我已经使用 pcs (corosync/pacemaker/pcsd) 配置了一个两节点物理服务器集群 (HP ProLiant DL560 Gen8)。我还使用 fence_ilo4 在它们上配置了围栏。
如果一个节点出现故障（在 DOWN 下，我的意思是断电），就会发生奇怪的事情，第二个节点也会死掉。Fencing 会杀死自己，导致两台服务器都离线。
我该如何纠正这种行为？
我尝试的是在下面的部分中添加“ wait_for_all: 0”和“ ” 。但它仍然会杀死它。expected_votes: 1/etc/corosync/corosync.confquorum
在某些时候，要在其中一台服务器上执行一些维护，并且必须将其关闭。如果发生这种情况，我不希望其他节点停机。
这是一些输出
