Upgrade Requirements for Red Hat Gluster Storage 3.1 Recommended Setup - 2nd bullet point Describe the issue: Text states: "The recommended thin pool chunk size is 256KB." But this is only recommended for the rare case that Gluster is using JBOD devices. See: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html/Administration_Guide/Brick_Configuration.html Suggestions for improvement: Remove these bullet points and keep Chapter 13.2 from the Administration guide as the one single truth.

Tested with the link provided in comment11. Thin pool perf recommendations are removed from 'recommended setup' in pre-upgrade tasks
