Hi Everyone,
Our company have 15-nodes asynchronous cluster without actually
configured FENCING/STONITH (as I think) features.
The DC node log getting tons of messages like in subject:
pengine: warning: handle_startup_fencing: Blind faith: not fencing
unseen nodes
the message repeated 15 times before next 15 messages:
pengine: info: determine_online_status: Node Node1 is online
...
pengine: info: determine_online_status: Node Node15 is online
The issue looks like similar to:
http://oss.clusterlabs.org/pipermail/pacemaker/2014-June/021995.html
but with own features.
Our variables:
Oracle Linux Server release 6.8
Pacemaker 1.1.14-8.el6
Corosync Cluster Engine, version '1.4.7'
CMAN 3.0.12.1
Cluster Properties:
cluster-infrastructure: cman
cluster-recheck-interval: 1
dc-version: 1.1.14-8.el6-70404b0

last-lrm-refresh: 1481444797
maintenance-mode: false
no-quorum-policy: ignore
startup-fencing: false

Example of /etc/cluster/cluster.conf:
<cluster config_version="96" name="cluster">

<clusternodes>
<clusternode name="Node1" nodeid="1">
<fence>
<method name="pcmk-redirect">
<device name="pcmk" port="Node1"/>
</method>
</fence>
<altname name="Node1.name"/>
</clusternode>
<...>
<clusternode name="Node2" nodeid="15">
<fence>
<method name="pcmk-redirect">
<device name="pcmk" port="Node2"/>
</method>
