Версия: pcs-0.10.2-alt1
Система: ALT Server 9.0 x86_64

Кластер из двух хостов. На обоих хостах установлены пакеты pcs pcs-pcsd и все их зависимости, добавлены записи в /etc/hosts.

Далее настраиваю по официальной документации на гитхабе:

1. # systemctl start pcsd && systemctl status pcsd

2. # passwd hacluster

3. # pcs host auth hosta hostb -u hacluster
