You can also have a look at this one:

As stated, it's not supported and you're on your own for:
- Disk replacements
- The actual setup
- Not nuking the other pool on the same disk with the TrueNAS installer or something like that
Possible, yes, but it's of limited usefulness. I can imagine it making the setup process a bit easier (just mirror the existing install to the prepared partition on the new disk), but it would be basically pointless in production after that. Of course, since it's a mirror, you can easily remove the USB drive once the process is complete.
Hi
@Ericloewe
I guess the fact that I am on my own when it comes to my setup basically applies for my entire setup. haha
Seriously, I understand the risks involved but actually running it from the SSD gives me more confidence instead of running it from the USB stick - in terms of reliability.
In preparation I already deleted the pool that was on the SSD. So I am basically looking at an empty SSD now.
I found the thread you have mentioned as well. But reading through the command lines I find the one I have linked very understandable.
There is just one question I have regarding the thread I have linked when it comes to mirroring. It says:
#setup boot as mirror from our usb drive (usb drive B is da0, da0p2 is the freenas-boot pool)
zpool attach freenas-boot /dev/da0p2 /dev/ada0p3
#wait for resilver! run 'zpool status' to check status
zpool offline freenas-boot /dev/da0p2
zpool detach freenas-boot /dev/da0p2
Here - from what I understand - you are actually taking the exact same partition from the USB stick and mirror it to the newly created partition on the SSD, correct? This would mean I 'copy' all of the files and configurations from the USB stick as well.
I will back up in any case and don't have a problem with a fresh install. Hmm
I guess one thing to consider are the partition sizes I am creating on the SSD. Because if they are not identical as the ones on the USB stick, I will waste space if I just blindly mirror from USB-->SSD. Hmm
