Делал по этому мануалу https://pve.proxmox.com/wiki/DRBD9
При добавлении нод получал такой выхлоп:
root@node01:~# drbdmanage add-node -q node02 10.0.1.2
WARNING:root:Could not read configuration file '/etc/drbdmanaged.cfg'
Operation completed successfully
Operation completed successfully
Executing join command using ssh.
IMPORTANT: The output you see comes from node02
IMPORTANT: Your input is executed on node02
WARNING:root:Could not read configuration file '/etc/drbdmanaged.cfg'
Error: Operation not allowed on satellite node
Всего 3 ноды
Кстати что означет ключ "-q"?
В итоге получаю вот что:
root@node01:~# drbdmanage list-nodes
WARNING:root:Could not read configuration file '/etc/drbdmanaged.cfg'
