RHEL 6.6 - pcsd GUI availability

Latest response

Hi,

I have just installed RHEL 6.6 (Red Hat Enterprise Linux Server release 6.6) and installed the pacemaker package in order to use the HA solution:

# rpm -q pcs
pcs-0.9.123-9.el6.x86_64

# rpm -q ruby
ruby-1.8.7.374-2.el6.x86_64

# pcs cluster status
Cluster Status:
 Last updated: Thu Jan 14 18:47:52 2016
 Last change: Thu Jan 14 16:28:07 2016
 Stack: cman
 Current DC: eastapp1 - partition with quorum
 Version: 1.1.11-97629de
 2 Nodes configured
 3 Resources configured

PCSD Status:
  eastapp1: Online
  eastapp2: Online

===

I want to use the pcsd GUI.. I read online that the RHEL 6.6 supports it but, when I was trying to access it I was getting the PCSD DISABLED message on the browser...

So I went to the pcsd.rb file and found out that there was a isrehl6 tag there that pointed to the disabled_gui to true. That was weird since the GUI suppose to work with RHEL6.6

What I did was to set it to false:

configure do
  ISRHEL6 = is_rhel6
  DISABLE_GUI = <false>

And it worked... I was able to log in the GUI using the hacluster user... but when I try to add an existing cluster I get this on the pcsd.log
