+====== PVE 內 CT 無法啟動查問題與處理紀錄 ======
+有一台 PVE Node 因為無法直接安裝 PVE 6 所以先安裝 PVE 5 在透過[[tech/pve5to6]]進行升級程序完成升級, 但這台一切都正常, 但就是無法啟動裡面的 CT , 不過由 Cluster 內其他節點正在運行中的 CT 採用 Restart Mode 遷移過來卻是可以正常啟動運作, 以下就是找尋在這樣很特別的狀況下 CT 無法啟動的原因
+  * 在這 Node 內有個 CT 編號 112 要來進行啟動
+  * 透過以下指令來啟動, 並將紀錄訊息寫到 /tmp/t.log 內 <code sh>lxc-start -n 112 --logfile /tmp/t.log</code><cli>
+root@TP-PVE-249:/var/log# lxc-start -n 112 --logfile /tmp/t.log
+lxc-start: 112: lxccontainer.c: wait_on_daemonized_start: 852 Received container state "ABORTING" instead of "RUNNING"
+lxc-start: 112: tools/lxc_start.c: main: 308 The container failed to start
+lxc-start: 112: tools/lxc_start.c: main: 311 To get more details, run the container in foreground mode
+lxc-start: 112: tools/lxc_start.c: main: 314 Additional information can be obtained by setting the --logfile and --logpriority options
+</cli><code sh>cat /tmp/t.log</code><cli>
+root@TP-PVE-249:/var/log# cat /tmp/t.log

+</cli>
+<note important>
+  * 目前還是無法找到原因, 但透過 restore 還原備份檔案後就可成功啟動
+  * 所以目前作法是這 Node 要重新啟動前必須對每個 CT 進行手動 backup, 開機後再透過 restore 還原每個 CT 的程序讓 CT 可以正常啟動
