cluster not ready - no quorum?\
造成 Cluster 錯誤的原因中，最常見的就是節點之間網路的斷線， Cluster 中節點數量低於 2 時， Cluster 就會被鎖住，會陷入「no quorum」的狀態。這是因為 Proxmox VE Cluster 預設期待 Cluster 中必須要有 2 個節點(Node)以上，可是因為網路斷線的緣故，才會出現「Quorum: 2 Activity blocked」這個狀態。

```
暫時把 Cluster 的期待數量從 2 降低為 1
# pvecm expected 1

重新啟動 Proxmox VE Cluster
# service pve-cluster restart

```

移除master node

```
systemctl stop pve-cluster
systemctl stop corosync

pmxcfs -l

rm /etc/pve/corosync.conf
rm /etc/corosync/*
rm -rf /var/lib/pve-cluster/*

killall pmxcfs
systemctl start pve-cluster
```
