Just got myself a new dell precision 5750 with two ssd drives and have setup the two drives to be in a mirrored zpool on gentoo. However what I cant workout is how I can boot off these drives seeing as they are completely being used with zfs. And I am of the understanding that this is possible just not sure what I am doing wrong/missing.
Here is my setup;
(chroot) livecd ~ # zpool status
pool: rpool
state: ONLINE
scan: none requested
config:

mirror-0 ONLINE 0 0 0

nvme1n1 ONLINE 0 0 0
errors: No known data errors

As you can see from the output above I have a gpt disk for only /dev/nvme0n1 disk. Not too sure if this has something to do with it all.
