Good morning,
I am building a block LVM KVM cluster with 4 machines, but i am having a
strange problem which keeps me busy for days now, i am using a standard
Centos 7 server as frontend and Centos 7 nodes with opennebula and
opennebula-server installed.
software installed
opennebula-ruby-4.8.0-1.x86_64
opennebula-common-4.8.0-1.x86_64
opennebula-sunstone-4.8.0-1.x86_64
opennebula-4.8.0-1.x86_64
opennebula-server-4.8.0-1.x86_64
I also installed pcs-0.9.115-32.el7_0.1.x86_64 to use clvmd en dlm locks
on the opennebula nodes and frontend.
Now the problem i am facing i have installed pcsd (ruby) and opennebula
(ruby) on the same machine, when i install rack and sinatra via gems as
ordered by the install in the documentation the psc daemon binds only to
the localhost interface. If i uninstall sinatra and rack then the psc
daemon listens as ordered via the config file on all interfaces but
opennebula won't start!
After installing sinatra via gems their are 2 versions of sinatra on the
system
/usr/lib/pcsd/vendor/bundle/ruby/gems/sinatra-1.4.4/lib/sinatra
/usr/local/share/gems/gems/sinatra-1.4.5/lib/sinatra
So i assume something is "overruling" BindAddress directive in the
config of pscd on centos 7 when i install the software needed to run
opennebula. I have tried setting the BindAddress directive in ssl.rb to
*, nil and :: but nothing fixes the problem also my knowledge of ruby is
to low to investigate further.
see below howto reproduce this problem
[root@cloudmanager rack-1.6.0]# !lsof
lsof -i | grep ruby
ruby 1368 root 9u IPv6 1474379 0t0 TCP
localhost:efi-mg (LISTEN)
ruby 1368 root 10u IPv4 1474380 0t0 TCP
localhost:efi-mg (LISTEN)
ruby 13803 oneadmin 10u IPv4 913310 0t0 TCP *:9869 (LISTEN)
[root@cloudmanager rack-1.6.0]# gem uninstall sinatra rack
Successfully uninstalled sinatra-1.4.5
Successfully uninstalled rack-1.6.0
[root@cloudmanager rack-1.6.0]# systemctl restart pcsd.service
[root@cloudmanager rack-1.6.0]# !lsof
lsof -i | grep ruby

ruby 13803 oneadmin 10u IPv4 913310 0t0 TCP *:9869 (LISTEN)
[root@cloudmanager tmp]# gem install sinatra
Successfully installed rack-1.6.0
Successfully installed sinatra-1.4.5
[root@cloudmanager tmp]# systemctl restart pcsd.service
[root@cloudmanager tmp]# !lsof
lsof -i | grep ruby
ruby 4551 root 9u IPv6 1740682 0t0 TCP
localhost:efi-mg (LISTEN)
ruby 4551 root 10u IPv4 1740683 0t0 TCP
localhost:efi-mg (LISTEN)
ruby 13803 oneadmin 10u IPv4 913310 0t0 TCP *:9869 (LISTEN)
Any tips how i can solve this problem?
Regards
Constan
