Настроить время 

Установка DRBD
apt install drbd-utils
 nano /etc/drbd.d/r0.res
scp /etc/drbd.d/r0.res node2:/etc/drbd.d/
drbdadm create-md r0
ssh node2 drbdadm create-md r0
 service drbd start
drbdadm -- --overwrite-data-of-peer primary r0

   80  watch cat /proc/drbd
   81  drbdadm sh-resources
   82  drbdadm cstate r0
   83  drbdadm dstate r0
   84  drbdadm role r0
   85  drbdadm role r0
   86  drbdadm dstate r0

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
  100  scp /etc/default/o2cb node2:/etc/default/
    101  o2cb register-cluster ocfs2
  102  o2cb list-clusters
  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
  109  cat /proc/drbd
  115  systemctl enable drbd o2cb ocfs2
  o2cb list-clusters
  133  o2cb list-cluster ocfs2
  134  systemctl status  o2cb ocfs2



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.

node#
for i in 00.ctdb 10.interface 50.samba; do ctdb event script enable legacy $i; done

node#
ctdb event script list legacy

  91.lvs
* 95.database

for i in 00.ctdb 10.interface 50.samba; do ctdb event script enable legacy $i; done

    запустить ctdb

systemctl enable --now ctdb


Настройка samba

    Выключить возможность запуска smb через systemd

systemctl disable --now smb
