Moving unassigned nvme to secondary cache pool (6.9-beta25)

[SeeGee]

I recently installed 6.9-beta25 to check out the multiple cache pool feature. I am currently using a 1tb nvme as an unassigned device for my containers and vms. It's an encrypted Btrfs partition. I bought a second (identical) drive, and would like to use them together as a raid1 cache pool. 

Can I simply create a new pool, assign both drives to the newly created pool and fire it up without having to format the original nvme again? 

 

Is it better to assign the one drive first, then add the second afterwards.? 

I understand that I will need to update the container and vm pathing of course. And I'm assuming that running a balance will probably be required.

This.

Note also that if you were already using a pool with UD you could import it directly.

@JorgeB I see your help on this thread is also relevant here. Thank you for your information. In BOTH places.
