Autofs works with sshfs. I use it for mounting anything over a network. It automounts on demand and disconnects a mount after a period of inactivity.

I use porkbun and ddclient (https://ddclient.net/). Not sure if that helps you or not but there it is

(I am OP had to create a new account because apparently my other instance is de federated from lemmy.ml)

Why are you using ZFS on a single drive?

TL;DR: life happens.

It’s a small homelab. I had grand plans to add another one for a mirror. Had a baby, didn’t get to it. etc etc.

Do you actually have enough memory to handle ZFS?

This host has 32GB.

Is the memory ECC?

No, it is not ECC

Is the disk connected to a RAID controller?

No
