将 PVE 版本从 6.x 升级到 7
PVE 集群从 6.x 升级到 7 的过程,以及一些问题。
升级过程:
首先推荐看官方文档:
https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0
先升级到 6.4
apt update
apt dist-upgrade升级到 7.0
升级前的检查
运行 pve6to7,检查是否有错误。先解决掉所有错误,然后继续。有一些警告是没关系的,可以忽略。
替换源版本
sed -i ‘s/buster/updates/bullseye-security/g;s/buster/bullseye/g’ /etc/apt/sources.list
echo “deb https://enterprise.proxmox.com/debian/pve bullseye pve-enterprise” > /etc/apt/sources.list.d/pve-enterprise.list
sed -i -e ‘s/buster/bullseye/g’ /etc/apt/sources.list.d/pve-install-repo.list
如何安装了 ceph(ceph only)
echo “deb http://download.proxmox.com/debian/ceph-octopus bullseye main” > /etc/apt/sources.list.d/ceph.list
注意1:查看 /etc/apt/sources.list.d 确认所有的源都更新到了 bullseye,有一些自己添加的源需要手动更新下。
注意2:如果提示缺少/etc/apt/sources.list.d/pve-install-repo.list 就新建一个,文件内容如下:
1
deb http://download.proxmox.wiki/debian/pve bullseye pve-no-subscription
安装
如果中途遇到问题,可以参考其他问题
apt update
apt dist-upgrade
等待下载&安装,时间会比较久。
下载完成后,有如下提示:

Configuration file ‘/etc/issue’
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer’s version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** issue (Y/I/N/O/D/Z) [default=N] ?
我在第一个节点选择了 D,为了了解更多安装过程的信息。后续的其他节点安装就选 Y 了。
Restart services during package upgrades without asking?
第一个节点选了 NO,第二次直接 YES
What do you want to do about modified configuration file sshd_config?
选择:install the package maintainer’s version
Processing triggers for initramfs-tools (0.140) …

Running hook script ‘zz-proxmox-boot’..
Re-executing ‘/etc/kernel/postinst.d/zz-proxmox-boot’ in new private mount namespace..
No /etc/kernel/proxmox-boot-uuids found, skipping ESP sync.
至此已安装完成。这个信息可以忽略。
输入 pveversion
查看版本号。
1 | pve-manager/7.1-10/6ddebafe (running kernel: 5.4.73-1-pve) |
安装完成后
apt update
apt dist-upgrade
可能会遇到下面的问题,可以忽略,或者重启下。

E: Some index files failed to download. They have been ignored, or old ones used instead.
忽略即可,重启后消失。
之前的一个在 A节点 无法管理 B 节点磁盘的bug 也随着这次升级解决了。
在安装时可能遇到的其他问题:
提示删除 ‘proxmox-ve’
Upgrade wants to remove package ‘proxmox-ve’
首先检查是否使用了镜像,如果使用了镜像,要先将镜像恢复到 官方源。
debian官方源:deb.debian.org
如果没有使用镜像,则可能是因为 linux-image-amd64 引起的冲突。直接删除这个包:
apt remove linux-image-amd64
升级后可能遇到的问题:
LXC 容器中的 docker 不能使用
因为 cgroup 的版本发生变化,docker 在 20.10.7 之后的版本才能使用 cgroup v2,升级docker 到最新版即可。
另外一种办法设置 systemd.unified_cgroup_hierarchy=0
