yes, obviously it is a good idea to check these settings, some defaults are a bit outdated for modern systems. In general there is also a "resync-after" setting where you can build a "resync chain" of resources, so that not all resources start syncing at the same time, but after each other in the defined order. Your setup looks like a Proxmox setup so you use LINSTOR, and it has a "DrbdOptions/auto-resync-after-disable" option. You might want to try if that helps and is good enough for you. disclaimer: I know it was enabled by default in a release and pulled back afterwards, but things might have improved enough, at least in such medium sized scenarios.
