Hi, we have a system consisting of 4 nodes, each running CentOS-5.5 and raid10 on ext4, and using gluster 3.2.6. Now we want to expand this system with a 5:th node, and my plan was to use the same setup (5.5, raid10, ext4, 3.2.6). However, due to hardware issues I can't install CentOS-5.5 on the new machine, and I'm wondering of my options here. Should I: 1. Go for the lowest version of CentOS the new hardware can take, and hope this isn't affected by the ext4-issue. or 2. Should I opt for newer OS, like CentOS-6.3, and use xfs on the new machine? That is, would it be an issue to have bricks using different underlying file systems? In both these cases I intend to use 3.2.6. Regards, /jon
