Cardiac resynchronization therapy (CRT) uses a special type of pacemaker called a biventricular pacemaker (say "by-ven-TRICK-yuh-ler") totreat heart failure. This pacemaker sends electrical pulses to make the ventricles pump at the same time. What are the 2 types of pacemakers? Types of Pac...
sudo pcs resource create ag_cluster ocf:mssql:ag ag_name=ag1 meta failure-timeout=60s promotable notify=true 注意 當您建立資源時,Pacemaker 資源代理程式之後會定期根據可用性群組的設定,自動設定可用性群組上的 REQUIRED_SYNCHRONIZED_SECONDARIES_TO_COMMIT 值。 例如,如果可用性群組有三個同步複本,代理程...
sudo pcs resource create ag_cluster ocf:mssql:ag ag_name=ag1 meta failure-timeout=60s promotable notify=true 备注 创建资源并在之后定期更新,Pacemaker 资源代理会根据可用性组的配置自动设置可用性组上的 REQUIRED_SYNCHRONIZED_SECONDARIES_TO_COMMIT 值。 例如,如果可用性组具有三个同步副本,则代理将 REQU...

this state is used to judge whether my data is old or not. DISCONNECT Master changes other node state into DISCONNECT if Master can't detect connection of replication because of LAN failure or breakdown of Slave and so on. {state}|{sync_state} Master changes other node state into {state}...
若集群有属性start-failure-is-fatal为true(默认值),资源启动失败会导致故障计数为INFINITY, 所以资源会立马迁移 停止失败不同,若没启用STONITH,集群将无法继续 8.3 由于连接更改而移动资源 创建一个ping资源,创建为clone,一遍资源在所有节点中运行 pcs resource create ping ocf:pacemaker:ping dampen=5s multiplier=10...

If the node fails to restart it, the resource is migrated to another node. More sophosticated ways of failure management (such as trying to restart a node three times before migrating to another node) are possible using the cluster resource manager. See the Pacemaker documentation ...
