退出集群

systemctl stop pve-cluster.service
systemctl stop corosync.service
pmxcfs  -l
rm /etc/pve/corosync.conf
rm -rf /etc/corosync/*
killall pmxcfs
systemctl start pve-cluster.service
cd /etc/pve/nodes
rm -rf node_name

安装，这里不详述

换源并更新

当然还有debian的源

deb http://mirrors.aliyun.com/debian bullseye main contrib

deb http://mirrors.aliyun.com/debian bullseye-updates main contrib

# security updates
deb http://mirrors.aliyun.com/debian-security bullseye-security main contrib

设置gvt-g

这里新版本的pve可以更改/etc/kernel/cmdline

intel_iommu=on i915.enable_gvt=1

然后

proxmox-boot-tool refresh

加入集群

恢复zfs存储池

zpool import -f xxx

编辑zfs内存限制

/etc/modprobe.d/zfs.conf

options zfs zfs_arc_max=5368709120
