ZFS Pool disappeared after power flickered

[Ankelbiter12]

Hey Guys, 

    I work a lot so I only have a couple random hours each day to work on this but I've barely any idea where to start. The power flickered in my room where my little server is running and restarting it doesn't help. My network folders aren't there on other computers, so I started with seeing if ZFS is working properly on the Ubuntu Server, it says no pools available, zfs list shows lo datasets avaailable. It's a pretty basic setup where I've got 3 hard drives plugged in as network storage, using a samba share, I'm just not sure where to start. I did also run df, which showed the drives as:

Which I believe reassures me that my stuff isn't gone, just hidden in limbo.

Maybe you can just import the pool again and it only got unmounted for some reason? 

In freenas it's pretty easy to import, I don't know for Ubuntu Server.

When I first made the server, I had an issue where the pool would unmount, and I would type something like “zfs import zpool”. That’s not working unfortunately this time around which makes me think it’s a way worse problem

I figured it out, I must have been using the wrong command or syntax, I just needed to run "sudo zpool import new-pool", I think I also couldn't remember what I called it, I'd consider renaming it to the name of the network, but it seems I'd need to export, then import, and I feel like that could be problematic and nnot worth it since I already have other things pointing to new-pool and they might get confused and I'd need to update the systems to tell them what to point to instead.
