I need to replace the CNI in my cluster that uses Longhorn (will potentially involve new pod IPs) - is there some common wisdom as to how best do this without explicitly scaling down all individual workloads that consume longhorn storage before doing so? I’ve done some test runs and can see Longhorn consistently being able to rebuild all its volumes before restarting workloads attached to those volumes, but I’m somewhat concerned about possible corruption

I think rebuilding replicas is an unavoidable procedure if you change the network of the cluster.
