PVE 6 升級到 7 紀錄
實際採用 PEV 6 與 PVE 7 兩組 Cluster 並存的模式移轉運行, 處理紀錄請參考 安裝 PVE 7 與移轉 PVE 6 VM/CT 執行紀錄
- 升級 cgroup-v2 需要讓 CT 內的 OS 升級至版本 Exp. CentOS 7 → CentOS 8
- 因環境有大量 CT 使用 CentOS 7, 考慮升級過程還能讓服務持續運作, 決定採用 PEV 6 與 PVE 7 兩組 Cluster 並存的模式移轉運行
依照官方的 wiki 說明升級程序, 似乎不太困難, 因此將實際的升級程序操作紀錄在底下
升級程序
預先準備
- 將現在 PVE 6 所有主機都先生級到最新版本 Exp. 6.4-13 (有更新到 linux-kernel 需要重開機)
- 有同時安裝 PBS(Proxmox Backup Server)需要先將 PBS 升級到 2.x 參考 [draft]PBS 1 升級到 2 紀錄
- 確定可以穩定存取每一台的參數檔儲存區 (萬一有異常可以直接進去手動修改)
- 確定目前的 Cluster 是健康穩定狀態
- 驗證與測試所有 VM 與 CT 的備份都是正確 (萬一出現災難還有降災還原的機會)
- 確定是正確升級存儲庫的配置
- 根目錄至少要有 4GB 的磁碟空間
執行升級
- 所有主機都執行升級檢測工具
pve6to7 --full
如果有使用 CT 裡面是 CentOS7/Ubuntu16 .. 會出現這個警告
WARN: Found at least one CT (103) which does not support running in a unified cgroup v2 layout. Either upgrade the Container distro or set systemd.unified_cgroup_hierarchy=0 in the Proxmox VE hosts' kernel cmdline! Skipping further CT compat checks.
- 將所有 VM/CT 移到其他主機
- 避免升級 PVE 7 後會更變 Bridge 的 MAC , 所以可以選擇以下其中一個方式處理:
- 安裝 ifupdown2
apt install ifupdown2 -y ifreload -a
- 在 /etc/network/interfaces 內針對 vmbr0 … 進行指定現有的 MAC , Exp.
: auto vmbr0 iface vmbr0 inet static address 192.168.X.Y/24 hwaddress aa:bb:cc:12:34 # ... remaining options
- 更新 apt repo 設定
apt update apt dist-upgrade sed -i 's/buster\/updates/bullseye-security/g;s/buster/bullseye/g' /etc/apt/sources.list
- 進行 Debian Bullseye 與 PVE 7 更新
apt update apt dist-upgrade
