Yes. It is not well-tested yet, but that is the intention behind it. The details are a bit more complex (e.g., the controller can select the network interface that it uses for communication with the satellite, and that can be a different one than those used for connecting DRBD resources, etc...). I have used this command in the past to change resource configurations from Ethernet to Infiniband, from IPv4 to IPv6, etc., so that's all supposed to work. > Will the above command also update drbd resource configuration files > to the new ip addresses *without* the need to re-create them ?
