I’m considering upgrading the hardware configuration of my Lightning Node running on umbrelOS. I was wondering if it would be worth ensuring against SSD failure by operating the entire system in ZFS mirror mode. Do you think this is a good idea? Why or why not? If so, what would be the best way to implement it?
Yes ZFS is generally a great idea for ensuring against data failure when running a node. This used to be possible by setting up ZFS during Ubuntu setup, and then installing Umbrel over the top. Unfortunately, since Umbrel changed the way the OS is installed this is no longer possible and you’d have to look into self-rolled options (Check into Minibolt https://minibolt.minibolt.info/ for example).
