Cannot `zpool import <NameOfArray>` for a USB connected ZFS disk.

Thanks for the feedback

Aw nuts, apparently I only sometimes need to run `zpool import` (no arguments) first.

Rebooting the 12.0 NAS to check again. Okay, strange, this time I also did not need to run `zpool import` (no arguments) first. 

Okay, sorry I didn't even get to contribute any interesting data. Ticket can be closed. 

Edit: Maybe it was just a PEBKAC / ID-ten-T / "Bless his soul" error:

```

{{root@MiniNAS[~]# zpool import OfflineA5}}

cannot import 'OfflineA5': no such pool available

```

Pool is actually named OfflineA4. I also have another OfflineB5. Looks like I need a labeller, or my memory engrams need to be stored on a file system that resists bit rot. 

For comparison, I don't need to first run `zpool import` on 11.3.

I guess I was spoiled!

Thanks guys, sorry for the question, but now I learned. Ticket can be closed. 

Sorry, it was my error. I did not run `zpool import` (no arguments) first. 

Now that I have done as suggested (`zpool import` then `zpool import <VolumeName>`), the zpool does import as expected (transcript:

). 

@Colin Ng Can you run zpool import command by itself with disk connected and share the output?
