[ClusterLabs] strange cluster state

[Václav Mach]

Hello,

I am trying to setup simple 2 node cluster. The setup is done with ansible. The whole project is available on github at https://github.com/lager1/cesnet_HA (README is written in czech, but other parts may be relevant).

The resources are:
- ping_gw
- standby_ip
- offline_file
- radiator
- racoon
- eduroam_ping
- mailto

Resource ping_gw is cloned to be run on both nodes.
All the remainning resources are added to group.



Node r2nren.et.cesnet.cz: standby
Online: [ r1nren.et.cesnet.cz ]

Full list of resources:

 Clone Set: clone_ping_gw [ping_gw]
     Started: [ r1nren.et.cesnet.cz ]
     Stopped: [ r2nren.et.cesnet.cz ]
 Resource Group: group_eduroam.cz
     standby_ip (ocf::heartbeat:IPaddr2):       Started r2nren.et.cesnet.cz
     offline_file       (systemd:offline_file): Stopped
     radiator   (systemd:radiator):     Started r1nren.et.cesnet.cz
     racoon     (systemd:racoon):       Stopped
     eduroam_ping       (systemd:eduroam_ping): Stopped
     mailto     (ocf::heartbeat:MailTo):        Started r1nren.et.cesnet.cz

How is this state even possible?




Thanks for help.

Regards,
Vaclav

The cluster consist of two servers - r1nren.et.cesnet.cz (r1, r1nren) and r2nret.et.cesnet.cz (r2, r2nren). Configuration uses group for resources to utilize created dependencies and colocation rules. When testing cluster behavior I've managed to get the cluster in an a strange state: According to the docs, the node may not run any resources when it is in standby state. Also all the resources should run on same node and all the resources should be started in the defined order. The output above does not match that. I'm not totally sure if the attached logs were created when this problem occured, but I think they should.
