Hello, I try build cluster with 2 nodes + one quorum node (without pacemaker). The sequence of actions like the following:
1. setup/start corosync on TREE nodes - all right. # corosync-quorumtool -l|sed 's/\..*$//' Nodeid Votes Name 295521290 1 dev-cluster2-node2 312298506 1 dev-cluster2-node3 329075722 1 dev-cluster2-node4 2. start pacemaer on FIRST node. 3. write config with crmsh .... stonith-enabled="false" 4. .... no-quorum-policy="ignore" 5. write main config ocf:heartbeat:pgsql Like: https://github.com/t-matsuo/resource-agents/wiki/Resource-Agent-for-PostgreSQL-9.1-streaming-replication But with one VIP on master PG Resources are started on first node. 6. Next. Sync PG data with TWO node. 7. start pacemaker on TWO node. Resource started too. 8. no-quorum-policy="stop". Ok. All resources work on two nodes. See # corosync-quorumtool -l|sed 's/\..*$//' Nodeid Votes Name 295521290 1 dev-cluster2-node2 312298506 1 dev-cluster2-node3 329075722 1 dev-cluster2-node4 # corosync-quorumtool -s Version: 1.4.5 Nodes: 3 Ring ID: 12440 Quorum type: corosync_votequorum Quorate: Yes Node votes: 1 Expected votes: 3 Highest expected: 3 Total votes: 3 Quorum: 2 Flags: Quorate See crm_mon. # crm_mon -1|grep quor Current DC: dev-cluster2-node3.unix.tensor.ru - partition with quorum Now, stop pacemaker on one node. #service pacemaker stop # corosync-quorumtool -s Version: 1.4.5 Nodes: 3 Ring ID: 12440 Quorum type: corosync_votequorum Quorate: Yes Node votes: 1 Expected votes: 3 Highest expected: 3 Total votes: 3 Quorum: 2 Flags: Quorate Now, on too node stop corosync. crm_mon - says he lost a quorum, but the resources are not stopped. crm_mon -1|grep quor Current DC: dev-cluster2-node4.unix.tensor.ru - partition WITHOUT quorum But corosync says that everything is fine .... # corosync-quorumtool -l|sed 's/\..*$//' Nodeid Votes Name 295521290 1 dev-cluster2-node2 329075722 1 dev-cluster2-node4 # corosync-quorumtool -s Version: 1.4.5 Nodes: 2 Ring ID: 12440 Quorum type: corosync_votequorum Quorate: Yes Node votes: 1 Expected votes: 3 Highest expected: 3 Total votes: 2 Quorum: 2 Flags: Quorate Configs corosync: totem { version: 2 secauth: off clear_node_high_bit: yes threads: 0 interface { ringnumber: 0 bindnetaddr: 10.76.157.18 mcastaddr: 239.94.1.56 mcastport: 5405 ttl: 1 } } logging { fileline: off to_stderr: no to_logfile: yes to_syslog: no logfile: /var/log/cluster/corosync.log debug: on timestamp: on logger_subsys { subsys: AMF debug: on } } amf { mode: disabled } service { name: pacemaker ver: 1 } quorum { provider: corosync_votequorum expected_votes: 3 votes: 1 } Why this strange behavior?
