We need to upgrade the host OS of Kubernetes nodes, upon which we deploy our fdb clusters. The OS upgrade will reboot the underlying node and restart fdb pods. This causes rebalance on fdb pods. This could make the OS upgrade on many nodes time consuming, and we are also afraid possible issues caused by rebalance.
We are thinking to shutdown fdb clusters first (at least for non-production fdb clusters), do the host OS upgrade, then bring up the cluster. This can avoid rebalance.
But we have never shutdown a fdb cluster, and I don’t find the shutdown cmd for fdb.
Is there a way to shutdown a fdb cluster, and bring it up later?
