本文使用的corosync的版本如下：corosync-3.1.5-2.el8.x86_64
操作系统版本：Red Hat Enterprise Linux release 8.1 (Ootpa)
对于pacemaker高可用集群中,corosync是非常重要的，服务的启动：systemctl restart corosync.service
其默认配置文件位于 /etc/corosync/corosync.conf
这里我们可以看到，默认情况下，其日志相关的配置段如下：
logging {
to_logfile: yes
logfile: /var/log/cluster/corosync.log
to_syslog: yes
timestamp: on
}
因此可以看到日志会存储到2个地方，除了定义的logfile之外，也会写入到syslog，也即 /var/log/messages
两种日志的内容都会是一样的，只是格式略有小小差异、如下：
# corosync.log Feb 11 11:04:16 [2483] QQ-5201351 corosync info [KNET ] link: host: 2 link: 0 is down Feb 11 11:04:16 [2483] QQ-5201351 corosync info [KNET ] host: host: 2 (passive) best link: 0 (pri: 1) Feb 11 11:04:16 [2483] QQ-5201351 corosync warning [KNET ] host: host: 2 has no active links Feb 11 11:04:17 [2483] QQ-5201351 corosync notice [TOTEM ] Token has not been received in 2250 ms Feb 11 11:04:18 [2483] QQ-5201351 corosync notice [TOTEM ] A processor failed, forming new configuration: token timed out (3000ms), waiting 3600ms for consensus.

而对于 /var/log/messages 也会写入一份
# messages Feb 11 11:04:16 QQ-5201351 corosync[2483]: [KNET ] link: host: 2 link: 0 is down Feb 11 11:04:16 QQ-5201351 corosync[2483]: [KNET ] host: host: 2 (passive) best link: 0 (pri: 1) Feb 11 11:04:16 QQ-5201351 corosync[2483]: [KNET ] host: host: 2 has no active links Feb 11 11:04:17 QQ-5201351 corosync[2483]: [TOTEM ] Token has not been received in 2250 ms Feb 11 11:04:18 QQ-5201351 corosync[2483]: [TOTEM ] A processor failed, forming new configuration: token timed out (3000ms), waiting 3600ms for consensus.

主要是因为 to_syslog: yes 这一个配置的影响，如果不想corosync的日志写入到 /var/log/messages ，将其修改成no就可以了
注：直接删除这行配置，也会写入，因为不写默认就是yes，关于/etc/corosync/corosync.conf配置文件，注释可以使用#号
还有需要注意的修改配置文件后，还需要执行如下几条命令，让配置同步其他节点、和立即生效
pcs cluster sync pcs cluster reload corosync corosync-cmapctl
说明：最后一条只是查询当前内存中corosync的配置
