Cause

Birincil rol, MDM kümesinin farklı üyeleri arasında sık sık değiştirildiğinde PowerFlex ağ geçidi birincil MDM kümesine bağlanamaz. Bu durum, birden fazla MDM rolünün taşınması istendiğinde MDM'nin yeniden yapılandırılması sırasında gözlemlenmiştir.

Resolution

Bu sorunu çözmek için kullanıcının PowerFlex ağ geçidi kapsülünü yeniden başlatması gerekir.

PowerFlex ağ geçidini yeniden başlatmak için aşağıdaki komut kullanılabilir.

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