Running umbrelOS 1.2.2+ in ZFS mirror?

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).

Thank you for the your answer.

What do you think of setting up a ZFS mirror in Proxmox and running umbrelOS on it as a VM? That could be a solution, couldn’t it?

Or my motherboard also provides me an option to set up a RAID 1 configuration. Not sure if umbrelOS could be installed in that way.

This is the best way to run Umbrel IMO.

Perfect. Thank you for your advice.

I think I will run Proxmox on a small SATA SSD and create a ZFS mirror for 2x 2TB NVMe SSDs for umbrelOS.
