Symptoms

PowerFlex Manager 4.x :  嘗試使用 cmo.maintenance.mode=true 標記節點會傳回錯誤:「cmo.maintenance.mode」已經有值 (false),而 --overwrite 為 false
delladmin@mvm03:~> kubectl label node mvm01 cmo.maintenance.mode=true
error: 'cmo.maintenance.mode' already has a value (false), and --overwrite is false

delladmin@mvm03:~> sudo su -
mvm03:~ # kubectl label node mvm01 cmo.maintenance.mode=true
error: 'cmo.maintenance.mode' already has a value (false), and --overwrite is false

Cause

先前的韌體更新已將 cmo.maintenance.mode 設定為 false 升級後,而非移除節點上的標籤。嘗試標記節點以使其再次進入維護模式時,預計不會設定 cmo.maintenance.mode=false。

Resolution

執行以下命令以取消設定標籤:-
kubectl label node <nodename> cmo.maintenance.mode-

Example:-
mvm03:~ # kubectl label node mvm01 cmo.maintenance.mode-
node/mvm01 unlabeled

現在您可以繼續執行以下命令,以 cmo.maintenance.mode=true label 標記節點
