So I am using the 2 x Dell 2950s with 6 x 300GB disks in each for my Gluster. So my needs now would be that I want as much storage - but able to lose a disk and not lose data, so not RAID 0. So could you tell me if there are advantages or disadvantages to creating a RAID5 out of the 6 x 300 GB disks on each 2950 server and then allocate whatever is left after loading the operating system and Gluster as a brick? Or not create RAID and use each disk as brick. I expect creating the RAID as the Dell Perc controller is pretty efficient would be better than software defined RAID - for performance anyway? Thanks again, I really appreciate the advice.

The only goal set out below is that you, "want to get as much storage out of these as possible." This would mean raid0 or 1 brick per disk with a distribute array (no replication). Identically sized bricks are best. Often if the disk sizes are mixed, raid or partitioning are used to create bricks of the same size.

I have two dell 2950s fully populated with 5 x 300GB 10K disks. I want to get as much storage out of these as possible. I have two more dell 2950s each with 4 x 146GB 10K disks. Should I build one RAID 5 container on the first two servers, load up CentOS7 and then Gluster on that? using the unused partition of what is left after loading CentOS? Or should I be looking at moving physical disks around and putting the smaller 146 GB disks as RAID 1 in each of the 4 servers for OS and distributing the 300GB disks amoung all the servers and maybe pick some more up on Ebay to get all 4 servers identical? Would appreciate any advice on short notice as I have nothing else to do today for once and would just as soon at least start off on the right foot!
