Hi Martin.
for how long you turned off the other node? I suspect that you need to configure time-outs to the cluster. Additional cluster parameters can be found here.

Hi Martin.
if you could provide us your config like, put the output of the command below.
pcs configure show
or
crm configure show
maybe we could get a better idea of your setup.

I'm sorry. My systems are fully updated CentOS 6.5. I'm using only standard centos repositories.

Hi,
For a testing purposes I'm trying to create two node HA environment
for
running some service (openvpn and haproxy). I installed two CentOS
6.4
KVM guests.
Iirc CentOS 6.5 came with several updates to cluster related packages
so
you may want to investigate and update to 6.5.
Regards, Patrick
Hy Martin, I've not looked carefully at what your problem is and don't know how skilled in HA you are but I heartily suggest you - if you haven't done before - to read/study Digimer's tutorial https://alteeve.ca/w/AN!Cluster_Tutorial_2
I think it's unbeatable!

Thanks for your interest and for your help. Here is the output from command (pcs config show)
[root@lb1 ~]# pcs config show Cluster Name: LB.STK Corosync Nodes:

When I start cluster after reboot of both nodes, everythings looks fine. But when shoot command "pcs resource delete OPENVPN" from node lb1 in the log starts to popup these lines: Jan 15 13:56:37 corosync [TOTEM ] Retransmit List: 202 Jan 15 13:57:08 corosync [TOTEM ] Retransmit List: 202 203 Jan 15 13:57:38 corosync [TOTEM ] Retransmit List: 202 203 204 Jan 15 13:58:08 corosync [TOTEM ] Retransmit List: 202 203 204 206 Jan 15 13:58:38 corosync [TOTEM ] Retransmit List: 202 203 204 206 208 Jan 15 13:59:08 corosync [TOTEM ] Retransmit List: 202 203 204 206 208 209
I also noticed, that these retransmit entries starts to appear even after some time (7 minutes) from fresh cluster start without doing any change or manipulation with cluster.
Thanks
