# 移除叢集

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
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://kawsing.gitbook.io/opensystem/andoid-shou-ji/pomoxve/fu-lu/untitled-6.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
