CentOS 7 Pacemake/Corosync

Post #1 of 3 (3384 views)

Hi,

I'm trying to build a Pacemaker/Corosync Cluster on CentOS7. The default
Corosync configuration with one ring is working but then I only have 1
ring and no encryption.

RING ID 1
id = 10.10.10.1
status = ring 1 active with no faults

I've tried to activate the following configuration but it doesn't work.

[root@linsrv006 corosync]# cat /etc/corosync/corosync.conf
totem {
version: 2
secauth: on
threads: 0
rrp_mode: active
interface {
ringnumber: 0
bindnetaddr: 192.168.0.0
mcastaddr: 226.94.42.7
mcastport: 5411
}
interface {
ringnumber: 1
bindnetaddr: 10.10.10.0
mcastaddr: 226.94.42.11
mcastport: 5419
}
token: 10000
token_retransmits_before_loss_const: 40
rrp_problem_count_timeout: 20000
nodeid: 3
}
quorum {
provider: corosync_votequorum
expected_votes: 3
}

logging {
to_syslog: yes
}

The problem is also than, that pcs status is showing 3 nodes.

[root@linsrv006 corosync]# pcs status
Cluster name:

Please support me to fix my Corosync issue.

Many thanks & regards - Willi

Hi,

I can't offer a solution, but I remember having run into similar issues
when the output of hostname showed the FQDN.

Maybe that helps you narrow down the problem.

Best regards

Hi Lukas,

thanks for the feedback. I''ve changed my configuration to use hostnames
without FQDN but the Cluster name: is still not showed. I'll wait for
CentOS-7.1, maybe the latest Pacemaker package will fix this issue.

Best regards,
Willi
