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:


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'
