Description Satoru SATOH 2016-11-11 07:28:18 UTC 
Description of problem:
Explanation of the doc [1] about # of CDSes do not look consistent.

a. 1.2.1. Installation Options: "Two or more CDS instances storage with Gluster Storage"
b. There are 3 CDSes in 'Figure 1.1. Red Hat Update Infrastructure Overview'
c. There are 3 CDSes in the instruction of Chapter 5. Shared Storage

I guess that b and c and others (3 CDSes == Gluster nodes) are correct and
a (2 CDSes) is wrong.

Version-Release number of selected component (if applicable):
RHUI 3.0.Beta 1 System Admin. Guide.

Comment 3 Radek Bíba 2016-11-11 11:57:10 UTC 
I don't think this is a bug. The diagram and the instructions work with three CDS instances, but two are technically enough. In other words, the diagram and the instructions just show examples of RHUI environments with three CDSes, which is slightly above the minimum requirements.

Also notice that the third CDS instance in the diagram is labeled "CONTENT DELIVERY SERVER N", indicating a theoretical infinite sequence of CDSes.

However, one thing should be fixed in 1.2.1. Installation Options, Option 1: Full Installation:

Two or more CDS instances storage with Gluster Storage
->
Two or more CDS instances with Gluster Storage
