Cause

当主角色在 MDM 群集的不同成员之间频繁切换时，PowerFlex 网关无法连接到主 MDM 群集。在 MDM 重新配置期间，当请求移动多个 MDM 角色时，会观察到这种情况。

Resolution

要解决此问题，用户必须重新启动 PowerFlex Gateway pod

。以下命令可用于重新启动 PowerFlex 网关。

kubectl delete pod -n powerflex $(kubectl get pods -A | grep block-legacy-gateway | grep -v mds | grep -i running | awk ' {print $2}')
