Hi Michael!
Following is the same scenario (same config) again, this time with ping
scores:
1. Corosync on both servers restarted:
============
Last updated: Wed Feb 9 09:05:59 2011
Stack: openais
Current DC: server1 - partition with quorum
Version: 1.0.9-74392a28b7f31d7ddc86689598bd23114f58978b
2 Nodes configured, 2 expected votes
2 Resources configured.
============
Online: [ server1 server2 ]
failover-ip (ocf::heartbeat:IPaddr): Started server1
Clone Set: clonePing
Started: [ server2 server1 ]
Migration summary:
* Node server1:
* Node server2:
Why there is no summery at all?
2. # crm node standby server2
(only server1 is pinging)
Node server2: standby
Online: [ server1 ]
failover-ip (ocf::heartbeat:IPaddr): Started server1
Clone Set: clonePing
Started: [ server1 ]
Stopped: [ pingtest:0 ]
Migration summary:
* Node server1: pingd=10
* Node server2: pingd=0
I think this looks fine.
3. # crm node online server2
(both servers are pinging again)
Online: [ server1 server2 ]
failover-ip (ocf::heartbeat:IPaddr): Started server1
Clone Set: clonePing
Started: [ server2 server1 ]
Migration summary:
* Node server1: pingd=10
* Node server2: pingd=0
Why is pingd=0 for server2? I would expect it to be 10 too.
4. # crm node standby server2
(only server1 is pinging)
Node server2: standby
Online: [ server1 ]
failover-ip (ocf::heartbeat:IPaddr): Started server1
Clone Set: clonePing
Started: [ server1 ]
Stopped: [ pingtest:0 ]
Migration summary:
* Node server1: pingd=10
* Node server2: pingd=0
5. server1 pings will be blocked in the firewall, after 10 seconds:
Node server2: standby
Online: [ server1 ]
failover-ip (ocf::heartbeat:IPaddr): Started server1
Clone Set: clonePing
Started: [ server1 ]
Stopped: [ pingtest:0 ]
Migration summary:
* Node server1: pingd=0
* Node server2: pingd=0
Seems correct, as server1's pings are blocked and server2 is in standby
mode.
6. # crm node online server2
(both servers are pinging again, server1's pings are still blocked)
Online: [ server1 server2 ]
failover-ip (ocf::heartbeat:IPaddr): Started server1
Clone Set: clonePing
Started: [ server2 server1 ]
Migration summary:
* Node server1: pingd=0
* Node server2: pingd=0
Here, it should switch to server2. And why is server2's pingd=0 instead
of 10?
7. # crm node standby server1
(only server2 is pinging)
Node server1: standby
Online: [ server2 ]
failover-ip (ocf::heartbeat:IPaddr): Started server2
Clone Set: clonePing
Started: [ server2 ]
Stopped: [ pingtest:1 ]
Migration summary:
* Node server1: pingd=0
* Node server2: pingd=0
Even if server1 is in standby, the pingd value of server2 is 0 instead
of 10.
What am I doing wrong?
Thanks
Klaus
