Description Chris Blum 2016-11-01 09:40:04 UTC
Document URL: 
https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html/Installation_Guide/sect-In-Service_Software_Upgrade_from_Red_Hat_Storage_2.1_to_Red_Hat_Storage_3.0.html#sect-Pre-upgrade_Tasks

Section Number and Name: 
9.2.1.1. 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.

I feel the same way.

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

Moving to CLOSED CURRENTRELEASE since RHGS 3.2 GA was yesterday. All documentation is available from https://access.redhat.com/documentation/en/red-hat-gluster-storage/.
