Устанавливаем ocfs apt install ocfs2-tools nano /etc/ocfs2/cluster.conf scp /etc/ocfs2/cluster.conf node2:/etc/ocfs2/ mkfs.ocfs2 -L «DrbdVol» /dev/drbd0

 99  nano /etc/default/o2cb

103  o2cb list-cluster ocfs2
104  systemctl enable o2cb ocfs2
105  systemctl start o2cb ocfs2
106  systemctl status systemctl ocfs2.service 
  107  mkdir /disk3
108  modprobe drbd

Уcтанавливаем пакеты для samba apt install samba ctdb cifs-utils

Проверяем поддержку кластера в smbd smbd -b | grep -A 1 -i cluster

node# nano /etc/ctdb/nodes 192.168.57.101 192.168.57.102

nano /etc/ctdb/public_addresses 192.168.57.200/24 eth1

Создаем папку для файла блокировок. mkdir /disk3/ctdb/

nano /etc/ctdb/ctdb.conf recovery lock=/disk3/ctdb/ctdb.lock

Внимание: Важно! писать именно recovery lock=/mnt/gluster/ctdb.lock без кавычек и прочего.

  Выключить возможность запуска smb через systemd

systemctl disable –now smb
